Summarized needs[edit]

  • Installation of the tileserver environment
  • Embedding OSM maps on Wikipedia pages
  • Enabling an environment for creating data driven maps
  • Handling geospatial data in Wikimedia
    • Practices for (geo)data mass uploads: / bots / community / maintenance
  • "Wikimaps" becoming a term for maps in Wikipedia. Not an umbrella. A thematic glue. Maps & geodata community.

Presented projects[edit]

1. Maarten Dammers: Map content donation

2. Limes Project (Barbara Fischer)
The challenge is the provide the resources to be able to interact with for example OSM in order to be able to be able to integrate interactive maps into WP articles. Taking account that maps are to be considered as valuable knowledge store as text or image the task should welcome some emphasis.

3. Interesting project (but nobody related present)

4. Wikimaps guidelines, Locator maps automatic generation project (Hugo Lopez)
Out of 8 years of map making by Wikipedia's volunteers cartographers, the following map families and associated guidelines have been gathered:

5. Wikidata & Maps (Daniel Kinzler)

6. Gradiants Maps (Maarten Dammers~ Multichill) Would be cool if this would make possible! Possible datasource for admin levels: naturalearthdata Other source: OpenStreetMap - WIWOSM
