Photogrammetry:

Using highly efficient technological apparatus we are able to meet the specifications of our clients with precision. Dale with a staff of professional technicians and Photogrammetric Experts deliver products and quality services with exceptional competence.

Our Photogrammetric Services:

  • Aerial Triangulation
  • Softcopy Stereo Compilation (Planimetric/Vector Feature Extraction)
  • Digital Elevation/Terrain Modeling
  • Map Editing.

Aerial Triangulation:

  • Automated and Manual Aerial Triangulation methods are available.
  • Manual Aerial Triangulation processing is preferred for its higher accuracy.
  • We provide the clients with detailed triangulation reports of results and error analysis.
  • A root mean square (RMS) error of less than [1/10,000 times flying height] is typical.

Planimetric Mapping:

Planimetric/Topographic mapping is used in representing the features of the earth's surface in three dimensions (3-D). We use Line String, Line, Point/Symbol and Polygon/region data for this representation. Our experts collect Digital Topographic and Planimetric features interactively and most of these features are collected with a definite elevation, which in turn are used in the process of generating contour (a part of the Digital Terrain Modeling).

Typical features collected at 1"=50' scale:
  • All roadways including curb and gutter
  • All driveways paved and unpaved
  • All parking surfaces and paint markings
  • All structures
  • All vegetation including landscape shrubbery and trees
  • All hydrographic features including manholes, catch basins, valves etc.
  • All utilities such as power poles, light post, guy wire etc.
Typical features collected at 1"=100'scale:
  • Roadways
  • Driveways
  • Parking Surfaces
  • Structures
  • Tree lines and landmark single trees
  • Major Hydrographic features
  • Major Utilities

Digital Elevation and Terrain Modeling (DEM/DTM):

To show the accurate representation of surface features and elevations on the earth's surface we use DTM and DEM tools. We collect the DTM and DEM data sets according to the requirement of the clients. We use dominant tools in generating automatic and advanced contours. In DTM Models, to show accurate changes in elevation we use break lines and data points. These models define the surface in an irregular spacing pattern. DEM Models uses grid pattern to define the surface. This enables us to show the changes in elevation in a smooth and progressive sort. These are basically used in Ortho-Rectification process, Contours generation and also in GIS applications. Precise depiction of terrain is significant as it is very much useful for Volumetric and TIN calculations.

Map Editing

Dale delivers ingenious layout and design of the map sheet. With advanced contour interpolation, Processes like Cartographic editing, Planimetric data cleaning and its topological structuring and many are available.

Ortho Photography

Digital OrthoPhotography:


Using highly efficient technological apparatus we are able to meet the specifications of our clients with precision. Dale with a staff of professional technicians and Ortho Experts deliver products and quality services with exceptional competence.


Our Orthophoto Production services:

Ortho-mosaicing, Color Balancing, Seamline editing and Tile cutting.


Using computerized aerial/satellite imagery and making corrections through digital image processing for positioning of all ground features on the maps along the earth-referenced coordinate system, is called Digital orthophotography. Associated with CAD & GIS software systems, Digital orthophotography is a prominent tool in producing accurate measurements.


We use photogrammetric software on our High Powered Digital Workstations in performing Orthorectification processes.

We use adept image editing software for Radiometric alterations and modifications in the images and finally present the output in many formats including TFW, MrSid, JPEG2000, ECW etc.
