Back to GIS: Exploring Mt Lassen via uDIG, episode 1
Monday, August 31st, 2009I’ve old mapping projects still sitting around but the possibilities that could be met on a road trip to Lassen Volcanic National Park struck me as “urgent.”
I’m going to try uDIG instead of QGIS, because i’m lazy. The QGIS Mac OSX version requires separate installation of dependency frameworks. It seems to have been streamlined, but i’ll start with the easier system.
On my Mac, uDIG Version: 1.2-M6 took a little time starting up. An alert box notified me that files had been written to my home directory and prompted me to restart. There was also an error about a file name with a bad character. The “About uDIG” panel has a link to “Installation details” and that has a link to the log: i was able to review the error more clearly there. I note that this is not a “clean” install, but on top of a 2007 install. Files seemed to go in
./Documents/uDigWorkspace/ ./Library/Preferences/net.refractions.udig.plist
I followed through most of the first walkthrough, deleting the “map decorations” from the catalog, by accident. (I wanted to delete them from the map, and should have done so in the layers window.)
Meanwhile, i downloaded USGS data on Lassen and unzipped it to find … no shapefiles, just .ADF. I appear to have run across .ADF before, when struggling with .E00 data. Meanwhile, the Sierra Nevada Ecosystem Project is in the .E00 format.
Suddenly, the fact it’s 9 pm and i’ve not had dinner takes on significance.
