Description

Map of the TriMet MAX Light Rail system in the Portland, Oregon metropolitan area. Unlike the official map, this one is geographically correct.

Made using official TriMet data that's been made publicly available for Google Transit and others. Data was loaded into a spreadsheet and converted to SVG coordinates using the formulas:

((((Longitude-122)*256198)+62766218)/100)+10

  • -122: Remove whole number (entire map has same longitude integer)
  • x256198: convert to feet (from this calculator)
  • +62766218: Convert to positive numbers
  • /100: Shrink image
  • +10: Create border area

and 430-((((Latitude-45)*364641)-178737)/100).

I created this work entirely by myself.
