This is one of the three books identified by the Education and Curriculum Committee that should be written. The other books are Using open source GIS and Developing web mapping solutions using open source.

Approach for writing this book

We will start writing this book by listing practical development problems and then identifying how free geospatial tools can be used to solve those problems.

We need to list the tools and link to pages, which describe their general capabilities. http://freegis.org has a good list, which contains short descriptions and it has a quite good classification scheme with the only problem that it seems not possible make complex queries. Probably it would be a good idea to share the ontology as much as possible.

We'd like to develop this page somehow coordinated with the Programming Languages Project

  • Problem: Share GPS data between applications
    • Subproblem: Parse GPX
    • Explanation: GPX is an XML application for GPS data. Parsing gives us the GPS data.
  • Problem:
    • Subproblem: GeoTag Media
