I created a very detailed map of New Bedford circa 1913
A few years ago, I created a large-scale map of New Bedford by stitching together detailed survey maps from 1913. My goal was simple: I wanted to be able to zoom in and see individual streets, buildings, and points of interest, then zoom back out and see the city as a whole, without having to switch between separate map plates.
The resulting image was enormous, though, and at the time it was never especially practical to use. I finally got around to importing it into GIS software and georeferencing it, matching points on the historical map to their real-world coordinates so the entire thing could be overlaid accurately in Google Earth.
The result turned out pretty cool. As far as I know, this may be the most detailed single, continuous map of New Bedford from that period, rather than a collection of separate plates or maps at different scales.
