Transcript

  • 1. Public sources in Estonia
  • 2. OSM in Estonia
    First data – 23.07.2006, by LA2 (Sweden)
    Tartu city import – 2009 January
    NGO formalized – 2009 August
    To rise money
    To have legal body for parties
    Corine Land Cover import – 2009 October
    Official administrative borders
    NGO Project grant (~26.000 €): 2010-11
    Localized global map with own servers
    Local language support
    Combination of OSM data with OSM-incompatible data
    Community development, mapping parties
  • 3. Why import?
    Small population density
    Estonia: size of Netherlands, population 1.3 M
    Some cities not covered yet by volunteers
    Some roads/areas are very rarely reached by mappers
    Opportunity
    Public datasources are available, good IT level by state
    State organization is not too large,
    E.g. public WMS by National Land Board
    Our result
    About 2/3 of Estonian OSM is currently imported
  • 4. Possible Sources
    Two technical types:
    Vector data
    On-line services (WMS)
    State government
    National Land Board
    Ministeries
    Municipalities
    State agencies
    E.g. Environmental, nature protection
    Companies
    Could be handlers of public data
  • 5. Issues
    License – what licence?
    Our data is in Internet, why don’t you just use it?
    Do not know difference between:
    access openess
    usage rights
    Hard to access state by private person
    Official requests, permissions
    Formal rules by state prefer legal entities
    Strange cases
    We already gave our data to X company, we do not want to mess with this again.
  • 6. Issues 2
    Law of geospatial data
    State tries to monopolize all geodata handling
    Legal know-how needed to be involved in the process
    State official position
    Must follow the rules. If no rules, cannot do anything
  • 7. Extra data
    We have got also permission to use:
    Aerial imagery
    DEM model data
    Where to put them?
  • 8. Suggestions
    Socialize and network (without Internet)
    Formal NGO is useful to speak with state
    Import
    Import as little as possible (but as much as needed)
    Where existing data has very little value, so it can be discarded safely
    New datasets with no existing data, e.g. buildings
