Learn The Basics of Boundary Surveying Macon

Posted on August 17, 2013 by MaconSurveyor

Investing in land or real property may be the most expensive investment you’ll make in your lifetime. Thus, it is wise to learn a little more about real estate and be aware of the significance of boundary surveying before making such investments.

Boundary Survey Defined

Let’s first define boundary surveying. Boundary surveying is the verification of property lines of a parcel of land as detailed in the description in the deed. It may also show all the structures found on the property including any easements and encroachments, and also the restrictions imposed by local governing authorities.

To avoid unnecessary expenses and free you from frustrations brought by unexpected lawsuits, it is vital to conduct a boundary survey in the Macon area before purchasing or selling a parcel of land. A survey is also required before subdividing a lot, building structures or improving the property to make sure that you don’t end up having to move a building or resolve a boundary dispute with your neighbors.

Other Uses of a Boundary Survey

A boundary survey may also help you identify whether you are located in a floodplain, which would mean you are required to obtain flood insurance. A boundary survey in Macon is also very helpful in completing the requirements for a mortgage loan from a lending institution, which includes checking the accuracy of the description of the property in the deed and the presence of improvements, easements, and any encroachments.

Boundary Survey Costs

The cost of a Macon boundary survey depends on several factors, some of which can only be determined once the work has begun. Some factors are size of the lot, the terrain, the vegetation type, the season of the year (which greatly affects the growth of vegetation). The work begins with the deed research that can be started with the deeds or abstracts that the landowner may possess and can extend as much as going to the courthouse and putting together the pieces of the deed. The job could get more complex if the property involved has been passed on through several owners over the years. Some may have sold off a portion of the parcel or may have added to adjacent lots. The more of these additions and subtractions can significantly impact the complexity of the work to be done, which consequently adds to the survey cost.

Boundary Survey Drawing

After the boundary survey is done, a landowner should expect to get a survey drawing that contains a sketch of the survey findings and the legal description of the property. It is also expected that proper markings of the property lines and corners have been placed, which are usually bright-colored ribbons or paint, wooden stakes, or concrete monuments. Others survey projects may or may not include a drawing or report, depending on the services agreed upon.

What is an ALTA Title Survey?

Posted on August 10, 2013 by MaconSurveyor

ALTA stands for American Land Title Association. ALTA Land Surveys are similar to a boundary or lot survey of a piece of land. However, an ALTA Title Survey has further requirements for the land surveyor as he executes the survey because of the high-dollar value of the property.

ALTA Survey Standards Lead to Consistency

Most states have widely varying standards for surveying. Thus, ALTA Surveys follow a national standard for surveying aimed to generate consistency regardless of the location of the survey. This type land survey is usually done on a multi-family residential or commercial site and when the owner and/or lender are from different states. But more often than not, it is prepared for commercial properties because it provides the information needed in order to insure the title to the land. Commercial developments may also require improvements to a high level that is also obtained through this survey.

ALTA Title Surveys are very complex and are commonly more costly than surveys following state standards because it takes more time and effort.

Costs for such surveys could be up to 50% – 200% more than a similar boundary survey. It is also important to note that the more restrictive standard is followed in the survey if the state standard is more restrictive on a certain aspect than the ALTA standard. An ALTA Title Survey must show all data including boundary lines, main building location and all its improvements, location of ancillary buildings, rights-of-way, and easements or access rights by utility services such as water, telephone, gas, railway and other utilities. A helpful tip in outlining the scope of services of the land surveyor is to thoroughly go over the elements of “Table A – Optional Survey Responsibilities and Specifications”.

ALTA Survey Requires Title Committment

Before an ALTA Title Survey can be completed, there must be a current title commitment. This is where the land surveyor will refer for the legal description of the property and all legal encumbrances or exceptions. The areas of ownership, encumbrances, and improvements will be presented graphically including encroachments, if there is any.

All the affected parties; the buyer, seller, lender, and title insurance company must be indicated on the ALTA Title Survey certificate. The land surveyor and the title insurance company must closely work together in order to illustrate comprehensively all matters affecting the ownership of the land and improvements.

Requirements for an ALTA/ACSM Land Title Survey as detailed by the American Land Title Association, National Society of Professional Surveyors and the American Congress on Surveying and Mapping is certainly met through an ALTA Title Survey.

