Is it possible to use a historical map as a base layer for Neatline without going through the process of adding georeferences to the file? Or let’s say you had a map of a fictitious place from a novel which really can’t be georeferenced. I added a tiff file without georeferences to our geoserver, but then when I tried to add it to a share in the Geoserver admin consule there did not appear to be an option for adding files without spatial data.
