Mapping the InterBC campus, even though it’s a pretty small campus in comparison to others, is proving to be a real challenge.
The main problem is that the emergency floorplans, which are the only source I got at this point, are not very accurate and do not match the building outlines from the existing aerial imagery. Maybe I still don’t know how to use JOSM properly.
For now, I’ve decided to work with leaflet.js, and have the POIs in a GeoJSON data layer on top of OSM. Still, I need a tool that will allow me to copy a node’s coordinates to my clipboard inside JOSM, so that I can use these coordinates in my GeoJSON file. Basically, I am using JOSM to put the floorplans as a piclayer over the OSM layer, to figure out each room’s or area’s approximate boundaries as I draw them. Because GPS signal inside buildings often fails me, this seems to be the best way for now.
Eventually, I want to work on an offline mode for the app I’m building, and have QR codes or NFC tags in particular spots inside buildings, with coordinates written on them, to locate and guide users inside buildings, even without Internet or GPS signal.
Any advice is greatly appreciated. I will have the work in progress available online very soon.
Edited: I particularly need a way to easily copy the coordinates of a node I have placed onto a JOSM layer. I really need this, but have yet to find a plugin that does it.
