 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.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[शरच्चंद्र लेले]

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 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).

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Ved Kolhatkar]

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.

The title says "Space based remote sensing", so including UAVs probably
need a policy of its own. UAV operators are already able to sell data and
services - provided they comply with DGCA, so not sure how this policy can
help further.

Good point. 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.

US's hi-res limit was 50cm till 2014 and was revised to be 25cm now (with a
caveat for Israel imagery at 40cm
).
Maxar now sells 30cm images commercially. If I understood the policy
correctly, the new threshold for India in this policy would be 50cm.

 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

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

I think Thejesh's idea of a joint response is excellent, and am happy to 
contribute.
My immediate observation is that 
a) the RS policy does not cover drones/UAVs, which according to me is the 
hot area, where a lot of application development is also required. The UAV 
related policy by DGCA is purely regulatory (what permissions are required 
etc), not developmental
b) the opening of 5.6m imagery is great. HOWEVER, there is lack of clarity 
of whether the govt will continue to support the IRS P6 (or equivalent) 
programmes well into the future. There is no clear commitment. There is 
talk about past images, and open sharing, but obviously if commercial 
players come in, their data will not be shared. So a bit more clarity on 
whether (like USA) the state agency will continue to do imaging till 5.6m 
resolution and leave the 5.6m to 1m field for commercial providers is 
required.
c) the shift from NRSC to a socalled PSU is noticeable and its implications 
unclear. What we do know as users is that NRSA is not particularly 
accountable to users in terms of quality of data, transparency in what they 
do (they will suddenly stop taking requests for imaging on particular 
dates, saying they are doing a full run for govt), technical transparency 
(quality), and promptness. And it is not clear in the policy how this 
accountability will be enforced vis-a-vis the PSU either.
d) The USA defines 'high-res' as 0.5m and below. That's why commercial 
providers stop at 0.6m. (please correct me if I am wrong--or if this is 
outdated). We should use the same threshold, not 1m. Because otherwise our 
data users are unnecessarily penalised, while 0.6m data on India are 
available to users located in the USA or elsewhere!
e) accountability of the high-res committee--they simply turn down requests 
without any reason. Who holds them accountable?
f) If commercial providers are to come in from India, how will they beat 
existing global suppliers of 1m data such as Ikonos and others who are well 
established?

 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.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

Rajya Sabha TV just now called saying the programme got cancelled. Typical 
of them.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

Btw, I will be appearing on Rajya Sabha TV tomorrow at 1pm with MoES Secy 
for a panel discussion on this new policy. So do send in more comments 
tonight/tomorrow morning, AND listen in on that discussion.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

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?

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Naveen Francis]

Hello Thej, 

Definitely, we should send comments to mention data to be in 'government 
open data license'
We should reach out to like-minded orgs ?

1. Space Federation of India https://www.spacefed.in/
2. Association of Geospatial Industries (AGI) - http://agiindia.com/
3. Indian National Cartographic Association - https://www.incaindia.org/
4. Open Source Geospatial Foundation – India - http://osgeo.in/

Thanks,
