'Visualization for Indoor Positioning System in Real Time
I want to visualize moving assets on a indoor map of a facility. I think the first step would be to trace floor plan image in some form of accurate vector drawing with precise lengths of all the structures to create a digitized version of the facility.
The hardware setup gives me relative x,y positioning, for example within 50x50 meters bounding box where coordinates are 0,0 (left bottom point) to 50,50 (right top).
Accuracy of the indoor map drawing is very critical for the application as I need to plot moving objects. I came across OpenStreetMap's indoor maps libraries like openindoor6, it looks good for static maps to show internal structures of the buildings, but I've doubts about the measurement accuracy of the structures (length of walls, room sizes, etc) as I'll have to manually Georeference the floorplan, then map the x, y coordinates that I obtain from the hardware to LatLon.
In short, I need tools that'll help me to draw accurate indoor maps with reliable coordinate system, do some layering stuff like using markers, marking zones and indoor geofencing.
I'm looking for open source tools if possible to achieve all this. Any suggestions? TIA.
