access the data
under this rule

22. Improved Raster Reprojection
 Raster reprojection  complex
process
 Idea:
 try to approximate the overall
transformation with a simpler
one, either a single affine
transformation or a piecewise
composition of them (grid warp)
 Ability to specify threshold for error
acceptance
 Iterative approach (local optimization)
 Trade off between speed and
precision

23. SQL Parametric Views
 SQL View as a GeoServer Layer
 No need to actually creating a view in the database
 View can be parametric
 WMS and WFS allow parameter substitution
 ….&request=GetMap&viewparams=low:2000000;high:5000000
 Default values for parameters
 Validation with regular expressions
GFOSS DAY 2011, Foggia

24. Improved Clustering
 New parameters to allow multiple GeoServers to work
against the same network shared data directory
 Per server log file location
 Disabling GWC meta store
 Disabling GWC disk quota management
 GeoWebCache Enhancements
 disable the embedded GWC completely,
 hide the embedded GWC to the public
 keep the embedded GWC only for fast layer seeding
 only one GWC at a time is allowed to write on disk
GFOSS DAY 2011, Foggia

25. Virtual Services
 Expose multiple OGC service endpoints per installation
 One virtual service per workspace
 Expose only layers defined in such workspace
 Use cases:
 Provide clients with focused/theme centered data sets
 Provide each department of a single organization with its own set
of services
 Limitations:
 Single administrator for the whole server
 Service metadata (point of contacts and the like) still configured
centrally

statistics, raster/vector format conversions and more)
 Integrated WPS
 Automatic publishing of results
 Embedding processes into SLD styles
 Reuse processes as rendering transformations
GFOSS DAY 2011, Foggia
25 Novembre, 2011

28. WPS*
 Deficiencies
 No support for asynchronous requests
 Missing request limits enforcements (e.g. input/output
maximum dimensions)
 Wish list:
 Scripting (Jython, GeoScript)
 Sextante, IDL, JGrass (Grass?) integration
 Improved robustness
 Jiffle (jai-tools) based raster algebra
 Create new layers as dynamic WPS processes
(computing data on the fly as requested)
GFOSS DAY 2011, Foggia
25 Novembre, 2011

29. Image Server*
 Turning GeoServer into an Image Server
 Serving pure Imagery
 No geo-reference need/available/(would make sense!)
 Special Coordinate Reference Systems defined
 Interoperability with WMS clients
 Respecting EPSG conventions
 EPSG:404000
 See here
 Improved support for data with
bad/missing geo-reference!

30. Aggregating data store
 N layers, remote or local, sharing the same structure
 Aggregating store puts them together dynamically, the
client wil think there is just one layer
 Parallel data fetching
 Can be configured to tolerates
temporarily unreachable data
