Thanks for the discussion.
I've gone back and forth with my research on GPS devices between the Garmin Vista HCx and the new DeLorme Earthmate PN-40 device.
Here's a nice review of the latter:
http://gpstracklog.com/2009/02/delorme-earthmate-pn-40-review.htmlBackground: I'm a total handheld GPS newb which concerns me with the thought of using the DeLorme’s Topo USA 7.0. However, I will be able to spend $29.95 and get access to:
•1:24,000 scale USGS topo maps
•B/W aerial imagery
•Color aerial imagery
•SAT 10 imagery
Since I will be riding is Eastern hardwood, I don't know if the aerial or SAT imagery will be helpful, but I do know the USGS quad information will be very valuable. Garmin has yet to be able to do this outside of a few national parks. I did find a page that has the ability to convert USGS quads to Garmin maps:
http://moagu.com/However, I wouldn't know if this solution is more or less complex than going with the DeLorme unit since I don't have either unit in hand to be able to figure it out.
Battery life appears to be shorter with the DeLorme unit which may be a deal killer.
Lastly, it looks like I will be able to use topofusion to modify an existing gpx file for my route. I will have to cut out certain sections and add additional road mileeage in. Is this correct, or do I need another program?
Thanks!
