GSoC 2009 idea for GeoReport accepted!!!

We are very proud to announce that GSoC 2009 accepted the idea proposed by INOVA and GeoSOA !!
Giovanni Onofri, computer engineering student from Italy, will go to Canada very soon to start the project toghether with GeoSOA Group!! His mentors will be Thierry Badard, Eitenne Dube from Canada (GeoSOA) and Fabio D'Ovidio from Italy (INOVA)!


The idea is to contribute to the development of GeoBI integrating GeOLAP module in GeoReport by using Sptialytics and Pentaho CDF with the aim to set and create GeoDashboards as easy as possible both for multidimentional cubes navigation and for charts, diagrams, indicators displaying directly from the map!

The aim is to improve CDF MapFishComponent written by INOVA and use\improve the CDF Pivot Component in order to set:
  • a pivot for (alphanumeric) cube nabigation
  • a map for cartographic data display and spatially navigation of multidimensional cubes through DRILL DOWN and ROLL UP operations
  • BI processes (xactions) to display diagrams, charts and indicators on the map by clickking cartographic features
  • the interaction between pivot and cartographic map by setting both listeners and parameters in order to switch from pivot to map and viceversa
The integration work will develop by defining small integration steps to be acheived in order to consistently merging capabilities provided by the the different tools.

In particular the following applications will be used:
  • GeoMondrian
  • Spatialitycs
  • GeoReport
  • GeoServer
  • OpenLayers
  • Mapfish
  • Pentaho CDF
  • PentahoBI platform
and the following technologies will be used:
  • JavaScript + ExtJS
  • JAVA
  • JSP (Java Server Pages)
  • GeoJSON
  • OGC WFS protocol
  • OGC WMS protocol
  • MDX
  • SQL
  • XML

It might be a good idea to see how to implement the OpenLayers cluster strategy for point representation...

http://dev.openlayers.org/sandbox/vector-behavior/examples/strategy-cluster.html

http://dev.openlayers.org/releases/OpenLayers-2.7/doc/apidocs/files/OpenLayers/Strategy/Cluster-js.html

In a way, it can emulate "Geo" DRILL DOWN and ROLL UP while zooming in and out.

The cluster can be used in conjunction with the BBOX strategy to filters out the features depending on map extents and therefore to improve client performance
