Digital terrain modeling

Volumetric calculations of mass excavation and fill call for an organized approach to the surveying and the production of a digital terrain model. It is more involved than just taking levels at fixed intervals, breaks must be defined, overall boundaries marked out and edges surveyed. The formation of the model must take all these factors into account in order to accurately determine the volumes concerned, otherwise costly mistakes can be made.

Using total stations, GPS receivers and digital levels , we are able to model a terrain of any size anywhere in the world to a high degree of accuracy. Transferring electronically recorded field data into the computer and using sophisticated modeling software enables the speedy production of plans, perspective views and volumes. Additional analysis can be carried out as required along with routine longitudinal sections and cross sections.

Earthworks design and setting out for Landscaping are straightforward with digital terrain modeling techniques.
