[juneau-lug] More GPS

Another program that can download and upload data to your GPS is Quantum 
GIS (qgis). It brings in your waypoints and tracks onto a layer, and at 
the same time saves the data to an xml file. Qgis uses GPSBabel for the 
import and export. GPSBabel can convert your data into a bunch of other 
formats. QGIS can bring in georeferenced maps and photos onto seperate 
layers. Each layer has it's own properties, including transparency. I 
still have a problem getting things to line up properly, though. I'll 
have plenty of time to work with it once I'm on vacation.

Almost forgot. QGIS can bring in shape files (shp). The only shape files 
that I have imported were the ones that held the 24k grid of the quads 
in the lower 48 and Hawaii. This was useful for locating some additional 
DRG's (quads) that I was interested in, as well as the corresponding 
Digital Orthophotos.

BTW, I joined the Geocommunity ( http://www.geocomm.com/ ) to get all my 
GIS maps, etc. Some things are free to download, but for a small price 
($25), you can get 150mb of downloads. The free downloads can be kind of 
slow, so if you are in a hurry, you can burn up some of you download 
quota to get a faster download. Other items can only be downloaded if 
you have an account. The $25 is cheap compared to buying an image off of 
M$ Terraserver. Before I found the Geocommunity, I bought a single 1m 
resolution image from them for $50. It was a few years newer than the 
images I downloaded from Geocommunity, but the quality was poorer. I 
probably should try and get my money back.
