GeoServer 2.2
Andrea Aime GeoSolutions
Justin Deoliveira Opengeo

2. Web Map Service (WMS)

3. Time and Elevation

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

&format_options=gif_frames_delay:200;gif_loop_continuosly:true
&format=image/gif;subtype=animated
But... why limit animations to
just to time and elevation?

18. Web Processing Service (WPS)

19. Asynchronous calls

20. Security

21. Authentication

22. Authentication
LDAP

23. User Groups

24. Passwords

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

30. Database level security

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
