6. GeoServer User Interface

7. Integrated Security
 Spring Security
 RBAC on layers and services
 Built-in version with simplified rules
namespace.layer.mode=role1,role2,...
A name, or * to r: read The roles that will
mean “any” w: write be authorized to
access the data
under this rule

8. GUI: security configuration

9. Security Developments in 2.1
 Security Management at the feature level
(record in DBMS)  read and write filtering
 Hide sensible attributes
 Discriminate visible areas on a per-user
basis
 Rules for services and layers
 Server side framework available, open
source implementation needed!

10. RESTConfig
 Programmatic configuration of layers via
REST calls
 Workspaces
 DataStores/CoverageStores
 Layers and Styles
 Exposing internal configuration to remote
clients
 Ajax-JavaScript friendly
 “Core” Module since 2.1
 Integrated Security

12. WFS
 Dissemination and filtering of vector data
 WFS 1.0 and 1.1 support with transactions
 Formats:
 GML 2, 3.1 e 3.2
 GeoRSS, GeoJSON
 Shapefile (zipped)
 OGR (configurable)
 Extensions
 CQL
 WFS 1.0 with on-the-fly reprojection

13. Complex Feature*
 Application/community schemas
 Complex Features
 Attributes as sub-features
 Attributes as list of features
 Tree-like structure
 Heterogeneous data sources
 INSPIRE!

14. WCS*
 Raster data dissemination
 Raw raster data useful for analysis, no maps!
 Support for TIME and ELEVATION (via ImageMosaic plugin)
 WCS 1.0 e 1.1
 Output formats
 GeoTiff, ArcGrid
 GDAL based formats*
 Extensions
 ELEVATION as band management*

15. WMS 1.3.0 e SE 1.1
 WMS 1.3 support (INSPIRE)
 Basic support for SLD 1.1 and SE 1.1
 Full support for SLD 1.0
 Many rendering extensions available!

20. Rendering transformations
 On-the-fly data transformations
 Calling WPS processes from SLD docs
 Optimized for performance

21. Rendering transformations
 Point feature extraction from two band
raster data (e.g. Wind(u,v))
 Computation of direction and module from
SLD

22. KML/KMZ
TEMPORAL SERIES
KML EXTRUDE KML SUPEROVERLAY

23. ImageIO-Ext Support
 JAI ImageIO Extension
 Plugins:
 BigTiff*, netCDF-CF,GriB1,MatFile 5, HDF4
 JP2000 (Kakadu)
 GDAL 1.7.3
 GDAL integration via ImageIO-ext
 JPEG2000,MrSID, ECW
 BigTIFF, ERDAS Image, HDF4

24. GeoWebCache Integration
 Direct calls to GeoServer
GeoServer rendering engine
 Support for layers modified
through WFT-T
GeoWebCache  Support for various tile
protocols
 GMap, Gearth
 OpenLayers, VEarth,
Bing
 Speed-up factor 10/100
 Disk quota support
Persistent raster/KML
tile cache

25. WMS* Cascading
 GetMap and
GetFeatureInfo
Cascading
 Suppport for
reprojection on-the-
fly
 GUI based mass
import of remote
layers

26. WPS*
 WPS 1.0
 Official Extension
 Raster and Vector data support
 High performance processes development (raster/vector
statistics, raster/vector format conversions and more)
 Integrated WPS
 Automatic publishing of results in WPS
 Embedding WPS processes into SLD styles

27. WPS: demo builder

28. WPS*
 Deficiencies
 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

29. Cross-Layer filtering
 “querylayer” community module
 “Find all sites within 100 meters from roads”
 Single CQL filter with WMS:
DWITHIN(
the_geom,
collectGeometries(
queryCollection('roads',
'the_geom',
'INCLUDE')
),
200, meters)
