PHOTOGRAMMETRY & LiDAR

ORTHOMOSAIC

A rectified and geometrically corrected image composed of all the aerial images taken during a photogrammetric mission. We achieve any desired GSD from 1 cm/pixel onward.

DEM or DSM

Digital files that contain elevation information of the terrain. DEM ofr DSM’s contain everything that’s on the terrain such as vehicles, buildings, trees and other elements which are not desirable for contour generation.

DTM

This file is similar to a DSM, with the difference that it contains only terrain data, tres, buildings and other artifacts are filtered out to obtain just bare earth data. DTM’s are ideal for contour generation.

CONTOURS

Lines that connect points with the same elevation. We can create contour with intervals as detailed as 25 cm.

POINT CLOUD

3D point data that contain XYZ information as well as RGB data. These points can be classified in different classes such as vegetation, buildings, bare earth, water among others.
