This content on this website is the result of a crowdsourcing pilot project that took place early 2022. About
70 people signed up, and over half of them helped to process the maps in some way. Over four months, 1,500 individual sheets
from 270 different Sanborn atlases were georeferenced. You can read more about the project in the about
page, or read a lot more about it in my master's thesis:
"Creating a Public Space for Georeferencing Sanborn Maps". Thanks!
