Comments on: Taking remote imagery offline to Nigeria http://highearthorbit.com/taking-remote-imagery-offline-to-nigeria/ Transmitting ideas, observations, and images from 42,000 km.

I've pointed several people to it in Afghanistan. OpenAerialMap has decent coverage of Afghanistan from the Rampant Lion data. http://www.openaerialmap.org/datasource/9/ I'm working on finding better data from the Rampant Lion II project to put into OAM... To paraphrase Gibson... 'the data is here, it's just not evenly distributed (yet)'. Thanks for putting this into a blog post! I’ve pointed several people to it in Afghanistan.

It works fine for me (since I use OGC WMS servers alot I configured my mimetypes to recognize capabiltities documents and open them in an XML editor just like word docs and other odd formats I use a lot). As for Sean's comment about WMS scraping I'm pretty sure that JPL provide a tile service to save people trashing the server by doing this. See http://onearth.jpl.nasa.gov/tiled.html for more details.

Imagery is still going to be an issue, but again, a grant could help. WRT to your WMS scraping, Not that I'm condoning it, but I'll admit that logs at JPL in November probably would reveal that this tool, if you make a few changes to create geotiffs with some gdal intervention, works wondefully for grabbing very large areas via WMS in small tiles automatically: http://webak.upce.cz/~uozp/mapgrab/mapgrab.html Sean @Sean had trouble posting this – so putting it in for him:

I appreciate your points, especially that "even when there is data, it’s still very difficult to find and utilize." I know VE offers offline content through 3rd party resellers, like i-Cubed, but am afraid to ask about the costs. I hope the discussion continues as I am sure this is a common issue for folks working offline or in remote regions. Thanks for sharing, Ben Andrew,
