Land Surveyors: Leaving Their Marks

Mobile Land Surveying Posted on September 15, 2017 by MobileSurveyorMarch 4, 2019

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 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 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.

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

Mobile Land Surveying Posted on August 6, 2017 by MobileSurveyorMarch 4, 2019

FEMA’s Flood Insurance Rate Maps (FIRMs) are issued after a flood risk assessment has been completed or updated for a community.  This study is known as a Flood Insurance Study.  The FIRM shows 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.

To view these maps online, go to FEMA’s Map Service Center and enter your address (hi-lited area shown here) search for your home.  This will allow you to then select the map that covers your area.  The Flood Maps are somewhat cumbersome to use online. I suggest going through the tutorial on the bottom right of the address search page in order to learn how to maneuver around in this GIS map.

If you are located in the City of Mobile, you might also check out the Mobile 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 Brandon Bailey, PLS at (251) 281-2081 or better yet send us a contact form request 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.

Land Surveying and GPS

Mobile Land Surveying Posted on June 18, 2017 by MobileSurveyorMarch 4, 2019

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

land 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.

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.

land surveyingAll 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.
