DjangoCon 2011 – Making interactive maps for the web

For the last regular talk of DjangoCon US 2011 we’ll be hearing from Zain Memon on “Making interactive maps for the web”.

When tasked with displaying geo-data, most developers decide to put some big red markers on an embeddable Google Map and call it a day. If you’re interested in creating maps that are more beautiful, more interactive, and more usable, this talk is for you.

Good maps are…

  • Attractive (Nice looking things do better. People like it more)
  • Readable (Need to make the data pop more than the maps.  Pale Dawn or Midnight Commander)
  • Interactive (Hover states. Polygons on more information. Selecting + Filtering)
  • Fast (Tile your map, don’t use a lot of polygons)
