Those are the main ones. I have more on my list -- some we already have in house, some will be easy to get, and a few are more like wishlist items.

Here are the additional ones:

Nick and I estimate that, to create tiles to zoom level 17 for all of OR and WA will be approximately 31 million tiles. Way over the 50k limit for our version of Arc2Earth.

The other option, rather than pre-generating all 31 million tiles for each layer, we could set up a live map server using Mapnik, Mapserver or Geoserver. This would mean doing the cartography outside of ArcMap (in something like TileMill) but we could render the tiles on-the-fly only as needed. This can be pretty fast if you set up caching. This is probably the way to go for maps that have ridiculous numbers of tiles since no one is ever going to zoom in and view every single tile at zoom level 17. See http://wiki.openstreetmap.org/wiki/Tile_Disk_Usage for the stats on open street map… only a small fraction of the high zoom level tiles are ever viewed so it’s sort of a waste to pre-render them all.

The tile server is up and running. Need to populate it with some data and load those into the map interface.

would be neat to have forestplanner report out a list of user's bounding boxes so we could precache all the tiles for their particular geography down to a very detailed geography.
