I'm looking for ways to convert a raster image of a floor plan to workable data in a sense that the program should be able to locate the destination by referring to the co-ordinates of matching "ID/name" on the map. I have searched for more information in regards to the topic and have found many types of plug-ins such as openstreetmap and qgis but am unsure how to go about with the shapefiles. Now, I am wondering if there was another way instead of using plug-ins or am I just shooting myself in the foot ? My idea of rendering the map:

- use region-growing from the words to detect the "area" that the word is contained in
- Store the coordinates of the corner points detected in the area
