Dear Ahasan,
Thanks for your replay,
Let see how far we can go in Haiti,
We take our time to be sure to involve the local population and OSM
contributors .
And is not so easy : )
For UAVs we train pilots because the material remains expensive .
And there is also a safety issue , so we have permits to fly in France and
Haiti .
And it is rather good news that there was a framework for UAV flight
authorization
in Bangladesh.
For NDVI we will let you know, but our methodology for the moment is done on a
small watershed.
Not like the one we have seen in Bangladesh, so we will need to adapt the tool
and methodology according
to the field reality.
All the best, FredM
If you have some contact

Dear Frederic,
Think you already have got my reply of your earlier mail ccd with
viven and steven.
As I told in earlier mail that since 2014 jan there is restriction on
flying drone without permission. One of my Japanese researches group
(cc) have done almost same study as you in Jamalpur district in 2013.
It was an ADB funded Govt (Bangladesh Water Development Board)
project. I think you could get the permission through BWDB or DDM.
I have read your methodology used in Haiti and like the PGIS approach,
it can give an accurate data set. Wondered to see that you are using
NIR camera and NDVI data also what was not used in Haiti. Waiting to
see its use. It will be an interesting study for me. Some tools are
not familiar to me like Orfeo-toolbox and Pix4D.
See you in April.
Best regards
Ahasan

Dear Syed,
I hope everything is going well.
I will try in the following weeks to move on this authorization to
fly in Bangladesh, any help are welcome.
We are working on a new methodology to use drone on risk reduction
project ( with OpenStreetMap Haiti, I am also an OSM contributor).
We will test a Near Infra Red NIR camera for land cover /land use
work.
We will see how far we can go.
We will use this camera S110 NIR
https://www.sensefly.com/drones/accessories.html
https://support.pix4d.com/hc/en-us/articles/202561429-Example-Datasets-Available-for-Download-Agriculture
https://www.sensefly.com/examples-of-postflight-processing.html
https://www.sensefly.com/applications/agriculture.html
So let see if it can be useful during a pilot test end April/May
in Bangladesh.
Even if we will do with an NGO, I am still using a Drone for OSM
activities, as a OSM contributor to improve our worklfow and try
to find useful use of it.
So don't hesitate to contact me, especially to see with the
authorization.
PS:
All our imagery are on OSM France server (Jean Guilhem are doing
the maintenance) . Available as WMS / TMS link
2014 images
tms:http://wms.openstreetmap.fr/tms/1.0.0/haiti_2014/{zoom}/{x}/{y}
2013 images
tms:http://wms.openstreetmap.fr/tms/1.0.0/iomhaiti/{zoom}/{x}/{y}
Or directly in JOSM if you check supplier = HT / Imagerie Drone
2014 (Haïti) or HT / Imagerie drone (Haïti)
https://josm.openstreetmap.de/wiki/Help/Preferences/Imagery
Software:
We will use Pix4D for the mosaic
And for the extraction of the land cover and other ( NDVI ) we
will use Orfeo toolbox http://www.orfeo-toolbox.org/otb/
All the best FredM

Hi Fred,
Thanks for your email. I think deploying drones will be a great
idea for mapping those places for better hydrological modeling. I
believe the marked areas are mostly rural in nature, and I don't
expect tall buildings there. However, we sure can check that
accurately. I also believe that the permission from the flight
regulation authority is possible. I know couple of people, who
can help us on that regard. Previously, we have seen drones being
deployed in different agricultural projects in rural Bangladesh,
and I dont think it will be difficult for us to get the permission.
I am copying this email with couple of my friends, who can give
you more information. Please let us know if you have any other
question. Also, please feel free to keep me in the loop.
Regards,
Ishtiaque

Dear all,
Terre des Hommes has conducted a DRR (disaster risk
reduction) mission in Haiti with OSM Haiti (they have seen
the Drone + mapping party

and https://www.youtube.com/watch?v=Oou32o-jR0M
<https://www.youtube.com/watch?v=Oou32o-jR0M%C2%A0%20> )
And now Tdh Bangladesh would like to deploy**the OSM Haiti
methodology and Drone in Bangladesh**for their mitigation
project in this area of interest
http://umap.openstreetmap.fr/en/map/tdh-bangladesh-drr_24362#10/25.6811/89.8242
What do you think? The idea is to have the best open
database to improve hydrological modelling (we discussed
the methodology in this events
http://eguworkshop.deltares.nl/index.php/agenda/index
Including local knowledge about the risk, a good elevation
model (height of the building, an up to date land cover,
road, etc....).
For sure we will need to obtain permission from the flight
regulation authority,
http://bdnews24.com/bangladesh/2014/01/30/caab-baf-permission-needed-to-fly-drones,
Any idea, possible not possible in your country.
All the best FredM OSM contributor
