We provide multiple aerial triangulation services that are necessary for improving the spatial orientation aerial imagery. This process ultimately provides exterior orientation parameters for photographs and accurate three-dimensional co-ordinates for measured object points
We follow highly automated aero triangulation approach that minimizes the manual intervention and increases accuracy towards higher side.
DIGITAL ELEVATION AND TERRAIN MODELING (DEM/DTM)
Digital Elevation Models (DEM) uses grid pattern to define the surface, this enables us to show the changes in elevation in a smooth and progressive sort
A Digital Terrain Model (DTM) is a DEM in which terrain data has been further enhanced using breaklines and data points
We create the DTM and DEM data sets according to the requirement of the clients using dominant tools
We creates high quality Digital Elevation Models (DEMs) to support specialized applications such as 3D modeling, volumetric calculations, powerline surveys, Hydrology studies etc.
We generates fully detailed Digital Terrain Models (DTMs) for contour generation, orthophoto rectification, and other GIS applications.
PLANIMETRIC MAPPING
The objective of Planimetric mapping is preparation of base map for different applications with complete, accurate and correct feature coded data set in full compliance to the client specification.
We capture 3D features data from small to large scale stereo models and generate contours & digital topographic maps of high precision.
We implement extensive stereo-data compilation skills, combined with customized tools, providing excellent accuracy, completeness and correct coding of digital vector data.
Typical features collected on various scales includes Roadway elements, Driveway elements, Parking surfaces, Structures, Tree lines and landmark single trees, Major Hydrographic features, Major Utilities.
We provide the collected Planimetric data in a wide range of industry standard output formats.
LARGE SCALE MAPPING USING HIGH RESOLUTION SATELLITE DATA
High-resolution satellite imagery, namely IKONOS, QUICK BIRD, Land sat TM, and CARTOSAT were used successfully to update existing large-scale soil and topographic maps, drainage network, road network, Update large-scale land cover/ land use inventory, monitoring of permanent crops and Urban Planning
