I too am very interested, especially for using this on trail maps that do not exist in Google Maps. Please let us know when there is a demo version!
The problem with accepting the license agreement on Internet Explorer is fixed. Thanks again Mark5047 for reporting it!
Sweeeeet! PayPal transaction painless and secure. Followed simple instructions as prompted, excellent menu instructions. Trial run was on a non-public unclassified US Govt. 1:50:000 scale map measured in meters. Used the Droid camera to take picture of this very detailed topo map, went to Viamici app chose pic of map zoomed in to an area about 13,000 meters in horziontal wide, pinned my location and moved off 750 meters west pinned again. Tracked my position to my map via the indicator visual references proved I was right on the mark! Wanted to get feedback out soon on this as others have expressed interest, will continue to evaluate. Right now I find this app to be worthy of cost. Application of this product via non-public, not published, or Map signage is not only valuable but simple! I work law enforcement and many of my investigations require use of maps and scene diagrams. This app may prove to be one of my most useful tools! PS Developer is easy to work with and very helpful.
Okay, had a chance to work with the app some more and it is an outstanding navigation/reference device. Emphasis on reference since you can download map pics/stored or imported map jpegs to the app. If you use charts/maps (to scale) with Lat and Long or Map Datum grid coordinates you can increase the accuracy of your location. If your downloaded maps have POIs marked you can locate them from your position indicator easily as you navigate or if you just want to know your location on the map. Google maps etc. don't include everything a specialty map may have that the locals know or other tele atlas nav devices may not be up to date on, especially maps that have realty tax map key data, grazing land maps with paddocks and gates that the landowner has plotted and of course like others have mentioned national parks. What I would like to see as the app develops are waypoints and the ability to draw routes. The app currently does what it says and does it flawlessly.
First, I would like to thank Pueo for the detailed review. A happy client is what best motivates me to work.
The USGS - U.S. Geological Survey, Ordnance Survey - maps and geographical data of Great Britain) is accurate. So when you see a name of such an agency or information about a scale, you may be sure that this is an accurate map. However, I also found many maps without such information which are accurate.
Answering your question how the app handles such a situation: having two georeference points it is impossible to handle maps which are totally inaccurate. I am working on a version of Viamici which will allow that.
