An insightful discussion has been going on recently on the OSGeo-Discuss mailing list, around the question Can I do the same GIS tasks with OS (as with ESRI)? Among the main points: if you think open source, think modular. And: Good cartographic output remains a problem for open source. Other interesting issues are discussed, for example db capabilities.
Bilko is a complete system for learning and teaching remote sensing image analysis skills (from UNESCO).
MultiSpec is a a freeware Multispectral Image Data Analysis System for image data, and intends to transfer this technology to the user community in as rapid a manner as possible (from PurdueÂ University and collaborators).
