GPS (Global Positioning System) Surveys
The benefits of using GPS equipment mean that it has now become a standard format in surveying due to its speed and effectiveness. Using GPS ensures highly accurate data capture along with the ability to cover large tracts of open land quickly, saving on cost and time.
Using a global network of satellites our receiver/transmitter is able to lock on and provide accurate data, due to a continually transmitting satellite signal that enables the receiver to calculate its 3 dimensional position (latitude, longitude and altitude), giving extremely accurate ground level locations. This information can be de-coded and exported directly into CAD applications.
Further to this, Ordnance Survey no longer updates and calibrates the local benchmark network making GPS the only reliable way of relating survey levels and heights back to ordnance datum, which is imperative for Flood Risk Assessment along with the majority of planning applications. Powers & Tiltman are able to provide you with reliable coordinates and level datum from the Ordnance Survey active GPS network to assist you with any height issues on your land.
GPS equipment used by Powers & Tiltman is controlled and used by one person making the process quicker and more cost effective for you. In many cases one team member will work on our GPS equipment picking up heights and levels alongside another team picking up boundaries and features. Your survey is instantly locked onto an ordnance Survey grid and large areas of land can be surveyed at exceptional but accurate speed.
The benefits of using GPS Surveys are:
- Compared to conventional techniques there are far fewer operational limitations.
- A greater accuracy of positioning physical features over large areas that can be utilised in maps and models.
- This is a faster, less labour intensive and more cost effective way of capturing data than other techniques.
Frequently Asked Questions:
(1) What is a GPS Survey?
A GPS survey is a method of utilising satellites and an internet connection to ensure surveys are linked to ordnance survey grid and level.
(2) How accurate is a GPS survey?
A GPS survey is very accurate in all 3 dimensions and can help to solve boundary disputes by generating a drawing which overlay directly on to ordnance survey plans.
