Land Surveying Uses GPS

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

ladn surveyingToday, 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.

land surveyingFor 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.

Topo Surveyors Make Topographic Maps

Topo Surveying and Topo Surveyor

topo surveyorA 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. The topo surveyor normally includes any man-made underground marks such as utility lines, if they are marked in advance. It will also illustrate ground level installations such as utility poles, buildings, walls, and many other significant improvements.

The utilization of standard topographic surveying procedures (not those shown in this image) are commonly employed to provide a precisely measured plan of the terrain. This method also includes the mapping and drawing phases of projects to document the locations and layout of the improvements, 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 a topographic survey is to obtain an accurate map 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 proposed final surface.

It is important to have this plan as this allows the Engineer to compute, analyze, and estimate the amount of earthwork 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 or onto the construction site. An architect may also make use of the topo survey the same way as the Engineer.

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

Common Methods that a Topo Surveyor use

topo surveyorThe two common methods of doing a topographic survey are Aerial Topo Survey and Ground Based Topo Survey. How the topographic survey is done would vary depending on the size of the project and the contour interval desired. It is important that a topo surveyor understand how to carry out both in any circumstances. Choosing the proper method, based on the project requirements is an important decision that the topo surveyor should be able to help with. Having been involved in both types of topo surveys will allow the topo surveyor to make use of the most appropriate method.

An Aerial Topographic Survey is done from a point above the ground surface using either a plane, helicopter, un-manned aerial vehicle, or a crane to get the aerial camera above the ground.  The distance above the ground is determined by the precision needed for the topo survey. Aerial photos of the ground surface are then taken and examined by a photogrammetrists who does the mapping from these stereo pairs of photos. By looking at the two overlapping aerial photos, the improvements and breaklines are gathered.

A Ground Based or Conventional Topographic Survey is done when there is a need to get more precise contours and spot elevations or if the site is small.  The Aerial Topographic Survey is limited in the precise vertical and horizontal point location on the ground surface. This a somewhat simplified discussion of the two methods of completing a topographic survey. While this is an overview, you should read and research more if you desire to learn in depth about topographic surveys. Or, just talk to a topo surveyor.

Land Surveyors: Leaving Their Marks

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 surveyorsLand 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 accomplishmentsfrom 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 land 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 land surveyors use 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 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 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 a surveyor, 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.

What Is A Land Surveyor?

land surveyorA 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.)

The Essence of Land Surveying

According to research, land surveying has existed ever since the beginning of recorded history. They believe that it has long been used in making the great pyramids; in which historians believe to be very accurate in the calculation of its land area. It was also used in ancient Egypt in re-establishing lost land boundary markers whenever Nile River overflowed its banks. Finally, historians believe that prominent people back then created this land surveying practice in order to have refined sharing of the lands they own.

land surveyingAlso, there are verses in the Bible that support the practice of land surveying

  •  Proverbs 22:28 Do not move the ancient boundary, which your fathers have set. 
  •  Deuteronomy 19:14 "You shall not move your neighbor's boundary mark, which the ancestors have set, in your inheritance which you will inherit in the land that the Lord your God gives you to possess.
  • Deuteronomy 27:17 'Cursed is he who moves his neighbor's boundary mark.' And all the people shall say, 'Amen.' 

Now what does land surveying really mean?

Land surveying basically means measuring and mapping lands. It is the science of accurately calculating the land’s area; determining the points of distance between a land and another. The actual purpose of this is to establish land maps and set boundaries for ownership. It is commonly used in the execution of nearly every form of construction.  The system of land surveying has proved itself to be a very important factor in the development of human environment as the earth’s surface continues to change according to the lifestyle of people.

land surveyingJust imagine a world where people freely claim an area of land for their benefit without even thinking of the others. Imagine people crossing over another person’s land because there are no borders that would express the ownership of anyone. Imagine people building any construction they want in any land they prefer. Or just simply imagine your neighbors removing your fences. If this happens, it would lead to chaos. That is why land surveying has been made to follow.

The importance of land surveying is identical to its purpose. It is responsible in the establishment of the maps of every city, region, country, continent or the earth itself. Through this system, there would be definite borders blocking any people from owning what another person owns. With this procedure, the distribution of the vast space of land would be fair enough. Everything would be organized and regulated.  This would mean that the buildings, railroads and even our houses would be made without having any complications.

