The model of zero state measurement is devoid of generalization, while it clearly represents the lines of continuity of the terrain.

A detailed and accurate inventory of the height of terrain provides a correct (realistic) balance of earthworks at the start of the construction works and can be used at the stage of:

– design – as a base numerical terrain model

– cost estimation – for the purpose of offering investment realization

– taking over the construction site before the start of the investment, in order to secure the investor and the contractor

– comparison of the construction site with the design documentation (even before the cutting of greenery and demolition of buildings)

– periodic billing of construction works

We acquire data to build the model using aerial techniques in a very short time for large areas.
