Topographic Maps
USGS topographic maps of San Diego County, some nearby counties and
the Lake Tahoe area have been
downloaded from public-domain sources, cleaned up and posted here:
These maps are also available on CD-ROM. Just E-mail the webmaster at
pje@efgh.com
and provide a mailing address in the United States. The CD-ROMs will be mailed
to you.
A few topographic maps of the area in and around Jeannette, Pennsylvania
(where I lived many years ago) have also been posted here:
Many of the topographic maps are hard to use because they don't show
major highways built after they were last updated. I have modified a
few of them by overlaying some of the newer streets and highways.
The results have been posted here:
