Not sure how to get a map onto your computer's hard drive?  Try this:

Right click on the map you want.  Look for something like, "Save image as..." and click (left click) on that.  You will probably be asked to name the file as you wish.  The name it already has goes something like this: "lo_" stands for Lake Oswego (quadrangle), a1 (or b2, etc) stands for the segment, and the "x" means the file is "extracted" from a much larger file (to make your download times more reasonable).

The above maps have been updated (January 2002) and extended south to the city limits.  The pedestrian routes on these maps are color coded according to quality.  (These are larger files than in the past: download times will be a little longer.)  Map B3 has been extended to the east to the river edge.

Keep an eye on this page.  We will, for each of the segments, post descriptions of points of interest ("Curiosities").

A composite map that combines A1, A2, A3, B1, B2, and B3 and which prints on an 8-1/2 X 11 sheet (the JPEG file is 906 kB) can be downloaded HERE (for viewing) or from HERE (for printing)

Want to see one of the other (unfinished) segments?  E-mail us and we will post it.   NOW
We have other areas mapped too, and can post some of them.

These GIS maps are the planner's maps that often don't distinguish between constructed streets and "paper" streets, those rights of way owned by the city but not developed into real streets.  They can be confusing and not very useful for route finding.

Explore Portland!'s maps have been made to solve this problem.
 

This is well worth the effort to learn to use.  It's an incredibly rich resource.
