Photogrammetric Mapping

PHOTOGRAMMETRIC MAPPING (UAV / Aerial / Satellite Imagery)

At Dhatri Geotech Private Limited, we offer cutting-edge photogrammetry mapping services using UAV, Aerial and High resolution Satellite Imagery that provide accurate and detailed geospatial data for a wide range of applications for various industries.

OUR PHOTOGRAMMETRY MAPPING PROCESS:

AERIAL TRIANGULATION:

• 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) and Digital Terrain Models (DTM) are digital representations of the Earth’s surface. 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 create high quality Digital Elevation Models (DEMs) to support specialized applications such as 3D modeling, volumetric calculations, powerline surveys, Hydrology studies etc.
• We generate fully detailed Digital Terrain Models (DTMs) for contour generation, orthophoto rectification, and other GIS applications.

PLANIMETRIC MAPPING:

• At Dhatri Geotech Private Limited, we offer comprehensive and accurate planimetric mapping services that empower businesses and organizations with precise spatial data. Our experienced team of geospatial experts leverages cutting-edge technology and industry best practices to deliver high-quality planimetric maps tailored to your specific needs.
• 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.
