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

Tue Jan 24 16:04:47 GMT 2012

Hi Thorsten,

I can confirm this problem. I can repdroduce it with a "boundary" which
contains these 4 points:
[2412980/371559, 2412981/371558, 2412992/371544, 2412980/371559]
The Way.clockwise() method says it is counter-clockwise.
Besides rounding errors, it is a line, not a shape, and I guess that causes
the problem. The clockwise() method calculates an area size of 3, which is
almost zero.

It is quite likely that the intersection of two areas produces these "nearly
empty" (parts of) areas, what we need is a filter that throws them away. 

I am not sure if WanMil is already working on this?
