A "Location" already has latitude/longitude coordinates.
But I am also looking for a way to precisely locate locations on a self-created map. It would be useful for finding printers in a large open-space or indicating (to a newcomer) where a specific room is: theses examples won't work with "latitude/longitude coordinates", but "pixels coordinates" on a uploaded JPEG/PNG/SVG image would.
In a context of IOT some devices it's far of the Central TI Deparment, so its very important know the location for maintenace, search, find and fix or replace.
Google maps, Open Street maps or something like map jams integration will be nice...
We have some projects to add this in short term
I Find this interesant... https://github.com/mohierf/glpi_maps
OpenStreetMap integration is being done here : https://github.com/glpi-project/glpi/pull/3336
This should be ok for GLPI 9.3
