4. Topographical

Topographical survey involves the generation of contours and also the production of Digital Terrain Models.  Such services are required by engineers and designers to help calculate volume for earthworks (cut and fill).  With the advent of computer technology most of our clients require data in digital format, usually ASCII and MOSS.

5. Digital Mobile Mapping

-  Digital Video Mapping

-  Light Detection and Ranging(LIDAR)

6. Aerial Photogrammetry

Photogrammetric surveys are employed to help identify the general topography of the area of investigation before one engages the field survey units.  It is also used now to gather the latest ground information for the compilation of GIS data.  Photo mosaics produced help identify routes for new highways, transmission lines, gas pipelines etc.  This method can ensure that the designed route will not pass over residential areas, sites of sensitive nature such as cemeteries, schools and historical sites.  Photogrammetry will only be cost effective if the area of coverage is very large.
