I have a map/architectural drawing of two floors of a huge building with a lot of rooms. Now I'd like to make an interactive slippy map using preferably Leaflet showing all the rooms and use markers/polygons showing what happens in each room and who's sitting where, etc. These markers should quite easily be editable.
Does anyone have any ideas of how to make this happen? First I was thinking about just pretending house covers the whole world and then use standard web mercator with
Another idea is to use zoomify together with Leaflet.
The problem with both methods is that it's difficult to get right coordinates. Best would be to use some kind of a local projection.
