These are not GIS or mapping software, but if you are looking for cheap, intuitive, effective and well-designed software for processing your summer vacation snaps or spreadsheets, consider these software programs:
- Acorn: an innovative image editor built with simplicity in mind. Fast, easy, and fluid, Acorn provides the tools you need to alter and enhance your images, without any overhead. Acorn feels right, it won't drain your bank account, and you don't need a Ph.D. in computer graphics to use it. Cropping, color management, transformations are a breeze.
- OmniGraphSketcher: helps you make elegant and precise graphs in seconds by combining the data plotting power of charting applications with the ease of a basic drawing program. You can import directly from excel. (Other Omni software includes OmniGraffle, my other favorite line drawing program (with TONS of stencils to steal ideas from)). On Tim's suggestion, I just recreated a series of excel charts for a publication using this software, and really like the switch.
