Aerial photography

The National Park Service has a data clearing house for New Mexico national park GIS information, including DOQs for various national park-containing areas of New Mexico (including White Sands National Monument). The DOQs are in MrSID format.

NAIP imagery with Mapserver, tilecache, and JOSM

MapServer

UNM MapServer is needed to reproject from EPSG:4326 to EPSG:900913 (Google Mercator) projection.

tilecache

tilecache takes converts TMS requests (made by Mercartor, JOSM, Potlatch) and turns them into WMS requests, serviced by the custom Mapserver instance we setup above.

JOSM

[22:33:24] <iandees_> so if you open up ~/.josm/preferences and add the following two lines: 

slippymap.custom_tile_source_1.name=NAIP
slippymap.custom_tile_source_1.url=http://hypercube.telascience.org/tiles/1.0.0/naip/

Another test server: http://cube.telascience.org/osm/oltest.html?zoom=13&lat=44.9704&lon=-93.28579&layers=B0000T, that'd be configured: 

slippymap.custom_tile_source_1.name=NAIP
slippymap.custom_tile_source_1.url=http://cube.telascience.org:8000/naip/
