SaraniaSat CANEUS Photogrammetry Data Products

Our image processing techniques improve the quality and utility of raw satellite/ drone imagery to generate actionable information from desired Regions of Interest for your business. We use high accuracy Digital Elevation Models (DEMs) to minimize geometric errors.

These images explain the importance of Orthorectification.

Planimetrically correct road after Orthorectification

All remote-sensing imagery, whether it is obtained from airborne or space-based platforms, contain distortions caused by

  • The camera viewing angle, particularly for off-nadir imagery.
  • Camera motion and vibrations.
  • Topographic variations in the observed terrain.

Our Orthorectification process involves the use of Advanced Rational Functions (RPC) based orthorectification including block RPC corrections to remove the effects of image perspective (tilt) and relief (terrain) and produce output images that are planimetrically correct to uniformly scaled.

Benefits of Orthorectification

Key Features :

  • Precise Geolocation: As-acquired, unreferenced imagery is accurately mapped to the correct geographical coordinates on the earth’s surface.
  • Mosaics: Stitch separate, overlapping images into seamless, large-area mosaicked images at desired spatial resolutions.
  • Maximize Efficiency of your operations: We eliminate your burden of producing photogrammetrically accurate images.
  • Cost Effective Solutions: SaraniaSat CANEUS’ high-value, photogrammetry core competency significantly reduces your overall project costs.

Urban and Local Planning:

SaraniaSat CANEUS provides high accuracy geospatial layers derived from drone/satellite imagery for specific management information of assets such as buildings, roads, parks and other utilities

Photo Mapping:

Mapping/Surveying organizations can avoid the expense of acquiring and analyzing customized survey data by directly using our Orthorectified images with accurate feature collection as the inputs for their mapping needs.

3D Modelling:
  • Virtual flight products: SaraniaSat CANEUS can generate 3D animations simulating a fly-through of a Region of Interest with topographically accurate features.
  • Our 3D Models provide useful and accurate insights for planning purposes in transportation, energy, and natural resource exploration and exploitation.

Our Orthorectification process involves the use of Advanced Rational Functions (RPC) based orthorectification including block RPC corrections to remove the effects of image perspective (tilt) and relief (terrain) and produce output images that are planimetrically correct to uniformly scaled.

Key Features :

Digital Elevation Model (DEM) and Contour Generation for modelling water flow, creating relief maps, rendering of 3D visualizations.

Image/Sensor fusion: We seamlessly fuse imagery from multiple sources, not only with different spatial resolutions, but also combine different sensing modalities such as synthetic aperture radar and multi-spectral optical imagery.

Color Compounding: We generate both natural color and false color images to aid accurate, quantitative analysis of the attributes of interest.
