I work for a non-profit (meaning we have no money) and we are trying to find a free/open source GIS software. After doing some research online, I have narrowed my choices down to either qgis or ILWIS. We will be doing some basic analysis, including finding locations from a list of criteria, proximity analysis, and some topographical views. Which program do you prefer? If you do not like those choices, which would you recommend? Thank you in advance for your input.