As you can see in books, magazines, websites and other things that contain information about our world’s structure, we can see that there are boundaries which separate one place from another. This diminishes the complications in the ownership of lands among people. Since humans tend to get selfish, it is best to have everything in order, up to the issue of allocating land areas for everyone. This is the real essence of land surveying.

Things to Know When Building Your House

Land Surveying in Building your house

land surveyingIt is a very good idea to build your home because you will be able to get exactly what you want instead of when you buy. Of course, you may need to add some things or you may not know what you are getting yourself into.

It is a huge decision choosing the right builder since it is one of the largest personal investments that you will make. Be sure to give an interview to all of the possible contractors and then pick the one that will help make your dream home come true. While you are talking to the possible contractors be sure you ask all of the pertinent questions that will help you choose the best; their how long they have been in the business, experience,  what are the kind of buildings that they have experience building and it would be great if you can see some of their work. It is also crucial to pick house plans which may lead to a good home now and in the future. This is something that your contractor should be able to help you with and they may call on the services of an architect.

Budget in building your house

Before to planning your house design consider these factors; your budget, the size of the home to be built, location of the home, wall finishes, design features that you would like, ceiling height, number of stories, fixture types, exterior finishings, also your time frame. 

If you happen to be uncertain about any of these items, your contractor or architect should be able to guide you through this very important process. They will help you choose the details that are right for you down to the very smallest detail. They may refer you to other consultants for things like finishes, colors, and the like so be prepared to sit and discuss with them for a few hours to talk about all these choices that you may have.This is the reason that your choice of a builder is important. 

If your builder isn't able to advise you on home location they should refer you to a real estate agent. A real estate agent is familiar with important details like neighborhood home values, school districts, traffic issues, funding options, etc.

Land Surveying: avoids future problems

Another stop you should make is to see a land surveyor. Land surveyors are trained and experienced in identifying features of the land that might have an impact on your new home – called land surveying. Some of these features are flood zones, property line encroachments from neighbors, lot dimensions, and building setbacks. Land surveyors are measurement experts. And, since your home is your most valuable asset, land surveying should be one of your first steps in any new construction.

What You Need to Know About Land Surveying

What is Land Surveying?

land surveyingLand 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 surveyingLand 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.

The Basics of Land Surveying


land surveying

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. Boundary surveying is typically done for undeveloped land. This type of survey 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.

How To Find Your Home On FEMA’s Flood Insurance Rate Maps

What is are FEMA flood maps?

flood mapsFEMA's Flood Insurance Rate Maps (FIRMs) or just Flood Maps are provided after a flood risk assessment has been completed or updated for a community.  This study is known as a Flood Insurance Study.  The FIRM gives you the Base Flood Elevations (BFEs) and insurance risk zones in addition to floodplain boundaries.  The FIRM may also show a delineation of the regulatory floodway. 

Once the "insurance risk zone"  (commonly referred to as the flood zone) is determined, actuarial rates, based on these risk zones, are then applied for newly constructed, substantially approved, and substantially damaged buildings.  FEMA uses these rates to determine the insurance rate you will pay for flood insurance

FEMA's Digital Flood Maps

FEMA discontinued the production and distribution of paper flood maps in 2009 as part of its Digital Vision Initiative. This affected all the Flood Maps, boundary information, and study reports. However, clients can still view the products for free through their website or buy them in digital format.

To view these flood maps online, go to FEMA's Map Service Center and key in your address (hi-lited area shown here) search for your home.  This will prompt you to then select the map that covers your area.  The Flood Maps are somewhat cumbersome to use online. It is best to go through the tutorial on the bottom right of the address search page for an easier and more effective use of the GIS map.

Enterprise Flood Maps by FEMA

If you are located in the City of Montgomery, you might also want to check the Enterprise Interactive GIS maps for more information and a little easier interface. Check the FEMA Flood Insurance Rate Map box on the left to view the flood zones on this map.

Call Enterprise Land Surveying at  (888) 936-8426 or  contact us if you need help with this process or if you discover you are near a flood zone and need an elevation survey completed.  We are here to help you minimize your flooding risk.
