The main objects

  • Reduce the burden of data-reporting in the municipalities

  • Increase the quality of the data


Relevant data

  • Geo-referenced data that municipalities are obliged to report to Statistics Norway once a year

  • Examples

    • length of footpaths and bikeways established within urban agglomerations last year

    • different kinds of green areas

    • sewerage systems, pipes, .., length, age, types of material, ..

    • ---


Today’s problems

  • Un-standardized

    • data storage

    • data format

  • Some municipalities don’t have GIS

  • The municipalities officers in charge understand the questions different

    • ex. within/outside urban agglomerations

  • Impossible to know the quality of data


The ”ideal world” of data-catching

  • Standard formats

  • Open systems, platform independency

  • WFS – Web Feature Service (or Server)

    • The Web Feature Server (WFS) is an interface allowing requests for geographical features across the web being highly interoperable. It uses the XML-based GML for data exchange

  • The basic Web Feature Service allows querying and retrieval of features (http)

Work plan- 2006

  • Establish a simple WFS for points in The National Mapping Authority

  • Contact one or two vendors of GIS for implementing WFS

  • Create receiving routines for transforming GML to ArcSDE
