Eileen O. Hokaasen / Ola Nordbeck Geodata-infrastructure a battle between Open Source and Commercial software Eileen O. Hokaasen / Ola Nordbeck eoh@ssb.no / oln@ssb.no EFGS October 2009

Today ssb.no F I R E W A L Statbank Statistics External WMS/WFS providers ssb.no F I R E W A L ArcGIS coverages, shape files etc. Norway Digital Desktop GIS programme Statistics Norway SAS Central register of Establishments and Enterprises SN-Cadastre NE Statistics Statbank Statistical base registers Statistical Population Register

Challenges IT resources – or rather the lack of these Lack of knowledge “Marriage” to ESRI products Established Oracle environment Connection/link to other databases

Alternative 1. Open Source ArcGIS coverages PostGIS Geodatabase Communication tools: ZigGIS/OGC Existing Desktop GIS programme: ArcGIS Communication tools: FWTOOLS (OGR), GeoTools, FME Existing Oracle Statistical base registers Desktop GIS programme: QGIS uDig MapWindow Grass Etc.

Alternative 2. Open Source and Commercial ArcGIS coverages PostGIS Geodatabase Communication tools: ArcGIS Server Existing Desktop GIS programme: ArcGIS Communication tools: FWTOOLS (OGR), GeoTools, FME Existing Oracle Statistical base registers Desktop GIS programme: Manifold QGIS uDig MapWindow Grass Etc.

Main factors for choosing alternative 3 Alternative 1 and 2 - + Statistics Norway, not user of Postgresql (PostGIS) today No or small license costs for PostGIS No GIS administration unit within Statistics Norway Limited group of full time GIS users Trained ArcGIS users No or small license costs for Manifold or Open Source Desktop GIS Many infrastructure components Many build-on possibilities of other Open Source components Limited functions for GIS analysis on server and Desktop GIS Alternative 3 - + License costs, but less important due to existing licenses Statistics Norway, An Oracle Environment License costs ArcGIS users Not possible to make full and easy use of GIS analysis functions in Oracle Spatial using ArcGIS Good functions for GIS analysis on server and Desktop GIS Established routines for working with ArcGIS and SAS Streamlined infrastructure, few components Possible to connect Manifold or Open Desktop GIS to Oracle and make use of Oracle GIS analyses functions

Discussion Experience of geodata-infrastructure planning Geodatabase Open source vs. Commercial alternatives Desktop GIS Experience of work with Open Desktop GIS Manifold, not open source but low cost and better communication with geodatabase Supermap?
