How can I find the source and vintage of each data layer?
The credit legend, in the lower left-hand corner of the map face, provides a short summary of sources and data currency.More detailed source information is in an XML metadata file attached to each GeoPDF file. This file contains series-level, quad-level, and layer-level metadata, but US Topo does not preserve or track feature-level metadata. See the US Topo Map and Historical Topographic Map Users Guide for information about this file.
