Sanborn Maps

The most complete Sanborn Map collection

Sanborn Maps are a detailed historical source critical to your Phase I research. But did you know that only EDR searches the complete holdings of the original Sanborn library—nearly 1.3 million maps? These maps all you to track the changing landscape and property use for approximately 12,000 American cities and towns from the late 1800s on, right from your desktop. 

Since EDR first invested in the Sanborn collection in the 1990s, we have made a number of technological improvements to how our customers experience the maps. First, the paper maps were converted to digital images, which helped environmental professionals get the reports faster, and in a way that was easy to inject into their reports. More recently, the collection was rescanned at very high resolution then digitally “stitched” together, creating a seamless digital mosaic. This was a huge benefit to our customers; because orders are cropped from one single digital layer, the target property is always in the center of the image, eliminating the need to access adjoining map sheets, reducing cost and review time. Having all the imagery geo-referenced also allows for delivery of a consistent “north up” view, regardless of the cardinal orientation of the original drawing. EDR passes on the right to reproduce the imagery in your project documents for a specific project. Out latest enhancement, the Sanborn Viewer, allows environmental professionals to work with Sanborn imagery through an interactive web tool. 

EDR's Sanborn Search Engine is the only system that allows you to search Sanborn Maps by lat/long and provides instant site-specific search results.
