[mkgmap-dev] [PATCH v1] LocationHook speedup

From WanMil wmgcnfg at web.de on Thu Dec 29 14:11:35 GMT 2011

Gerds patches inspired me to look for more things that could be improved.

I found that the Quadtree used in the LocationHook is not very optimal.
The patch is a first try to increase the performance. The time required 
for the LocationHook is reduced by 10-50% which is great.

Warning: I haven't checked so far if the results are equal. So maybe 
there are big bugs in the patch...  (and the speedup comes from the poor 

I will do some more tests and optimizations but maybe some of you can 
have a look on it, test it and comment it.

Have fun!
