Rework of the POI searchability – November 2011

Over the last few weeks I spent a lot of time (about 130 hours total) on reworking the whole Points of Interest (POI — all points in the map) framework. I did this because I noticed that some points were not found on the newer garmin devices like before.

For some it might be known, but most will not know that Garmin uses a rather complicated system to determine what point can be found at which place on the GPS/Mapsource and also determine the maximum resolution at which it is shown. This system is based on a rather random system of FFFFF points. Only a few of those are however usable and searchable. Hence it took me a long time to tryout to analyse and tryout about 2000 (hex) of them to find out which ones have which properties.
