Hi Henning, okay, this is what happens: 1) You use the options add-pois-to-areas and precomp-sea 2) You have the line natural=sea & mkgmap:line2poi!=true [0x1e04 level 7] in your points file, level 7 is mapped to resolution 14. I guess you want to process nodes like this: http://www.openstreetmap.org/browse/node/305639193 3) The SeeGenerator creates polygons which overlap the tile boundary (the polygon has no name) and have the tag natural=sea (no other tag) 4) For each generated polygon the POIGenerator creates a POI, the position is calculated using method Way.getCofG(). This method calculates the average latitude and longitude values of all points of the way. The result is a point that may be located inside, but very close to the tile boundary, and it has no label. I am not sure if it makes sense to create a POI without a label? I guess yes (e.g. for bollards), so I suggest to add a check in the style. 5) When the img file is written, the coordinates are rounded to resolution 14. The rounded values may be outside of the tile boundary. @Steve: I guess we should catch this case and omit the point, or should we move the value so that the point lies inside the boundary? This can also happen with points of lines, I did not yet check what MapSource is doing with such a line. 6)When the overview is created, the rounded values are read and added to a new map that also has the tile boundary. At this stage, a check produces the error message and the point is dropped. With r2738 I've added a check so that these points are filtered before. Gerd Henning Scholland wrote
Hi Gerd, thanks for your answer.

Hi Henning, I still have this on my todo list. The messages seem to occur when creating the overview map. Maybe it is an error in mkgmap. Will I be able to reproduce the problem with the files from https://github.com/aighes/RadReiseKarte ?
Yes, you should reproduce this with using this.
Henning
