Digitizing floor plans for use in Qlik GeoAnalytics (QGA)
Update, the example app now have the drawing as a background.
Floor plans and cad drawings can be useful, for instance in production dashboards, to visualize status and flows in a factory. However cad drawings are in many cases a mess to work with.
Here's a simple, pragmatic approach to digitize rather than import the actual drawing. The major issue with most CAD drawings is lack of structure, details without meaning and the objects on the right level are missing. It’s not the format or alignment that is the problem. In many cases it's better to use the drawing as a input to produce the polygons and information needed.
In this tutorial I use QGIS for digitizing and out put to a format that is easy to import to QGA. In this example the drawing is digitized in a local reference system, ie no alignment is made with the rest of the world.
Install QGA basic, Plus not needed if Dropbox et al is used.