The Basics of Land Surveying

Posted on July 19, 2013 by MaconSurveyor

What is Land Surveying?

Land Surveying dates back to ancient history. Surveying is used for multiple projects. A survey is done to establish a specific location of a parcel of land along with its exact acreage. It is used to ascertain boundaries for defining an area of ownership and tax liability. It is also used to identify a piece of property by a written legal description or to provide a review of the accuracy of an existing description. Data from land surveying is of the utmost importance with regard to buying and selling land, and is also used to insure a clean and marketable title.

Other types of Land Surveying

There are many different kinds of surveys that can be performed. B oundary surve y ing is typically done for undeveloped land. This type of land surveying measures the actual physical extent of the property in question. Most surveys progress through the basic procedures regardless of the type being done. Any pertinent deeds, contracts, maps or other documents that contain a description of the property’s boundaries are located, studied and interpreted. A determination is made of what the actual property description is deemed to be, along with the locations of any physical evidence of the boundaries. This can be in the form of both natural and man-made monuments or markers that exist in the field. The property is then measured to establish the boundaries, not only using the appropriate existing monuments but with the creation and referencing of new markers where necessary. Measurements are accomplished using a total station and other land surveying tools. A total station measures both vertical and horizontal angles, as used in triangulation networks. After these steps are accomplished, the property description and plat are prepared.

Results of land surveying

Interpreting the results of a land survey is not as difficult as it may first seem. For instance, a property plat will usually contain a directional orientation which is typically indicated with an arrow pointing north. It will contain the bearing and distance of each boundary line, the property lines of other properties shown on the plat, and the names of adjacent property owners listed in the areas of their property. Corner monuments, along with the names of any natural monuments (such as “Smith’s Creek”, for example) or a brief description of any unnamed natural monuments (such as the “30-inch pine tree”) are on the plat. There is also a title block containing the property’s location and name of owner, the surveyor’s name, the date the survey was performed, the scale of the plat and any other relevant data.

If you need the services of a surveyor for your land surveying needs, ALWAYS be sure that you’re hiring an experienced, certified, and highly competent professional surveyor. You can find out if the surveyor is licensed by visiting the Board of Licensure’s website.

Licensed Land Surveyor: Using GPS to Track You – Is It Real?

Posted on November 13, 2012 by MaconSurveyor

A licensed land surveyor trusts his GPS system like his gun in a battlefield. Though it sometimes do not provide all the info that you may need, it is nonetheless very helpful in producing an accurate boundary survey.

Many have heard of “Big Brother” being able to track our movements. One of my favorite TV shows is “Person of Interest” where a secret machine keeps track of all conversations and people’s “criminal intent” in order to help the heroes stop the crimes before they happen.

While I’m SURE that there are tracking capabilities in most cell phones and different government agencies CAN track our locations, we might be a ways away them being able to determine criminal intent. But there IS a recent application in England that I found very interesting.

Nestle (yes, the chocolate company) is placing GPS Trackers in six KIT KAT bars in their aptly named “We’ll Find You” marketing campaign in the UK. When the person opens the package it notifies KIT KAT and the prize delivery team will find them within 24 hours and present them with a check for £10,000 (about $16,000.) See the article here.

Just about all new type cell phones, all smart phones, iPads and other tablets, lots of cars (more than you think), public transportation vehicles, golf carts, and watches have GPS devices in them now days. Another place they are, and rightly so, are in ankle monitors used by law enforcement. But, what you might not realize is that the electronic devices mentioned above can work just like the ankle monitor. Now, while it is true that you can disable the GPS tracking device in your cell phone or tablet, that doesn’t give all of us complete comfort in walking around with these devices on us.

Now, I’m not trying to be a conspiracy wonk here, but it is POSSIBLE that this could be taken advantage of by well-meaning agencies. And, as we know, law enforcement can make mistakes in identifying the correct suspect. Of course, as a licensed land surveyor myself, I WANT emergency services to be able to find me if and when I need their service, so this is a double edged sword. Most of us probably have nothing to worry about in this regard, but if you worry about this sort of thing, it could keep you up at night.

