(Applicable for Aerial Stereo Photos, Satellite Stereo Images and UAV/Drone Stereo Photography)
Aero-Triangulation
Aerial triangulation techniques are used to improve the accuracy of the INS/GNSS/IMU data of aerial images and positional sensor/orbital data of satellite images with the help of accurate ground control points collected by various survey methods. In combination with a minimum number of ground control points and adjoining matching image Tie Points, aerial triangulation delivers best fitting results on the ground for entire block of images. As shown in the image, the entire area’s Aerial images are geo referenced with respect to some known Ground Control Points (GCPs). Only after this process the 3D measurement of the feature and terrain can be performed
Orthophoto Generation
WET specializes in high-resolution orthophoto imagery production. An orthophoto is an aerial photograph/satellite imagery that has been geometrically corrected or ‘ortho-rectified’ such that the scale of the photograph is uniform. An aerial or satellite image is rectified with the terrain data to correct the lean and distortion due to terrain relief, and camera tilt and orientation. This process makes scale of the image uniform. All such adjoining images then mosaicked through the overlap area with the help of seam lines to make it seamless and color balanced both in terms of geometry and radiometry features. An orthophoto is utilised in the same manner as a map of a particular scale.

3D Vector Mapping / Planimetric mapping
3D Planimetric/Topographic mapping mainly represents the earth surface features with height elevation from the datum as Point/Symbol/Nodes, line/Polylines and Polygon/region data. With such data user can make different analysis and decisions based on their specific need and applications of feature like building outline, building ridge line, building highest elevation, roads, ditches, drains, bridges, ponds, rivers, dam, vegetation, trees, utility poles, manhole, catch basin etc.
DTM / DEM / DSM (Digital Surface Model)
Data collection for creation of the Digital Terrain Model (DTM), Digital Surface Model (DSM), and Digital City Model (DCM) etc. is made by 3D data extraction from stereo pairs as a set of points, line and polygon data. Sometime it is a collection of discrete elevation points at regularly spaced intervals. The model reflects abrupt changes in relief such as incised streams, ridge lines, and slope breaks. Digital elevation models are used as the basis for the elevation representation by contour lines and height spots on topographic maps. It is also one of the input items for making a digital orthophoto.
It can be extracted by employing different methods and strategies like Automatic, Semi-automatic and Manual terrain extraction with surface features and without surface features etc. from aerial stereo images. Further it is used in various spatial analysis and algebra of the terrain depending on the requirements like cut and fill, slope and aspect, hill shade analysis etc.
