First, we'd encourage you to take a look at the GIS Mapping and Geospatial Data research guide that is filled with u-to-date content/information/tips on how to use GIS software, finding geospatial data, and other mapping resources.
You can book a research appointment with our map specialists here. This team is made up of mapping assistants, led by our GIS/data informatics librarian, Bruce Boucek. You can also contact them at mapping@gsd.harvard.edu.
You can also make a one-on-one consultation with Bruce here!
