I've been playing with AllMaps to georeference SLV maps that are available via @IIIF. Here's a set of maps of the Melbourne CBD created for fire insurance in the 1920s. https://viewer.allmaps.org/?url=https%3A%2F%2Fannotations.allmaps.org%2Fmanifests%2F628c216109f482f1 Hold down 'b' to remove the map backgrounds & see the buildings more easily. #GLAM #libraries #digitalHumanities #maps
