Google Summer of Code has finished today and, thanks to Giovanni Onofri,
GeoSOA and INOVA the GeOLAP module prototype has done!

Hello,

To complement the message sent by Fabio, here are some details:

Giovanni has spent his Google Summer of Code (GSoC) at Laval University, Canada in the GeoSOA research group (http://geosoa.scg.ulaval.ca) in collaboration with Inova. I was the OSGeo/GSoC mentor of Giovanni. He has acheived a first integration of Spatialytics (http://www.spatialytics.org, which will be renamed as SOLAPLayers in the next few weeks due to another announcement to be done by mid September ;-) ) into Pentaho CDF (Community Dashboard Framework). As a reminder, 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 better 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 (http://www.geo-mondrian.org), 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:

• 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 and proportional symbols (for now)

The integration work performed by Giovanni during his GSoc allows to display the Spatialytics cartographic component together with a pivot table component in a dashboard. Synchronisation between the map and the pivot table have been implemented in the two ways (e.g. a drill down on the map results in a drill down operation in the table and vice versa). This first integration requires further work in order to more properly and consistently integrate the Spatialytics component into CDF but the work performed by Giovanni is a good and promising first step towards the design of a highly customisable and flexible geo-analytical dashboard framework. A live demo of the integration work performed by Giovanni will be available shortly on the GeoSOA website (http://geosoa.scg.ulaval.ca). The source code would also be available in the next few days/weeks in the GSoC 2009 repository.

Cheers,

Th.

Hello Thierry,
thank you very much for your post.
I was waiting for the final report (that Giovanni will post asap) in order to give more details to the list. I think you expleined the whole work very well and I agree with you: it is the first step for a more customisable and flexible geo-analytical dashboard framework!

Thank you again to Giovanni and your group collaboration!!


Fabio
