Photo & ALS Control are points selected &/or placed on the ground, then coordinated by precise GPS measurements. These control points are then used to tie together the Photogrammetric and/or ALS data and provide reliable ground truthing to the large scale imagery and data sets. This is proven, state of the art technology and provides a more cost effective solution with less impact on the environment for larger scale projects.
A Terrain model is a 3D digital model illustrating the rise & fall of the land. A terrain model is typically extracted from the results of a Topographic Survey or compiled from existing records provided by local and state government authorities. The terrain model can be used for planning & design, for mapping & management of overland flow through to detailed engineering design & cut/fill calculations on developments.
