[OSGeo-Discuss] The open source geospatial BI components GeoMondrian and Spatialytics are available!
Hello, After the release of a new version of its open source spatial ETL tool, GeoKettle (http://www.geokettle.org) yesterday (please see the announcement at http://geosoa.scg.ulaval.ca/en/index.php?module=announce&ANN_user_op=view&ANN_id=12 for more details), the GeoSOA research group (http://geosoa.scg.ulaval.ca) at Laval University, Quebec, Canada is proud to announce the availibility as new open source projects of GeoMondrian (http://www.geo-mondrian.org), the first implementation of a Spatial OLAP (SOLAP) server and Spatialytics (http://www.spatialytics.org), 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. GeoMondrian: GeoMondrian (http://www.geo-mondrian.org) is a "spatially-enabled" version of the open source Mondrian OLAP server (also named Pentaho Analysis Services, http://mondrian.pentaho.org) developed by Pentaho (http://www.pentaho.com). 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 (http://www.spatialytics.org) 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: * 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) GeoKettle, GeoMondrian and Spatialytics have already been adopted by some organisations, as for instance by the GeoBI project (http://www.geobi.org). 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.

[OSGeo-Discuss] PostGIS 1.4.0 Beta 1
The PostGIS team is super happy to announce that a beta release of PostGIS 1.4.0 is now available for download and testing! http://postgis.refractions.net/download/postgis-1.4.0b1.tar.gz The 1.4 series includes a large number of new features, fixes, speed-ups and mini chocolate chip cookies. PostGIS 1.4 is best consumed along side helpings of the latest Proj4 and GEOS libraries: http://download.osgeo.org/proj/proj-4.6.1.tar.gz http://download.osgeo.org/geos/geos-3.1.0.tar.bz2 We appreciate all possible testing and feed-back you can provide to make the upcoming 1.4 release a high quality affair. The sooner we get feedback, the sooner we can release 1.4.0! Here are some more details about 1.4: - API Stability - As of the 1.4 release series, the public API of PostGIS will not change during minor releases. - Compatibility - The versions below are the *minimum* requirements for PostGIS 1.4 - PostgreSQL 8.2 and higher on all platforms - GEOS 3.0 and higher only - PROJ4 4.5 and higher only - New Features - ST_Union() uses high-speed cascaded union when compiled against GEOS 3.1+ (Paul Ramsey) - ST_ContainsProperly() requires GEOS 3.1+ - ST_Intersects(), ST_Contains(), ST_Within() use high-speed cached prepared geometry against GEOS 3.1+ (Paul Ramsey) - Vastly improved documentation and reference manual (Regina Obe & Kevin Neufeld) - Figures and diagram examples in the reference manual (Kevin Neufeld) - ST_IsValidReason() returns readable explanations for validity failures (Paul Ramsey) - ST_GeoHash() returns a geohash.org signature for geometries (Paul Ramsey) - GTK+ multi-platform GUI for shape file loading (Paul Ramsey) - ST_LineCrossingDirection() returns crossing directions (Paul Ramsey) - ST_LocateBetweenElevations() returns sub-string based on Z-ordinate.
