3. Data Management  Cataloging / Organization  Data Discovery  Metadata  Keywords  Updating  Cataloging / Organization  Data Discovery  Metadata  Keywords  Updating

4. Data Storing  Create, maintain and store spatial data  Shapefiles, excel tables, databases (such as PostGIS), WMS layers  Create, maintain and store spatial data  Shapefiles, excel tables, databases (such as PostGIS), WMS layers

5. Data Access  Different Users and different formats  Viewing, querying maps  Different Users and different formats  Viewing, querying maps

6. Demonstrating the Use and Concepts of a SDI  GeoNode  Free and Open Source!  Version 2.4  Configured on Ubuntu operating system  Works with GeoServer and PostGIS  Other SDIs, such as GeoNetwork

7. USE CASE EXAMPLE  Lots of data in different formats, vector and raster  Different scales including National, State, County  Different types of users, some proficient in GIS, others are not

8. Uploading Layers to Catalog  Different data formats, raster, shapefile, other vector  Control over user permissions  Different data formats, raster, shapefile, other vector  Control over user permissions

9. Styling Layers  Not quite as extensive as some other mapping programs (Desktop GIS).  Shapes, add labels, and adjust the look of the points based on attribute values and scale.

10. Managing Metadata  Keywords are custom “tags”  Categories are based on metadata Standards  Both provide ways of standardizing the way data is accessed and organized

11. Automated Publishing to GeoServer  You can now access and share WMS layers with Geoserver.

12. PostGIS Database  Layers are automatically added to PostGIS database  Ability to connect GeoServer to other data sources as well.

13. Viewing and Creating Maps in Mapviewer  In the Mapviewer, you can add multiple layers, (your own or selected)  Publish and save completed map  Access WMS

14. Downloading Layers in Different Formats JPEG PNG Zipped Shapefile GML 2.0 EXCEL CSV KML GeoJSON KML TILES

15. Uploading Documents  Includes PDFs, Spreadsheets, etc.  Documents can be linked to spatial data layers in GeoNode  Includes PDFs, Spreadsheets, etc.  Documents can be linked to spatial data layers in GeoNode

16. Some Things to Consider…  Benefits  Limitations  Accessibility  OPEN SOURCE  Benefits  Limitations  Accessibility  OPEN SOURCE
