Spatialytics is proud to announce the immediate release of Spatialytics OLAP 1.0 and GeoMondrian 1.0. Spatialytics OLAP (and its open source edition named GeoMondrian) is a Spatial OnLine Analytical Processing (Spatial OLAP or SOLAP) server, a spatially-enabled version of Pentaho Analysis Services (aka. Mondrian). As far as we know, it is the first implementation of such a server!
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 functions supporting this data type are also provided. They allow to add spatial analysis capabilities to the analytical queries, and hence to produce true geo-analytical queries. Geometry objects are handled using the JTS library. At present, only PostgreSQL with the PostGIS spatial extension is supported as a data source for Geometry values but other spatial DBMS should be supported soon.
Spatialytics OLAP 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, Spatialytics OLAP brings to the Mondrian OLAP server what PostGIS brings to the PostgreSQL DBMS, i.e. a consistent and powerful storage and querying for geospatial data!
GeoMondrian is released under the terms of the EPL 1.0 licence.
In the last few months, many bug fixes, enhancements and new features have been brought in order to produce this first stable release of Spatialytics OLAP and GeoMondrian. Among many other things, it could be mentioned:
