This is a Working Group started by the Public Geospatial Data Committee.

While OSGeo can consider hosting sets of public geodata, (and for the purposes of offering maintained packages of high-quality data for education and demonstration, it probably will), we can compile a set of best practises and references to good prior art for building and maintaining collections of data and metadata.

Focus

  • Metadata for collections of geographic information.
  • Providing best practise and prototypes for geodata search facilities
  • Help with providing input into the OSGeo repository/services at http://osgeo.telascience.org/
  • Providing 'catalog'/discovery/search services as part of OSGeo activities in promoting access to public domain and open licensed bodies of data.

Participants

Existing (Meta) Search Projects and Related Efforts

Search Services:

  • (Meta) Data Catalogues / Data Repositories
    • Mapdex is "a global Index of 2,018 servers, serving 37,168 map services, containing over 400,000 GIS Layers, covering more than 4,000,000 columns!"
    • GeoTorrent hosts BitTorrents of shapefile/TIFF format data.
    • GeoNetwork "Find Interactive Maps, GIS datasets, Satellite Imagery and Related Applications"
    • DLESE Collection System offers a metadata repository and editor
    • Geo Meta Data Base (GMDB) metadata repository and editor based on ISO 19115 Metadata Core with XML export to ISO 19115 CH-Profile/GM03 (german only)
    • GDI Portals (country specific): US, UK, D, A, CH, LI, F, ...
  • (Meta) Search Engines:
    • geometa.info - search engine for geospatial services, data and documents combining structured and unstructured data (currently german only)
    • Google search using 'allinurl' parameter

Lists:

Public Datasets for Possible Mirroring or Distribution

Gazetteer Data

... basically placenames with coordinates ...

Vector data

  • VMAP0 - 1:1Mio, very generalised vector data for many features, around 70 layers
  • GSHHS - world coastlines, different scales available
  • TIGER/Line (USA) - street and addressing data for the US
  • RNF (Canada) - street and addressing data for Canada
  • OpenStreetMap - data available through a HTTP based XML interface. They've also been getting requests for shapefile and GML output of their data.

Raster data

Wishlist for Public Datasets
