Keynote Speaker - Stuart Allan

He spoke of making maps, not data dumps. Make maps that people are willing/want to look at long enough to learn something from the map.

He showed an example of power of map with showing population distribution of slaves in the southern US by Francis Walker in 1874. This map was displayed prominently in Lincoln meeting w/ his cabinet for the first reading of the Emancipation Proclamation draft.

TileMill and CartoCSS by Justin Miller, MapBox

Justin showed use of TileMill and CartoCSS, desktop tool to generate beautiful map from MapBox, MapBox's mantra is "be focus" and do one thing well and do it efficiently. He shared his typical workflow to generate map.

  1. Get Data (geodata)
  2. Import Data into TileMill
  3. Code/Style iteratively
  4. Export into map imagery - (MbTile, PDF, JPEG etc)

Tip: Once can import data into TileMill, one can take raw data from geojson data from GitHub directly.

Paste in Place by Ryan Sullivan

Ryan talked about the importance of sketching, drawing to develop ideas and to work through problems. He uses drawing/sketching to create prototypes and concept driven products. He made a very interesting comment with "Act of making maps is form of service that something producer shares with audiences/public"
