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

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

  3. Desktop GIS programme SAS Planned geodata regime External WMS/WFS providers WMS ssb.no F I R E W A L L ArcGIS coverages Geodatabase Statistics Norway Norwegian Mapping and Cadastre Authority Local Cadastre Copy Statbank Statistical base registers Statistics Municipalities

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

  5. System specification: Geodata-infrastructure components

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

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

  8. Existing Desktop GIS programme: ArcGIS Desktop GIS programme: Manifold QGIS uDig MapWindow Grass Etc. Alternative 3. Commercial ArcGIS coverages Geodatabase Communication tools: ArcGIS Server Existing Oracle Statistical base registers

  9. Main factors for choosing alternative 3

  10. 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?
