Workshop: Finding and Georeferencing an Historical Map
Explore one of the databases discussed in the presentation and download an historical map of interest (or use one of your own if you already have one!). Then, using the MapWarper online tool, georeference your map with at least 4 points.
Possible Mapping Geodatabases
David Rumsey Map Collection (https://www.davidrumsey.com/)

Redlining Map Option
To look at your data against an historical Boston redlining map, we recommend using one of the "Residential Security Maps" from the Boston Public library.
Georeferenced version of the redlining map:
