We also offer on our data catalog a shapefile, which is an index to the topo maps and indicates the date (year) for the map published. Yes the USGS maps will have slight shifts between them due to the fact that they had to be manually georeferenced. Furthermore, even maps where the alignment between one layer (such as roads) is high, another layer (such as contours) may be low due to the fact that those old maps were printed one color at a time using (I believe) engraved metal plates. The plates did not always line up exactly between printings. =============================== Michael Smith State GIS Manager, Maine Office of GIS State of Maine, Office of Information Technology michael.smith _at_ maine.gov 207-215-5530 Board Member, Maine GeoLibrary Board Member, Maine GIS Users Group State Rep, National States Geographic Information Council State House Station 174 264 Civic Center Drive Augusta, ME 04333-0174 69o 47' 49.5"W 44o 20' 54.5"N Confidentiality Notice: This email message, including any attachments, is for the sole use of the intended recipients and may contain confidential and privileged information.

I knew they existed off the MeGIS site and have been available from UNH for quite some time as I've gone there several times over the years. Mostly I was curious if the individual map's publication date could be had without going there (or to the USGS site). For any other users on this list that use historic quads, the USGS site may have in some cases several copies of the same addition map for you to choose from and that the geo-referenced pdf is equally serviceable and easily read into the application (in my case, Global Mapper), though note a minimal shift in position between each of them. Below are examples (sorry for the overly compressed jpgs) of the MeGIS WMS version, and three USGS geo-referenced pdfs all of the exact same area (circa 1911) and with other data layers visible for positional referencing.

Well done. I may have missed something; however, where can we view the unclipped versions as the map collars contain other information which pertains to each individual 15' quad and the presented metadata <http://geolibportal.usm.maine.edu/geonetwork/srv/en/metadata.show?id=94 0> is general in nature?