Even as a licensed land surveyor, having used GPS technology in land surveying for almost 20 years, I still trust them more than I should.

One example is when I was in an unfamiliar town my GPS navigation device told me to take a “road” to the right. I slowed down and attempted to turn but it was a power line. Not wanting to believe that Gizell was wrong (yes I named her), I went to the next street and turned and tried to find the “road” further back. I ended up driving down the sandy power line, which turned into a bike lane until I was finally stopped by a gate. As I backed down the bike lane looking for a turn-around spot I thought, “maybe this wasn’t a road and maybe my GPS device is fallible.” Of course, I soon justified Gizell by recalling that a human had to “digitize” the roads in and she just did what they programmed her to do.

If you need to turn off your GPS tracking device in order to sleep tonight, call your device’s customer service line and stay away from KIT KAT bars. If you would like to find out how GPS surveying technology can help you in surveying your property boundary, call a Licensed Land Surveyor at Macon Surveying at (478) 845-6911.

Explanation of a Topo Surveyor

Posted on November 10, 2012 by MaconSurveyor

Topo Surveying and Topo Surveyor

A Topographic Surveyor also known as a Topo Surveyor collects the survey data to locate man-made and natural marks and its elevations on a particular portion of land. It normally comprises any man-made underground marks such as utility lines. It will also illustrate ground level installations such as utility poles, buildings, walls, and many other significant installations.

The utilization of standard topographic surveying procedures are commonly employed to provide accurate measured plan of terrain. It is also used during the mapping and graphing phases of projects to blueprint the locations and layout of the installations, road, buildings, and many other engineering and architectural projects in the construction industry.

Why Hire a Topo Surveyor?

The purpose of getting a Topo Surveyor to do topographic survey is to obtain an accurate trace and documentation of the present state of a parcel of land that will be constructed on; either a building, a wall, or any other construction activity. The design engineers make use of the topo survey as they plan the design and then the proposal of the final surface.

It is important to have this plan as this allows the Engineer compute, analyze, and estimate the amount of earth work that might be required. The Engineer will also be able to balance the amount of earth work to minimize the dirt to be taken off and on the construction site. The architect also makes use of the topo survey the same way as the Engineer does.

Additionally, the architect may plot the surface in 3D to picture out the finished look with the improvements he might add. This plot may be presented to the construction owner, building owner, or the land owner before the actual construction takes place. An accurate topo survey is of big help to ensure the installations and improvements fits in on the site within its boundaries.

Common Methods that a Topo Surveyor use

The two common methods of doing a topographic survey are Aerial Topo Survey and Conventional Topo Survey. How the topographic survey done would vary on the method the Topo Surveyor use. It is important that a topo surveyor know how to carry out both in any circumstances. So if you will need one, make sure he is professional and experienced both methods.

An Aerial Topographic Survey is done on the airspace. It is taken either in a helicopter or in an airplane at a defined distance above the ground level. Aerial photos of the ground surface are then taken and examined by the topo surveyor. This will allow him to envisage the ground surface through the structure of a stereo pair. By looking at the two overlapping aerial photos, the vantage points are determined.

A Conventional Topographic Survey is done when there is a need to get the accurate contour interval and spot elevations. The Aerial Topographic Survey is limited in the precise vertical and horizontal point location of the ground surface. These are just simplified elaboration of the two methods of topographic survey to provide you an overview. Read and research to learn in depth about them or ask a topo surveyor.

What Is A Land Surveyor?

Posted on November 9, 2012 by MaconSurveyor

A Land Surveyor is essential whenever you plan on building a house, buying or selling a property, or dividing your property amongst your children. Many land surveyor made it down to history. In fact, three of the four faces carved in Mt. Rushmore are land surveyors (Presidents George Washington, Thomas Jefferson and Abraham Lincoln were all three surveyors, Teddy Roosevelt was not.). Others popular names were Daniel Boone, Meriwether Lewis and William Clark (Lewis & Clark), Sir George Everest, Charles Mason & Jeremiah Dixon (of the Mason-Dixon Line fame) and author Henry David Thoreau practiced for a time in Concord, Massachusetts.

What is a Land Surveyor?

