The following commentary was prepared by this site's Webmistress.
- The current land plat book, available from the Clarion County Courthouse (Clarion, PA 16214), is an inexpensive and excellent resource for tracing the present-day location of land.
- County and township road maps are available from the County Road Superintendent, Clarion County Courthouse, Clarion, PA 16214.
- Charles
Reeves, a professional cartographer whose hobby is genealogy and
history, designed some of the outstanding maps found on this site. He
recently wrote,
I have ordered the US Census files for all of the US. So, I will be able to do any county in the U.S. with detailed street and landmark info, if desired. I did your Clarion Co. map from USGS data I downloaded, which doesn't include attribute names (streets, landmarks, etc.).
Please contact Charles about your mapping needs -- your own research, books you're writing, family reunions, etc. His work is outstanding, and his prices are extremely reasonable. He can do maps of just about anything you want!
Also, the USGS is uploading their 7.5 degree (1:24,000 scale) DEM (Digital Elevation Model) data to their FTP site. I used the 1:100,000 data to generate the relief map of TN. This means that I will be able to create much higher resolution relief maps. I'm also looking at a program that will automatically generate 3D terrain images from these data, as well as fly-through QuickTime 3D movies.
