Summary[edit]

Description

Geographically correct Portland Streetcar map with stop names 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)+62691308)/25)+125

  • -122: Remove whole number (entire map has same longitude integer)
  • x256198: convert to feet (from this calculator)
  • +62691308: Convert to positive numbers
  • /25: Shrink image
  • +125: Shift path over

and 583-((((Latitude-45)*364641)-180120)/25)

  • 583-: SVG y-axis starts at the top and not the bottom
