Topographic Survey/Volumetrics

Geotechnology carries out its topographic surveys in-house, using total stations and a differential GPS system. Different sites demand different survey techniques, so our ability to offer conventional survey as well as dGPS allows all sites to be accommodated. We are even able to offer traverse levelling using dumpy levels or spinning lasers. We are experienced in carrying out topographic surveys for microgravity surveys, where precise elevation determination is a fundamental part of the reliability of the data.

3-D datasets are acquired and then input into our specialist software to generate digital terrain models. The data allows us to produce conventional topographic plans as well as undertaking volume assessments. We carry out this service frequently for quarrying and landfill companies wishing to calculate stockpile or void volumes.
