5. OSGeo – Open Source Geospatial Foundation OSGeo Mission Statement To support the development of open source geospatial software, and promote its widespread use. OSGeo Goals To provide resources for foundation projects - eg. infrastructure, funding, legal. To promote freely available geodata - free software is useless without data. To promote the use of open source software in the geospatial industry (not just foundation software) - eg. PR, training, outreach. To encourage the implementation of open standards and standards-based interoperability in foundation projects. To ensure a high degree of quality in foundation projects in order to build and preserve the foundation "brand". To make foundation and related software more accessible to end users - eg. binary "stack" builds, cross package documentation. To provide support for the use of OSGeo software in education via curriculum development, outreach, and support. To encourage communication and cooperation between OSGeo communities on different language (eg. Java/C/Python) and operating system (eg. Win32, Unix, MacOS) platforms. To support use and contribution to foundation projects from the worldwide community through internationalization of software and community outreach. To operate an annual OSGeo Conference, possibly in cooperation with related efforts (eg. EOGEO). To award the Sol Katz award for service to the OSGeo community.

16. Now what…. How is this useful to you???????

17. Personal Use…. Thanks to Dylan Beaudette : http://casoilresource.lawr.ucdavis.edu/drupal/node/244 Navigating Wilderness Areas with GRASS Classification Cost Surface

18. Creating Data…. Digitizing, Modifying, extracting… Context Layer Viewing Create new shapes Create new attributes

19. Transforming Data…. How to get coordinates in UTM to Geo-NAD83?

20. Web enable standard geo-data….

21. Web enable non-standard geo- data…. How to display and interact with model data? GIS Model Results Web Based Real-Time GIS Model

22. Spatially enable your database…. How to select data within a polygon area?
