We need state commitment to continue providing medium-res data. Another concern would be making this data available. If the data is not made available soon after acquisition - it is not really valuable. There is no commitment to making the existing data available in a timely manner to the public. > c) the shift from NRSC to a socalled PSU is noticeable and its > implications unclear.

Maxar now sells 30cm images commercially. If I understood the policy correctly, the new threshold for India in this policy would be 50cm. e) accountability of the high-res committee--they simply turn down requests > without any reason.

There's growing market for hi-res SAR data. I think there are opportunities for companies to compete by offering localized solutions and services along with data.