A land surveyor is a person with the academic qualifications and technical expertise to measure and plot the lengths and directions of boundary lines and the dimensions of any portion of the earth’s surface (including natural and other structures). That definition is quite a mouthful, but in actuality the field of surveying (geomatics) includes many other facets.

If you plan to purchase a lot, build your dream house, divide your property to your children, or simply want to know the details of a land property, a land surveyor is the best person to help you out. A land surveyor locates the boundary of your property and the location of your home within that boundary to determine if there are any encroachments by your neighbors onto you or vice versa. Common encroachments are fences, driveways, etc.

These days a land surveyor in the United States is regulated and licensed by the various state governments. In Alabama, the Alabama State Board of Licensure for Professional Engineers and Land Surveyors was established in 1935 to protect the public. A land surveyor’s duty is “to safeguard life, health, and property, and to promote the public welfare by providing for the licensing and regulation of persons in the practices of engineering and land surveying. This purpose is achieved through the establishment of minimum qualifications for entry into the professions of engineering and land surveying, through the adoption of rules defining and delineating unlawful or unethical conduct, and through swift and effective discipline for those individuals or entities who violate the applicable laws or rules.”

How to become a land surveyor?

As of 2007, a newly licensed land surveyor is required to finish a four year degree in surveying or a closely related field, a four to eight years of on-the-job training under a licensed practicing surveyor. In addition to that, licensed land surveyors are mandated to attend 15 hours of continuing education annually to ensure that they are kept updated with the new know-hows that would help them on their professional growth.

What does a land surveyor do?

As part of a standard lot or mortgage survey of a property, expect your land surveyor to review tax maps, aerial maps, deeds, subdivision plats, zoning ordinances, subdivision regulations and possibly even flood maps. For a typical lot survey, the subdivision plat is the most important of these because it tells the exact dimensions of your lot and the relative location of your property corners. The surveyor uses this to locate and/or re-establish your property corners.

In the field, a land surveyor will search for your property corners along with some of your neighbors’ corners. If yours can’t be found, they’ll measure the distances and angles between all of the points, locate the improvements on your property, including your house, pool, out-buildings, retaining walls, fences, driveways, sidewalks, and other home improvements. Other improvements like sanitary sewer mains, storm drainage ways, overhead power lines and the like are located because these might indicate an easement across the property. The plat should show these, but may not in all cases.

Once all of the field information is gathered, the crew chief takes the field notes and prepares a preliminary sketch of the work. This is passed along to a draftsperson who prepares the final outline for your use. The draftsperson will check all of the maps mentioned earlier to make sure that all building setback lines and easements are shown on the draft. The surveyed distances and directions are compared to the plat distances and directions as well. Any discrepancies or encroachments are shown on the drawing. Your lawyer may use the draft to determine if any other legal work is needed during the closing. The mortgage company or the bank may also use the survey for their records.

So now, what do you have for your money. You have a drawing which shows your house on your lot. You should have stakes and/or flagging by all of your property corners. Make sure you know where they are located. The actual corner is marked by an iron pin or pipe of some sort. (The type of monument should be shown in your survey drawing.) You might also want to take a look at them at least once a year to make sure they’re still there. (Even animals mark their territory more often than that.)

What You Need to Know About Land Surveying

Posted on November 8, 2012 by MaconSurveyor

What is Land Surveying?

Land surveying is the art and science of accurately measuring parcels of land. Measurements such as dimensions, lengths, boundary lines, including structures within the area are all precisely determined through a land survey. These measurements are used to establish land maps, boundaries for ownership or for governmental purposes. It is a detailed study of every physical and cultural property of the land, whether above or beneath it, to illustrate it in usable form.

Data is gathered through observations, research, field measurements, and data analysis for establishing property boundaries. Records from previous surveys and government records will strengthen the reports made after the survey.

What covers land surveying?

A land survey is classified according to the purpose or why the survey is being performed. Some of the common types of land survey are boundary surveys, topographic surveys, partition or subdivision surveys, flood elevation survey, property line adjustment survey, and extended title insurance coverage survey.

Other services such as mapping, construction layout surveys, judicial surveys, registered land surveys are all part of land surveying. It is an essential element in every development of the environment especially in the fields of construction, transport, communication, mapping, and most especially in the definition of legal boundaries for ownership.

