Digital Photogrammetry servicess

AABSyS’s high-precision photogrammetric services are offered at extremely rational prices that make us competitive among the other photogrammetry service providers in domestic and international markets. AABSyS’s services allow accurate and cost-effective data collection for planning and designing of photogrammetric projects.

AABSyS provides complete solutions for all standard tasks in digital photogrammetry services. AABSyS typical services includes aerial triangulation, DEM / DTM generation, stereo compilation, topographic and Planimetric feature extraction, orthophoto production, color balancing, mosaicking and tile generation, contour generation, 3D terrain visualization, and orthophotography services.

Please find Photogrammetry service details below.

Aerial Triangulation:
Aerial Triangulation is the calculation of true ground co-ordinates, used as the base reference in photogrammetry.

Aerial Triangulation (AT) is an essential part of any successful photogrammetry project. AABSyS offers complete softcopy aerial triangulation services, providing highly accurate control for the map production. Digital images are uploaded into softcopy workstations. The airborne GPS coordinates and the ground survey control points are used to control the triangulation solution.

Digital Elevation Model:
Digital elevation model (DEM) is a representation of the Earth's relief used for geospatial analysis and modeling. Elevation data are captured in the form of points with defined interval and the Break lines. AABSyS is having tons of experience in the creation of TIN Models and elevation models from the DEM data Contours.

Vector Mapping:
Vector Mapping is a representation of the Earth surface features in 3D manner and used for geospatial analysis and modeling. AABSyS offers the preparation of map by extracting the vector or point information of railroads, buildings, hydrological features, vegetation, etc., as required by the user by different Symbols (trees, wells, poles, etc.,), Linetypes (rail, road, streams, etc.,) and Regions (buildings, tanks, forest, etc.,) with unique ID.

Ortho Photo Generation:
Digital Orthophoto is a raster image generated by differentially rectifying scanned aerial photographs to compensate for distortions due to the altitude of the aircraft and the relief of the terrain. Digital Ortho photos combine the image characteristics of a photograph with geometric qualities of a map.

3D Modeling:
Using 3D Modeling and virtual reality techniques, AABSyS is able to completely represent your real world, bringing together all the relevant aspects of the 3D environment that you wish to model.

Our key functions include 3D visualization, 3D environment modeling, true 3D landscape reconstruction, visual reality and virtual reality integration, real time roaming with huge amounts of data.

LiDAR Data Processing:
AABSyS provides turn-key LIDAR imaging services: aircraft, digital orthophoto and various topographic mapping products, including:

• Point clouds file (ground, canopy and intensity)
• Power line mapping and transmission line survey
• Contour mapping and topo maps
• Fusion with digital orthophoto or hyperspectral imagery
• 3D modeling and volumetric calculation
