> Hi,
> attached is a patch that implements LocationHook with a new Quadtree.
> With my test data, it makes mkgmap about 10% faster.
> Remarks:
> - Some Nodes and ways are not found. I think that's because they lie exactly
> on boundaries. The same problem occurs with mkgmap from trunk. As a work
> around I suggest to search those nodes again with coords decreased by 1.
> - More time may be saved if we manage to save the preprocessed boundary data
> in a format that can be directly loaded into the quadtree.
