> 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

FWIW, if you and your volunteers take tons of pictures for Mapillary
and the Internet connection isn't good enough to upload them, you can
physically mail them a hard disk. Or have them mail you a hard disk
and you fill it with photos and ship it back. They have done it before
for special situations like this.

Let me know if you're interested in that.
