ISRO's Web GIS Services for
Earth Observation Data-
MOSDAC & VEDA
Shashikant A Sharma Space Applications Centre (ISRO)
Aircraft positions picked up by ESA’s Proba-V satellite
Using an experimental Automatic Dependent Surveillance – Broadcast
(ADS-B) receiver. These signals are regularly broadcast from aircraft,
giving flight information such as speed, position and altitude
Defense Conversion spin-offs
• Location via GPS – millimeter accuracy – available in cellphone – super high capacity mass storage – pettabyte and more systems
• High spatial (<1m) & temporal (every hour) resolution satellite remote sensing – High resolution: 30 cms now, 10cms soon? – Near Real time imaging
• Communication revolution – super high capacity networks, even to the home – wireless (cellular) communication with anything that
moves anywhere on earth
Technological Trends Underlying the Transition
Information Technology Evolution
• Interoperability: – Easier sharing of data between users, and among vendor
products
– Metadata ; OpenGIS, Spatial Data Transfer Standards
– Mash-ups
• Commercially enhanced data – public data made dramatically more usable/useful
• Spatial data tools in DBMS and Software Dev. Env. (e.g. OOPS )
– Oracle Spatial, PostGIS (spatial database engine)
– GRASS, GDAL .. Open source Libraries
• 3-tier computing : – user interface (client workstation)
– analysis (applications server)
– data (multiple distributed data servers)
Technological Trends Underlying the Transition
Need of Web GIS
Increasing demand for availability of geographic information to the public. The fast GPS, Remote Sensing and Satellite images provide GIS with huge databases which causes serious data management problems for maintaining, updating and exchanging geographic information;
Establishing open and distributed information services will improve the efficiency of GIS databases management and reduce its maintenance cost.
Web GIS is a Geographic Information System distributed across networked computer environment to integrate, disseminate and communicate geographic information visually on the World Wide Web over the Internet.
