GPS Datum
Thursday, January 22, 2009
At Anglia Land Surveys (ALS) we have been providing our GPS surveying services since 1976 and have grown to become one of the leading surveying companies in East Anglia. Using GPS RTK units we are able to collect huge volumes of data in a relatively fast time and at competitive prices.GPS Datum is a maths model which represents a portion of the Earth's surface. Lines of latitude and longitude drawn across paper maps can be referenced to a specific map datum. The positional information gathered can then be gathered on a GPS receiver, so long as the map datum selected on the receiver corresponds to the datum listed on the paper version.
One important aspect of GPS datum is in the production of flood risk assessments for submission to the Environment Agency during the planning process. Using datum technology we can overlay level information from the GPS onto existing Ordnance survey mapping, which also allows us to add contours and show the site relative to local flood zones as identified by the Environment Agency.
For more information on GPS datum levelling and the other GPS surveying services please take a look through the rest of the website and don't hesitate to contact us with any questions.