The key component in the field of land surveying is the land surveyor. A land surveyor is a person that takes charge of every activity that transpires during a land survey. It is the surveyor who makes the research and data gathering and even interpretation and analysis of all data wherein translation of all data gathered is crucial and should be checked, attested, and sworn in the law to be true and correct. It is important then for you to choose a land surveyor with the highest degree of expertise and who can assume responsibility for the complex tasks at hand. It should be emphasized that only a surveyor who has knowledge of the elements of geometry, trigonometry, engineering, mathematics, physics, and the law are expected to have the best land survey outcomes.

Land surveying – dated back in history

Land surveying is a profession as old as the Egyptian times yet its importance to the human race still lives on. It is the best method to settle disputes over land ownership, it gives a clear picture of what buildings are suited to be constructed in a given land area, and it’s a convenient way to determine the exact dimensions of real estate to be purchased or sold.

Optimum potential of the land you own can only be defined once you have a land survey. Whether you are planning to put it on the market, or should you want to use it for commercial purposes, a land survey must back you up if ever questions regarding everything about the land arise. Land surveying will provide a sense of security and peace of mind to every land owner and even to the future buyers.

Land surveying will always be an integral part in protecting real estate and upholding of laws governing the utilization and distribution of your land assets.

Land Surveyor: Settling Land Disputes

Posted on November 5, 2012 by MaconSurveyor

A land surveyor may not be recognized as much as a doctor or a lawyer, but no one can dispute that they play a very crucial role on Earth.

As proof, several countries all over the world have unsettled land disputes over other countries. Some may have been settled through the International Court of Justice, Treaty conditions, or a claimant country’s sovereignty has been recognized. And of course, these were all settled with the help of a land surveyor.

Let’s take a look at some of the famous land disputes all over the world settle by a land surveyor:

Mayotte (Africa) – Claimants are France and Comoros. France gained full control under the 2009 referendum, the population supported an overseas department of France, and so became one on March 21, 2011.

Ligitan and Sipadan (Asia) – Claimants are Malaysia and Indonesia. The 2002 International Court of Justice ruling awarded both islands to Malaysia, but left unsettled the maritime boundary immediately southwest and west of the islands between Malaysia and Indonesia.

Eastern coast Narva and Petseri County (Europe) – Claimants are Russia and Estonia. Russia recognized them as a part of Estonia with Treaty of Tartu, 1920. After the fall of the Soviet Union, Russia continued administering it.

Tuzla Island and Strait of Kerch; Sarych (Europe) – Claimants are Ukraine and Russia. The conflict arose in 2003 when the Russiam authorities started to build a dam towards the island. Since then Ukraine established a border garrison on the island for a closer surveillance. The reason for the conflict is the fact that Tuzla island strategic location gives Ukraine full rights over the main channel in the Strait of Kerch and, this, the access to the Sea of Azov.

San Andres and Providencia (Central America/ Caribbean) – Claimants are Colombia and Nicaragua. Colombia currently has full control because Honduras de facto recognises Colombian claim.

Los Monjes Archipelago (South America) – Claimants are Venezuela and Colombia. Velenzuela gains full control because Colombia no longer claims the islands, only the surrounding water.

A piece of parcel is something that signifies power and resources thus many countries fight over it. If big countries have unsettled disputes over a piece of land, small land disputes also happen between siblings, husband and wife, and neighbors. Though you can’t hire a land surveyor from an International Court to settle your small land disputes, you can always hire a local land surveyor who can survey your property and resolve any encroachment claims and/or equally divide a property as mandated by law.

A land surveyor plays a very vital role in settling land disputes, big or small. If you are in a situation that you may need the expertise of a land surveyor, please contact Macon Land Surveying at (478) 845-6911 today or go to our Contact page and send us an email.

Land Surveyors: Leaving Their Marks

Posted on November 5, 2012 by MaconSurveyor

Men and women who combine their sense of adventure, their love of technology, and also their talents in making things happen with their desire to leave a lasting impression are the people who joined the ever expanding realm of land surveying.

Land surveying is likely one of the world's most vital occupations. It's the only job qualified to form new property boundaries. Moreover, land surveyors also play a significant part in the construction of incredible architectural accomplishments – from the historical achievements that are ages old to the impressive buildings today. As a matter of fact, three of the gents on Mount Rushmore are land surveyors themselves.

