Now that USB flash memory drives are so large and so cheap, we can start running programs off of them. We’ve seen that you can run Firefox and Thunderbird (among many others) on these drives, but many don’t know you can also run desktop GIS software on it. Head over to QGIS, download the latest version and install it. Then navigate to the QGIS folder (on windows this would be c:/Program Files/Quantum GIS) and copy it to your flash drive (You’ll need about 80 MB free). Anytime you need GIS, you’ll only have to whip out your memory stick and plug it in. Then just browse for the “qgis.exe” and you’ll be set.
