[HOT] Optimal NAS tech specifications to serve imagery tiles

Wed Mar 22 16:34:03 UTC 2017

POSM was developed exactly for this type of use case. The status.md isn't
up to date and should be ignored.

POSM does host imagery with the new OpenDroneMap module. You can add a tiff
and it will be served as a TMS. You an also add any MBTile archive (bing)
and have that served as well. POSM is designed to take an AOI, use
collected imagery, host field papers, and have support for mobile data
surveys all offline.

Happy to answer any questions that anyone might have.