Geographic Information System or GIS experts and staff rely upon surveyors for mapping details. The task of your land surveyor has shaped the world as we know it; and it all starts off with small survey markers. It might be merely a small orange survey marker, but this mark is one of the millions that the surveyor uses to take detailed measurements that would become maps which will someday become amazing buildings, new roads, master planned communities, or entire cities – and in each step along the way is a surveyor.

Land surveyors specialize in many positions:

Photogrammetric surveying

In the Office, photogrammetric surveyors deal with cutting-edge software and state of the art machine.

Boundary Surveying

These are land surveyors who do in depth reference research studying maps and boundaries spanning centuries.

Construction Surveying

Within the area, construction land surveyors are the power behind any growth; these people team up with engineers to ensure that the structures are constructed within its area and coincide with the type of land where it's built on.

Hydrographic surveying

Hydrographic land surveyors take their work to the lake or sea, determining depths, borders, and a lot more. Geodesy involves surveying where you can acquire specific dimensions for satellite.

Land Surveyors may also find themselves inside the court room. They also perform a vital role in providing expert testimonies with regards to boundaries or even in assisting crime scene cases which involves land.

Qualifications of land surveyors

With merely a high school diploma, anyone can begin as land surveyors, an on the job training that would last for just six weeks, field training, and union apprenticeship. However, a lot of land surveyors are degree holders. Local community universities may offer programs or a two year comprehensive program in land surveying. Incomes tend to be greater than average career fields that need a 4 year college diploma or if these people acquire a degree or higher, they could begin management or one of the many specializations.

GPS and Land Surveying

Posted on November 1, 2012 by MaconSurveyor

Land surveying is a profession that greatly utilize the GPS system.

Today, man-made constellations are in orbit. Their purpose is to provide instant, exact and global positioning information. This global positioning system of GPS is revolutionizing the modern construction sites, automating and guiding land surveying equipment, providing instantaneous circles and volume gap, simplifying total and controlled surveys. Nearly everyone involved in the land surveying and construction industry has heard something about satellite positioning technology or maybe you or someone you know is already using it. Whether an operator or a casual observer, there are still many questions about how this exciting system really works.

These positioning satellites don’t stay in one place like the stars; they orbit the earth about twice a day. Constantly transmitting uniquely identified radio signals that can be perceived by specialized units on earth. These signals are used to precisely measure the distance to the receiving instrument from each satellite visibly overhead.

Just as stars have exact locations in the sky, the locations of the GPS satellites are also defined, becoming orbiting reference points. Using a process based on triangulation, a GPS receiver processes the signals from multiple satellites to compute an accurate position on Earth, which is why it is widely use in land surveying.

For mobile applications that require high accuracy, such as three dimensional machine control, there are two requirements that must be met. First, the signals from a minimum of five satellites must be received at all times. And second, those five satellites must be distributed across the sky. This is called Dilution of Precision or DOP. The simple rule of thumb is this, the more satellites received the better your system will perform.

All land surveying receivers incorporate standard GPS tracking technology; unfortunately the GPS satellite constellation alone cannot continuously make the minimum requirement of accurate mobile positioning. For any given location, there are times in a day when there are less than five available satellites or very poor DOP.

Now, consider a land surveying job site with trees, buildings, or other obstructions when satellite receptions are easily be further reduced. All land surveying GPS receivers suffer this same problem because they all use the same satellites to operate.

Even the planned signal modernization to the GPS satellites won’t solve this problem. An obstruction that blocks one signal blocks all signals from that satellite. A land surveying equipment provider has solved this problem. The solution isn’t adding more signals from the same satellites; it’s adding more satellites.

Today, there is a second positioning satellite constellation in operation, the Glonass System. This positioning system is operated and maintained by the Russian government; much like the GPS is operated and maintained by the United States government; combining these two satellite constellations give land surveyors access to 38 different satellites; 14 more than a GPS-only system.

The additional satellites mean stronger and more accurate positions and better performance in obstructed land surveying areas. These additional satellites mean maximum up time in all land surveying locations, in all conditions.
