Topographic Maps delineate contours for purposes such as highway construction, erosion management, inventory calculation and many others.

3D Elevation Data is derived from traditional photogrammetric processes as well as from new sensing technologies such as LiDAR. With LiDAR, Optimal Geomatic delivers complete surface data including digital elevation models, digital terrain models, contours, and triangulated irregular networks -- all from a single product. To enhance the information contained in a LiDAR terrain model, a digital ortho photo can be draped over the terrain model to provide the 3D effect that many clients need.
