These resources are described in some detail, including video tutorials, at thingstolucat.com.

A data-driven approach to remote overland travel allows you to identify best routes, bailouts, and best-guess at current conditions.

Remote Sensing

Other imagery

Weather

Route planning

Caltopo

  1. $20 annual subscription to access the superoverlay.kml (Free upgrade for SAR)
  2. Download the superoverlay.kml to view topo map, etc.
  3. Recently added MODIS and Sentinel imagery

Topo maps

  1. Caltopo offers a very mature printing interface. Unfortunately, I find that most of the maps in Alaska need some contrast adjustment to be workable.
  2. USGS quads can be downloaded and printed for free from topoView.
  3. DNR offers topo maps for view and print, without having to select individual quads.
