Dear Ved,
I agree that may be the reason. But I am wondering if it is a good
enough reason. In all new technologies, state agencies have the capacity
and the onus to take risks and carry out R&D that will speed up their
deployment, iron out kinks and concerns, ensure that the technologies
become accessible for the right uses and to the weaker sections of
society that may not be able to afford commercial ones, and to state
agencies working for the public good. Since drone-based RS is indeed a
cutting edge technology, I was hoping the policy would take cognizance
of that and propose positive steps to engage with it, to build it up,
and make it available. (The way govt did for satellite based RS).

I think the reason why Department of Space might not be commenting
much on drones or UAV for that matter is that,in India drones are
mainly used for strategic purposes in order to fortify India's
defences . Commercial use of drone requires registration in India
which could be a bit tedious process and even when one registers they
have to follow rules and regulations which if are violated comes with
a penalty. Even though India does not outright ban the commercial use
of drones . It still requires a person who is licenced to fly a drone.
Another reason might be that operating and using a drone is not a
cheap affair which means it cant be afforded by all. No doubt
UAV/drones are cutting edge technology. If at all there are more
relaxations to usage of drones/UAV in terms of rules and regulations,
its cost etc we will definitely see a rise in data being available to
public not just by data enthusiasts but also through official channels.

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?

Hi Sharad,
Thanks for sharing. From the perspective of sharing ISRO's own
data, the policy says
" In the interest of promoting research, innovation, societal
applications and value addition, DOS shall make IRS satellite
data having GSD of 5 meter and coarser, easily accessible on
‘free and open’ basis. "
I think this is really good. As the best open remote sensing
multispectral data currently is Sentinel-2 (10m), ISRO sharing
LISS4 (5.6m) data puts them ahead of USGS and ESA. Of course,
the concern would be the implementation and how fast they can
make that data available. My comment here would that they
adopt a true open data license for this data, like Government
Open Data License.
