Hello,
I just wanted to feedback from the community for our effort to map the
slums in Klong Toey, Bangkok. The size of the area is about 1km x 2 km
around here <https://www.openstreetmap.org/#map=16/13.7071/100.5763> and
I have captured a sequence on Mapillay here
<https://www.mapillary.com/map/search/13.711477616336708/100.5742382513609/17>.
There are several challenges here including access to internet and
English literacy, so I have come up with the following rough plan.
1. Put out a call for volunteers, work with NGOs in the area to find
local kids who are interested in putting their community on the map.
2. Train the kids in using ID editor. I think I will limit them to doing
specific things i.e. walkways, houses, trees, restaurant, convenience
stores with individual kids limited to 2-3 features to avoid confusion
then as they get the hang of it, increase their repertoire.
3. Take over a local internet cafe for a day for training and mapping
purpose.
Now I'm not sure about the rest of the process, you can see from
Mapillary that due to the somewhat dense nature of the community, GPS is
inaccurate and neither Bing nor Mapbox has enough of a resolution to be
meaningful. So I have several (possibly overlapping) ideas.
a) hire or borrow a drone to take aerial imagery and upload to
openaerialmap and use that as a basemap but I'm not sure how possible it
will be to see through the roofs.
b) get a team of surveyor students from Prof. Garavig to map out the
paths in the community (it's pretty big so I'm not sure how tine
consuming it is) then have the community kids fill in the blank.
c) use walking papers and have the kids go out, sketching what they see
from the rooftop but I feel this may be prone to errors.
Does anyone have any experience or tips they can share on how we can
achieve this?
Best regards
Mishari
