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/)

• Library of Congress Map Collection (https://www.loc.gov/maps/)

• USGS Historical Topographic Map Explorer (https://livingatlas.arcgis.com/topoexplorer/index.html)

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:
