GIS Sector/Services:
1. Satellite imagery acquisition and processing, geometric and radiometric correction, ortho-
rectification, image enhancements,
2. GIS-CAD Conversion: From Auto-cad drawings to shapfiles or databases.
3. GIS data collection (digitizing, or using old data/gis/cad), arrangement (according to our
requirement, editing, topological error), and its application.
4. Maps: for surveying or verification or ground truthing.
5. Verification of GIS Data: by going on fields with filed maps (made above).
6. Photogrammetry: Using aerial images for detection of elevation, DEM, ortho-rectification.
7. Geo-databases: for thematic maps, like, slope, flood plain, soil types, landuse, geology, ground
water, elevation etc.
8. Data Analysis: for routes, starting and ending of routes, by network, spatial, geo-statistical
analysis, etc.
9. Web Development: Web GIS, Interactive interface, developer and user interaction, dynamic
maps (updation on intervals, 6 hours), satellite imagery base ground, flex, animation, etc.
10. Upgrade Overview: sms (short message service) alerts, tv screen/monitor overview, brouchers
(job stalls), organogram (interactive flow charts), etc.
11. Cartography: maps at different scales.
