It would be nice to have up to date USGS maps.

One item that is often overlooked in TNP is the photo labeling. Like the street overlay, TNP includes the latest available - so the aerial photos are always labeled with current features and streets. In most cases, this produces a map that is more current and of higher resolution than the "US Map" series available from the USGS.

It is nice that the street maps & aerial photos are fairly up-to date. But, for our search & rescue group, it has been frustrating to work with maps where names of trails, lakes, mountains and other terrain features are out of date. It has been a source of confusion several times. Now we've bumped into it enough that we tend to look at other sources for terrain names, info, etc. first, and then see which names are still correct in TNPro.

Newer "traditional" hand-drawn USGS maps are not available because the USGS discontinued making them in the late 1990s. A few were updated by the USFS, but the vast majority date from 1980-1990.

Thus, like the USGS, we are now using current NAIP aerial photos with current street layers to produce maps. Those with our annual subscription receive photos and streets updates regularly.

We may consider adding the "US Map" topographic maps produced by the USGS as an alternate edition in Terrain Navigator Pro. These will have the same updates we provide (streets and photos) but with a few other features. However, they are significantly less detailed than the traditional hand drawn "quads."
