Hello PostGIS - Community for everybody who is interested in storing 3D city models based on the OGC standard CityGML in an DBMS, I would like to annouce the release of the 3D City Database for PostGIS.
Further information, software downloads and the source code repository can be found at: http://opportunity.bv.tu-berlin.de/software/projects/3dcitydb-imp-exp/ or on the official homepage of the 3D City Database http://www.3dcitydb.net (will be updated soon). The relational schema and a tool to import and export CityGML documents were developed by the Institute for Geodesy and Geoinformation Science (IGG) at the Technische Universität Berlin for the last five years. It is free software under the GNU Lesser General Public License Version 3.0. Until now it could only be used on an Oracle Spatial DBMS. Last fall I came to the developers asking if I could write my Master's thesis about the possibilities to port their open source software to the open source DBMS PostGIS. Well, it was possible and now I'm really curious about some reactions of interested users. I'm still "relatively" new to spatial database so I can't say if I have programmed the scripts and java-code in the best way. At least comparing performance tests to the Oracle version looked very good ;) I would also like to thank the developers of PostGIS. Your hard work on PostGIS 2.0 made this all possible. I'm looking forward to the next releases, especially the 3D stuff. Have a nice day!
