Where to Find Layer URLs

To find georeferenced maps and their associated XYZ or WMTS URLs, browse our brief list of georeferenced layers available for reuse. Alternatively, go to our Explore georeferenced maps viewer to browse our maps and select the blue Overlay tab in the footer for your chosen map:

If you select the blue Overlay tab in the footer of the Explore georeferenced maps viewer, the first link in the popup box will take you to a home page appearing like this below (see, for example, the Bartholomew half-inch 1940s layer). Many of our georeferenced layers have home pages in this style, with links to the WMTS and XYZ URLs to the upper right:
