What's new in GeoServer 2.2
0 likes2,257 views
GeoServer 2.2 includes new capabilities for time and elevation support for both vectors and rasters. It also introduces rendering transformations, paging and stored queries for WFS 2.0, asynchronous WPS calls, and improved security features like LDAP authentication. Additional updates involve referencing support, an image collection store, virtual services, and expanded scripting abilities.

- 4. Time/elevation for vectors ● Single time (instant) support ● Interval validity support by selecting two attributes ● "Current" time always up to date ● Currently investigating integration with measured geometries and dimension based slicing
- 5. Time/elevation for rasters ● Image mosaic with time/elevation attributes in the tile index ● Tile index in shapefile or database ● Automatic extraction of time/elevation from file names via regular expressions

- 25. Referencing
- 26. NTv2 and NADCon support ● Support for high accuracy datum changes based on datum shift grids ● Error down from 4m (if you're lucky) to few centimeters ○ NTV2: canadian grid shift standard, used in Europe and Australia too ○ NADCon: american grid shift standard ● Support for official EPSG grid files ● Ability to add your own custom ones (work in progress)
- 27. Reprojection console ● Reproject single point or geometries ● Check what exact transformation is being used
- 28. Un-referenced data ● Serve unreferenced data: ○ CAD data (floor plans and the like) ○ large photos ● Made up new code to handle such data: EPSG:404000
- 29. Data access
- 31. WFS sorting and paging ● Available in all WFS versions (in 1.0 and 1.1 as a vendor param, startIndex/maxFeatures) ● Native, most efficient in spatial databases ● Emulated in all other data sources (suitable for smaller data sets)
- 32. New experimental OGR store ● OGR: rich set of readable formats ● Does not need special bridge libraries (uses BridJ to connect to native lib) ● Slower performance than native Java formats, suitable for smaller data sets
- 33. Image collection store ● Publish collection of non georeferenced images via WMS (eventually time varying) ● List and search provided off band as a separate tool ● One layer, select image with CQL_FILTER
