Got a couple of PH related shapefiles at home. Could be a nice after work hobby project. Except ironically it will only run on windows. Although MapWindow GIS is opensource. Hmmmn... Seems to be requiring dotnet 2.0 sdk too.
What I don't have is a windows installation. Bummer. Got to find the installer that came with the lappy. Its burried neath' those Ubuntu/FreeBSD CD's last time I checked. heh.
