The purpose of a topographic survey is to produce a three dimensional drawing of a particular piece of land or area. Topographical surveys should include all natural and man-made features which are represented by text, lines and symbols on the drawing. The drawing should also include heights and elevations which are represented by spot levels and contours generated at predetermined intervals.
GeoSiam use a combination of high precision GPS, Total Station and Laser Scanning to undertake topographic surveys. Survey information is processed through dedicated mapping software to produce the required outputs. Drawings can be supplied in any coordinate system and multiple scales depending on the site conditions and client requirements.
