Mapbox and Georefencer

Our goals today are to learn how to use Mapbox Studio to create datasets, tilesets, and styles. We'll also practice georeferencing a map with Georefencer.

Mapbox Studio

  • Create an account on Mapbox and sign into studio.
  • Download the GeoJSON for the Berlin Wall and save as a file on your computer.
  • Click on Datasets and then "New Dataset." Upload your Berlin Wall data set and name it appropriately.
  • After you've created a data set for the Berlin Wall, create a tileset
  • Finally, create a Style and add your layer to the map.

Georefencer

  • Select a public domain map to georeference. If you do not have a map selected, try selecting from among the Old Maps of Berlin on Wikimedia Commons. Be sure to save the map in its original (highest) resolution.
  • Create an account on Georefencer and sign in.
  • Click on Compare and Overlay and upload your map.
  • Use the georeferencing tool to select control points on the base map as well as your historical map.
  • When the tool tells you that you have sufficient points, click on "This Map" and "Export to GeoTIFF." The process of conversation takes time; you'll be alerted by email and on the website when it's finished.
  • After downloading the file, upload your GeoTiff as a Tileset to Mapbox and add it as a layer to your Style.
