A better MAX Light Rail map - a photo on Flickriver

View full size

Unlike the official map, this one is geographically correct (At full size, 1 pixel=100 feet).

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:
(((Longitudes*256198)+31510062)/100)+10
*256198: convert to feet (from this calculator, using average of the top- and bottom-most latitudes)
+62766218: Move the data points so the lowest values are zero (this makes the base/origin be 0,0)
/100: Shrink image
+10: Create whitespace/border area, so that the paths do not go to the edge of the image

and 430-(((Latitudes*364641)-16587582)/100).
Similar, but using "430-" instead of "+10" since Y values in SVG start counting from the top instead of the bottom

This map is also available in SVG format at Wikipedia
