This guide describes how to convert an arbitrary image to a clickable map. I use it for drawings and sketches, for floor plans I often use another approach, see this article.
Here's the high level workflow, using Qlik Sense, Qlik GeoAnalytics and open source tools:
- Find a suitable image, the hardest part by far.
- Bucket fill areas, I prefer Inkscape.
- Vectorize and Simplify, QGIS is useful.
- Load into Sense.
- Done!
See below attachments for a step by step guide and some example files. The final result can be used in the native Sense map chart as well as in the map of Qlik GeoAnalytics for Sense and QlikView.
