IMAGERY SERVICES

GSI provides image processing services to create and update geographic datasets for a variety of end users. These range from land use planning, utility planning, urban and rural infrastructure planning using high resolution imagery to forest mapping, watershed management, natural resource mapping, and mineral mapping using low resolution imagery.

Our imagery services include image data conversion, processing, interpretation and analysis of airborne and satellite imagery datasets. We have multi domain expertise of working with coarse to very high resolution airborne and satellite imagery and wide spectrum of imagery applications for geospatial data development and analysis. Our software expertise ranges from globally available commercial software like ERDAS, ENVI, PCI Geomatica with Airphoto Ortho Suite, Datem, Socet Set, Socet GXP, Global Mapper Lidar module to open source softwares like QGIS, GRASS, Fusion, LAS tools etc.

We have extensive experience in interpretation and processing of airborne and satellite imagery and have worked with most of the commercially available satellite data products.RMSI uses its in-house developed proprietary tools, 3D Workstation (Digital Photogrammetric Workstation), batch processing and distributed processing techniques to cater to the demands of its clients on time and to budget.

Solutions

Remote Sensing

GSI’s remote sensing imagery services range from satellite image procurement from national & international agencies / imagery providers to image processing, interpretation and image analysis for various applications.

Our remote sensing services are used for macro level applications such as land use planning, natural resource management, watershed management, wasteland mapping, corridor mapping for industrial zone, dam site identifications and livelihood development. Our services include:

  • Seamless raster data products
  • Terrain Mapping & Digital Elevation Modeling
  • Land use/ Land cover (LULC) Classification
  • Change Detection Mapping & Analysis
  • Advance Spatial Analysis

Photogrammetry

GSI provides photogrammetry services for more accurate needs such as 3D building high resolution databases that are created using the most recent high resolution stereo pair aerial photographs, satellite imagery, best available topographic maps, field inputs and information available from secondary sources. The data layers provided as part of such a database are Digital Surface Model (DSM), Building Height Model (BHM), Vegetation model, Digital Terrain model (DTM), Land Use data (Clutter data), Vectors, Orthoimage, and Text. We utilize our own proprietary photogrammetric tools as well as commercial photogrammetric software and processes. Our services include:

  • Aerial Triangulation – Orientation and Adjustment of Aerial/Satellite Stereo Pairs
  • Ortho Photo Generation
  • 3D City Models using Mono / Stereo Images
  • Digital Terrain Modeling and 3D Visualization
  • DEM and Contour generation from Stereo images
  • Photorealistic 3D Landmarks
  • Photorealistic 3D Building Data
  • 3D Geo databases – Stereo Data Extraction – Feature Mapping
