Preliminary works include creating 3D network of points tied with the geodetic network at a first or second order accuracy level by using GPS.
Based on the aforementioned points, the topographic setting out is undertaken using GPS or Total Station techniques as required and this includes:
1- Contour lines
2- Digital Terrain Model (DTM), Digital Elevation Model (DEM)
3- Setting out all geographic features on the earth such as roads, buildings, electricity lines, sewage
and etc ..
1-Showing premises’ border
2-Eliminating any dispute between neighbouring premises
