 Workspaces: organizational structure/folder/
virtual services
 Stores: connections to data sources
 Layers: the data and its configuration
 Styles: how to draw it
 LayerGroups: ready to use maps
 Processes
 Services: per service config details
 Security
Key Concepts
14th-17th July 2014

Virtual Services
 Expose different OGC services per workspace
 Styles and layer groups per workspace
 Have different
administrators per
workspace
 multi-tenancy
14th-17th July 2014

Administration GUI
14th-17th July 2014

RESTful Configuration
 Programmatic configuration of layers via REST
calls
 Workspaces, Data stores / coverage stores
 Layers and Styles, Service configurations
 Freemarker templates
 Exposing internal configuration to remote clients
 Ajax - JavaScript friendly
 Various client libraries available in different
languages (Java, Python, Ruby, …).
 Example, geoserver-manager:
https://github.com/geosolutions-it/geoserver-manager
14th-17th July 2014

RESTful Configuration example
 Automate management of layers and their
configuration
Get and
process data
Publish
new layers
via REST config
14th-17th July 2014

WMS
 Dissemination of Maps
 Fusing raster and vector data seamlessly
 Rule/scale driven rendering
 WMS 1.1.1 and 1.3 support

14th-17th July 2014

WMS: Rendering Transformations
 On-the-fly data transformations
 Calling spatial analysis processes from SLD docs
 Optimized for performance
 Examples: on the fly contour lines, heat maps,
point clustering, point interpolation, GCP based
image rectification
14th-17th July 2014

GeoWebCache Integration
GeoServer
GeoWebCache
Persistent raster/KML
tile cache
 Direct calls to GeoServer
rendering engine
 Support for layers modified
through WFS-T
 Support for various tile
protocols

WFS
 Dissemination and filtering of vector data
 WFS 1.0, 1.1 and 2.0 (since 2.2.0)
 Transaction and paging available in all versions
 Simplified filtering via CQL
 Formats:
 GML 2, 3.1 and 3.2
 CSV, Excel spreadsheet, GeoRSS, GeoJSON
 Shapefile (zipped)
 Any other format supported by ogr2ogr (configurable)
14th-17th July 2014

Rich Filtering Support
 Full standard filter support
 Scalar (<, <=, >, >=, =, !=, like)
 Temporal
 Spatial (intersections, touch, dwithin, dbeyond, …)
 Filters directly translated into native data source filtering
(e.g., SQL for spatial databases, OGC Filter for WFS
cascading, SDE filters, ….)
 Rich set of filter functions for advanced filtering (do math
and string manipuation in your filters):
http://docs.geoserver.org/stable/en/user/filter/function_refe
rence.html
14th-17th July 2014

More data access options
 Paging (native in WFS 2.0, back-ported to other
versions as a vendor extension)
 Joins (scalar, temporal, spatial) between feature
types (WFS 2.0)
 Stored queries (WFS 2.0)
 Reprojection
 Various built-in output formats (GML2/3.1/3.2,

 Official Extension
 Raster and Vector data support
 Many built-in processer (almost 100):
 Vector and geometric analysis
 Raster based
 Conversions processes (raster  vector)
 Tight integration with local data and map rendering
