tbadard writes "After the release of a new version of its open source spatial ETL tool, GeoKettle yesterday (please see the announcement for more details), the GeoSOA research group at Laval University, Quebec, Canada is proud to announce the availibility as new open source projects of GeoMondrian, the first implementation of a Spatial OLAP (SOLAP) server and Spatialytics, a lightweight cartographic component which enables navigation in SOLAP data cubes. GeoKettle, GeoMondrian and Spatialytics are components of the complete geospatial BI (Business Intelligence) software stack developed by the GeoSOA research group."
The rest of the announcement below, including precision about GeoMondrian and Spatialytics.
"GeoMondrian:
GeoMondrian is a "spatially-enabled" version of the open source Mondrian OLAP server (also named Pentaho Analysis Services) developed by Pentaho. To make it clear, GeoMondrian is an implementation of a Spatial OLAP (SOLAP) server. As far as we know, it is the first implementation of such a server and it is open source!
It adds to Mondrian a Geometry data type, enabling storage of member properties and measures containing vector geometries (points, lines, polygons) natively within the data cubes. Some MDX extensions supporting this data type are also provided. They allow to add spatial analysis capabilities to the analytical queries.
GeoMondrian provides then a consistent integration of spatial objects into the OLAP data cube structure, instead of fetching them from an external spatial DBMS, web service or a GIS file. To summarize, GeoMondrian brings to the Mondrian OLAP server what PostGIS brings to the PostgreSQL DBMS, i.e. a consistent and powerful support for geospatial data!
Spatialytics:
Spatialytics is an open source lightweight cartographic component which enables navigation in Spatial OLAP (SOLAP) data cubes. It aims to be integrated into existing dashboard frameworks in order to produce interactive geo-analytical dashboards. Such dashboards support the decision making process by including the geospatial dimension in the analysis of enterprise data.
Spatialytics is based on the OpenLayers web mapping client, and uses olap4j for connection to OLAP data sources. For now, it requires GeoMondrian, the first implementation of a Spatial OLAP (SOLAP) server, to be able to display members of a geospatial dimension on a map.
Spatialytics allows then:
GeoKettle, GeoMondrian and Spatialytics have already been adopted by some organisations, as for instance by the GeoBI project. GeoETL is GeoKettle, GeOLAP is GeoMondrian and GeoReport will soon benefit from Spatialytics capabilities (a student funded by the Google Summer of Code 2009 program, under the umbrella of OSGeo, is currently working on this task at Laval University).
I hope you will enjoy GeoKettle, GeoMondrian and Spatialytics. If you require more information about these open source geospatial BI software components, please visit the projects' pages and do not hesitate to contact us through the mailing lists or directly."

Spatialytics allows then:
- the connection with a Spatial OLAP server such as GeoMondrian
- the navigation in the geospatial data cubes
- and the cartographic representation of some measures and members of a geospatial dimension as static or dynamic choropleth maps (for now)

GeoETL is GeoKettle, GeOLAP is GeoMondrian and GeoReport will soon benefit from Spatialytics capabilities (a student funded by the Google Summer of Code 2009 program, under the umbrella of OSGeo, is currently working on this task at Laval University).

GeoKettle 3.2.0 Released
[+]
The open source ETL tool GeoKettle released version 3.2.0.
GeoKettle is an Extract, Transform and Load tool, and so is the also open source Spatial Data Integrator and the popular Safe Software's FME.
From the entry: "What is new since release 3.1.0-20081103?
* The GeoKettle extensions were ported to the new Pentaho Data Integration (PDI) version 3.2.0-stable. As such, this release of GeoKettle includes all the improvements from the new PDI version.
* Added a "GIS File Output" step. At present, this step supports the writing of Shapefiles
* Added support for Spatial Reference Systems (SRS). SRS metadata was added to ValueMeta for Geometry fields. Steps allowing to set a SRS ("Set SRS") and transform coordinates (reproject) of geometries from one SRS to another ("SRS Transformation") have also been developed. The SRS support is based on GeoTools' implementation of coordinate reference systems (org.opengis.referencing package) [...]"
