GeoServer is an open source software solution for managing geospatial data. It allows for the sharing of geospatial data through interoperable web services like WMS, WFS, and WCS that comply with OGC standards. It has a user-friendly interface and supports security, administration, and extensions. GeoSolutions is an Italian company that founded GeoServer and contributes to its development.

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)
