[mkgmap-dev] [locator] Separate boundary files

Thu Apr 28 20:49:51 BST 2011

Carlos,

thanks for your reports. I cannot check your examples in detail now but 
I can give you some general hints.

The current locator branch relies on complete boundaries. The word 
complete is important. The boundary precompilation algorithm does not 
automatically close multipolygons which are open and which has a loose 
endpoints out of the tile borders. This is necessary because one major 
reason for using precompiled data is that I want to get rid of wrong 
autoclosed boundaries. (Please read 
http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q1/010797.html where I 
tried to explain the problem more in detail).
If you use a dump of spain only you might loose some of the boundaries 
that are located on the border. I would recommend to download a larger 
dump and cut out a larger area than spain for boundary precompilation 
(e.g. spain + 10km around).

Of course the changes are not tested very well and there are tons of 
bugs in it. I'll have to implement some checks to see if the 
precompilation really works well.
