SDW working group charter

  • to determine how spatial information can best be integrated with other data on the Web;
  • to determine how machines and people can discover that different facts in different datasets relate to the same place, especially when 'place' is expressed in different ways and at different levels of granularity;
  • to identify and assess existing methods and tools and then create a set of best practices for their use;
  • to complete the standardization of informal technologies already in widespread use.

Who are we trying to help?

  • Everyone - because spatial data is really useful! …
  • But we really need to focus on the gatekeepers:
    • Web developers
    • Spatial data custodians & publishers

  • 1.4 (4) Publish details of fixed assets (e.g. dikes & dams, buildings, roads, critical infrastructure etc.) and topographical features (e.g. water bodies)
  • 1.5 (5) Publish census data which contains population statistics for each administrative area
  • 1.6 (6) Publish the evacuation plan
