Crop individual regions from CONUS.

2 Basemaps Needed

Order of Operations

  1. Download CONUS data
  2. Convert palette
  3. Convert projection
  4. Add basemap
    • For CONUS
      1. resize to 450px width
      2. add basemap-450.png
    • For Regions (assuming no resize necessary)
      1. add full-width, CONUS basemap
      2. crop regions into 450px chunks

Basemaps should not be resized, they should be at final output size as they do not resize well, especially after Twitter compression.
