Hello everyone, part of my PhD is to automatically model indoor environments from photographed evacuation plans. While there is still some way to go until this will be possible, I thought about suggesting this method to the OSM community as a fast and easy way of collecting data about indoors.
The idea is: 1) the user takes an image of an evacuation plan like they can be found in all public buildings, 2) warps this image using the building ground plan already available in OSM (using e.g. warper.geothings.net) 3) draws the indoor routes using JOSM and the warped image as a layer like Bing or Yahoo aerial images using the tags suggested at http://wiki.openstreetmap.org/wiki/Indoor However, http://wiki.openstreetmap.org/wiki/Beginners_Guide_1.1 states, that "As a rule of thumb, use no external resources except those available in the editors", so this is why I am writing.. What do you think of this data source? Is it usable? Is it only usable, when there is no copyright sign written on the plan? Looking forward to your thoughts about that!
