Gmap4 = View topos/aerials *offline* and your geolocation

I have posted here before about Gmap4 which is an enhanced Google map viewer that I developed. Up until this summer I believed that Gmap4 would not work if your mobile browser was offline. I was wrong. If you follow a few simple instructions, many (but not all) of the Gmap4 features will work just f...

Thanks for the kind words. I took a look at supporting NAD27 and discovered that datum is a mess. See for example: http://gis.ou.edu/sympa/arc/okgis/2008-07/msg00018.html Sorry, but the pain would not be worth any gain.

Foundry Canyon is the third major canyon south of Mormon Point; I'll be including a TOPO map of its location in my TR. It's definitely worth hiking up to the first impasse, because the narrows are so incredible! You can get a little over a half-mile in the canyon, and the last quarter mile or so is...
