GIS Librarian Blogger provides links of free, powerful utilities
GIS can be a sprawiling subject, and systems can run very expensive–usually at the government/enterprise level. But a lot of map addicts would like to play with, experiment with, and get GIS experience.
It can be done for free, as geospatial blogger mapz shows us:
These are the freely available applications and services that make up my own personal free GIS. Individually, many freely available applications do not of themselves constitute a full geographic information system, but when these are all pulled together within one suite of tools…Well, it is remarkable what someone can do without spending a cent. (And without needing to spend an enormous amount of time developing your own applications out of open source components or needing to learn, or install, complex applications, such as GRASS GIS.)
Mapz gives us pointers to tools in Geocoding, GIS Processing, and an armful of other subjects; they run from the pedestrianally-familiar Google Earth to the less-than-known-to-the-layman, such as STARS, GeoDa, and QGIS. There are even pointers to Linux tools. And you’ll find this treasure heap here.
Mapz’s typically excellent blog is a regular read, we say check it out in full.
