[mkgmap-dev] Performance of POI search on the Device

From Gerd Petermann gpetermann_muenchen at hotmail.com on Mon Jun 1 09:21:55 BST 2020

Hi Franco,

while experimenting I would simply use JOSM to do that. There is no need to create a map with many tiles, I think could reproduce the problem with a single tile.
If you find out that this helps I can add an option to mkgmap to add at least one POI in the center of the map.

Hi Gerd,
I tried to rebuild one of my layers with the options "index" and "route".
That didn't make any difference.
I have used my "housenumbers" layer, it does not contain contourlines

How can I build a map with one POI per tile?
