<p>Present invention provides use of GPS for the purpose of surveying. GPS Satellites provide longitude, latitude, and elevation of a point on earth via a GPS receiver. We will mount a GPS receiver on a rover, which will follow a defined path on the site and will take GPS readings. Latitude, longitude data will be used to form survey grid and elevation will generate topography. The rover will transmit the data wirelessly to a ground station, where the data will be directly fed to REVIT ARCHITECTURE CAD software through an API (Application process interface). Now we will directly get 3D Toposurface of site area. The invention is described by way of example with reference to the following drawings where figure 1 showing A survey rover mounted with GPS receiver, figure 2 showing A receiver antenna at the base station, figure 3 showing A grid system with coordinates.</p> |
