Map making for Cartographers

  1. 1. … Thank God!  Denis Wood, 2003 … Long live the map makers.  Ed Parson, 2008
  2. 2. The ‚map stack‘ Server Web  Browser UI Server Tile Tile Cache Map Server Application Server Geospatial Data http://www.alistapart.com/articles/ takecontrolofyourmaps
  3. 3. The ‚map stack‘ Server Web  Browser UI Server Tile Tile Cache Map Server Application Server Geospatial Data
  4. 4. The ‚map stack‘ Server Web  Browser UI Server Tile Tile Cache Map Server Application Server Geospatial Data Source: Microsoft Virtual Earth SDK
  5. 5. The ‚map stack‘ Server Web  Browser UI Server Tile Tile Cache Map Server Application Server Geospatial Data
  6. 6. The ‚map stack‘ Types of web  Server Web  Browser UI mapping services proprietary Server Tile Tile Cache open source commercial Map Server Application Server Geospatial Data
  7. 7. Proprietary web  mapping services Server Web  Browser UI Server Tile Tile Cache Map Server Application Server Geospatial Data
  8. 8. Proprietary web  mapping services How to add data Server Web  Browser UI Gadgets API KML, GeoRSS, … Server Tile Tile Cache Image overlays Own tiles + Map Server Application Server Geospatial Data
  9. 9. Proprietary web  mapping services Why using them? Server Web  Browser UI quick setup API intuitive interface Server Tile Tile Cache accessible by everybody with an internet browser availability of a huge Map Server Application amount of geo data Server many thousands of servers Geospatial Data
  10. 10. Proprietary web mapping services Limitations Server Web Browser UI pre‐rendered map tiles API no access on vector data Server Tile or 3rd dimension Tile Cache Mercator projection limitations according to Map Server Application API options Server licensing issues Geospatial Data
  11. 11. A cartographer‘s options comparing tiles of  different vendors optimizing overlay quality using region functionality for scale dependent results optimizing data and user  interface for user needs
  12. 12. Basic cartographic issues A cartographer‘s options What’s the purpose of the map? comparing tiles of  different vendors Who is the user? optimizing overlay quality Readability using region functionality Visual Hierarchy for scale dependent results … optimizing data and user  interface for user needs
  13. 13. Open source web mapping services Server Web  Open Layers, Modest Maps Browser UI Server Tile Er, Tile Cache Tile Cache UMN MapServer Map Server Application Server Geospatial Data OpenStreetMap Data
  14. 14. Why using them? creating own map tiles and/or map tiles from proprietary vendors programming own functionalities data on own servers http://www.sander-partner.ch/be/en/Nawa/index.html vector functionality offline‐ and intranet  usage possible http://chicago.everyblock.com
  15. 15. Limitations more complex setup more programming limited server capacities http://www.sander-partner.ch/be/en/Nawa/index.html http://chicago.everyblock.com
  16. 16. Conclusions Web mapping services are not only tools for non‐expert map makers Cartographic principles can also be applied in  geobrowsers A good knowledge of available tools is important to pick the right solution for a certain use case
  17. 17. BUT: Cartographers should actively contribute their ideas and principles to the world of web mapping.
