Open to global scientific community for carrying out research proposals towards the utilizations of THEOS data in the following broad categories:
•Advanced applications for agriculture, land use/land cover, forestry, hydrology, coastal study, natural resources and disaster management including climate change & global warming
•Specific techniques development for innovative methodologies, techniques, metric and operational use of the data on a regional/global basis THEOS Announcement of Opportunity (cont.)
• THEOS data will be made available to the Principal Investigators (PIs) after the commissioning phase (around March 2009)
• The data sets required for executing the AO projects would be provided to the selected PIs at no cost after evaluation
