Web mapping

What are the components that make up a typical web map?

Base Map

  • Static data* that is always present
  • Zoom levels 0-21 affect presentation
  • Zoom level styling file:  CartoCSS, Mapnik XML
  • Tools for styling: Tilemill, Mapbox Studio Classic

*This is changing with vector tiles, but we won't go into that tonight

Made of tiles!

  • 256px X 256px
  • Same boundaries

Behind the curtain...

Zoom Level: 0

Zoom Level: 1

# of tiles increase by a factor of 4 for each zoom level

  • z0 = 1 tile
  • z1 = 4 tiles
  • z2 = 16 tiles
  • ...
  • z15 = ~1.1 billion tiles
  • z17 = ~17 billion tiles

Zoom Level: 0

Zoom Level: 3

Zoom Level: 7

Zoom Level: 12

Where can I get data?

How does this all come together to make a map?

It's complicated.

You don't have to do all this.

Web Mapping Platforms

Leaflet

  • JavaScript library that:
    • Grabs tiles for your basemap
    • Adds points, lines, and/or polygons of your feature layer
    • Handles interaction
  • Extended with several plugins for greater functionality

Mapbox

  • Mapbox Editor
    • Simple, GUI-centered mapping platform
  • Tilemill/Mapbox Studio Classic
    • Create your own basemaps!
  • MapboxJS
    • Extension of Leaflet
    • Access Mapbox services
  • And LOTS more... 

Mapbox Editor

Tilemill/Mapbox Studio Classic

Tilemill/Mapbox Studio Classic

CartoDB

  • All-in-1 mapping platform
    • Data
    • Styling
    • Interaction
  • No database setup!

Get user generated data!

  • Different mapping approach than previous examples
  • SVG-based
  • DOM manipulation
  • Great interaction, styling and transitions
  • Not exclusively for mapping
  • Very powerful

Let's make some maps!
