[mkgmap-dev] mkgmap r2179: Still NullPointerException in BoundaryUtil

Tue Jan 24 18:03:53 GMT 2012

Hi WanMil,

I have coded a small test that tries to detect these "spike-like" areas. Idea: 
If the area size is much smaller (I used 20 as a threshold) than that of the bounding box we should remove 
the way from the area.

I am not sure regarding the threshold value, but I think the principle is ok. 
What do you think?

Gerd
