I agree with you, Ujaval. Getting 5.6m data in the public domain will be a 
big boost. 

But I am curious to know from others what their experience has been with 
the quality of this 5.6m (IRS P6) data. For instance, I found the spectral 
quality to be rather poor: it boasts of being 10-bit but all the data are 
clustered in a 7-bit space. So we had to go back to coarser Landsat-8 
because it gave better spectral quality (not just more bands).

On the rest of the policy: I am wondering why they say nothing about 
drones, about UAV-based LIDAR, and so on, which are really the cutting-edge 
these days, are they not?
