Selective Digitization

Due: 2/12

What

Research and obtain a scanned map, georeference it, and then digitize selected features in order to produce a new map that has a different focus or narrative. Design a map composition that shows the georeferenced map and your new map of digitized features side by side.

Requirements

• Your final work must be a designed map composition with two maps (your georeferenced map and your new map of selectively digitized features) on a single slide with a 16:9 aspect ratio (1920x1080 pixels).

• You are encouraged to select one of the map examples discussed thus far during class (either in lecture slides or during a group exercise) and imitate its graphic style when designing the map of digitized features. To questions about map design from class on 2/5: this is the best way to learn and practice designing beautiful maps.

• Your designed map composition must include:
  • title
  • legend
  • scale bar (or two depending on whether you show your map at the same scale…)
  • north arrow (your map doesn’t need to have north pointing vertically…)
  • citations for all data sources (please use Chicago style or an equivalent)
  • projection used
  • your name

Submission

• Upload your map:
  • as a pdf to Canvas
  • add it to the pin-up Google Slides presentation for 2/12 in the course Google Drive folder
