Hi Steve, great. I did some experiments with different values for MAX_DIVISION_SIZE and found no change in the redraw time in my Oregon 450t. (no stopwatch, just the "felt time" ) Maybe my home area simply doesn't have many overlaps. So, what I am looking for is a tool that helps to find areas which are heavily overlapped, something like a heatmap. Anyway, for the beginning I should be happy with any tool that helps to find those places. Gerd

Hi Gerd
Now I wonder what threshold values to use and if there is an existing tool that allows to display the overlaps.
Any ideas?
I've used http://garmin-img.cvs.sourceforge.net/viewvc/garmin-img/ImgViewer/ in the past although not had much luck making it work today.
I have just written a program to create an svg file with the subdivisions so it can be displayed in inkscape or similar.
I'll post it tomorrow.
