Ten Things You Need to Know about Open Source Geospatial Software

All Points Blog offers an entry named Ten Things You Need to Know about Open Source Geospatial Software.

Here's the list, and head to the entry to read further explanations:

  1. Open source geospatial software refers to GIS, GPS, spatial data management and related developer tools and end user applications delivered with an open source license.
  2. An open source license must meet the definition developed by the Open Source Initiative.
  3. Open source software is written by a community rather than a development team associated with a single software company. [...] Some do this as part of their “day jobs,” while others volunteer.
  4. The Opposite of Open Source is Closed Source or Proprietary Software, not Commercial Software
  5. Open Source Software is “Just” Software
  6. OSGeo is the Body for Open Source Geospatial Software
  7. Open Source and Open Standards-based Software are not the Same Thing
  8. Implementing Open Source Software May Cost Money
  9. Software developers and software users mix and match open source and proprietary software all the time. Esri’s ArcGIS, for example, includes the open source GDAL (raster handling) library. 
  10. Open source licenses are designed for software, not data. There are other licenses appropriate for data.
