Hi, mappers, I'm trying to create a list that highlights interesting projects and transformative uses for maps. Do you have a favorite you'd be willing to share with me? Here are a few that I like to give you and idea of what I'm looking for. Atlas of the Historical Geography of the United States<http://dsl.richmond.edu/historicalatlas/> British First World War Trench Maps<https://maps.nls.uk/ww1/trenches/> Virtual Shanghai<https://www.virtualshanghai.net/Maps/Presentation> USGS Historical Topographic Map Explorer<https://livingatlas.arcgis.com/topoexplorer/index.html> Thanks for your help with this.
