Since purchasing our AS last spring we have been searching for some kind of a mapping tool, atlas, or other means to aid in identifying public land boundaries. Here in the west, there are often privately owned parcels interspersed within public lands with no obvious boundaries. As an example, there are two major rivers in N Idaho that offer wonderful boon docking opportunities but as one drives along there are seldom signs or other guides that will add in determining land ownership.
We purchased some maps and atlases only to find that the scale was such as to render them of very little use in locating potential boon docking sites. Up until now, we have followed the advice given on this forum and sought information from locals which has led us to some great locations and some that were not so great.
A friend just introduced us to a mapping application that appears to be what we have been seeking. It is available to run on iOS, Android, or on a PC via the web. The application can display up to 5 different maps overlaid upon each other and the user can select these from an assortment of topo maps, street maps, satellite imagery, and overlays that depict private and public lands. The GPS in your phone/tablet will, of course, show your present position. If you are going into an area of questionable cell reception, you can download areas of interest to your device. The application also provides the ability to print out paper maps for those who prefer that medium.
The application is called Gaia GPS and more information can be found at gaiagps.com. The application for your device is free and access to the maps is available on two levels. Basic access is $19.99 USD / year and Premium Access (which provides additional maps and overlays including the parcel ownership ones) is $39.99 USD / year.
Here is a link to a limited time promo which will give you full, unrestricted access to the premium content for 90 days:

I have no connection to or relationship with the developer other than as a user of his product. If you elect to try this mapping application and have any questions about it’s usage you can contact the developer directly at
copeland@gaiagps.com. I have found him to be very quick to respond and very helpful. Or, please feel free to PM me and I'll help as best I can.
Here are a couple of screenshots of some BLM land along some rivers that we are going to go check out for boon docking potential.
