[mkgmap-dev] Problems searching for California addresses

Mon Mar 5 05:57:51 GMT 2012

Thanks to everyone for your help.

Here is what I have found with styles:
1) the "info" file included with the default style is what is causing 
the StackOverflowError.  More specifically the "base-style=" lines.  I 
am not sure from the documentation that I have found what these should be.

2) the included default style is different from the example default 
style.  I verified that the example default style was identical to the 
default style that is part of the jar file.  I can tell they are 
different because the .img files that are created are very different in 
size.  I have no idea what the differences actually are.
   47588352 bytes for --style=default
   38774784 bytes for --style-file=examples/styles/default
I tried adding the map-features.csv that is part of the jar to the 
example default style which got the size closer
   43748352 bytes for --style-file=examples/styles/default w/ 
map-features.csv
Again I have no idea what this has added, and or what difference still 
exist between it and the default style.

3) Ignoring the file size difference.  The examples/styles/default 
appears to function the same with regards to addresses as the default.  
I was able to comment out the hamlet style and it seems to have had the 
same effect as manually deleting all the hamlets.

Here are the steps that seem to result in a reasonable California map 
with address search capability:

1) Download california.osm.bz2 from cloudmade.com last updated 13 
December 2011
http://downloads.cloudmade.com/americas/northern_america/united_states/california#downloads_breadcrumbs

2) Download and unzip boundary file world_*.zip from 
http://www.navmaps.eu/wanmil/ (should automatically end up in a 
directory "bounds")

3) Use splitter version r200 to create tiled osm.pbf files
java -Xmx2000m -jar splitter.jar --mapid=63240001 california.osm.bz2

4) Edit examples/styles/default/points to remove hamlets
comment the line "place=hamlet [0x0b00 resolution 24]" in your points 
style file

5) Create Map
java -Xmx2500m -jar mkgmap.jar --route --remove-short-arcs 
--location-autofill=bounds,is_in --style-file=examples/styles/default 
--index --gmapsupp *.osm.pbf

I'm sure this isn't a perfect solution, but it give vastly superior 
results to either just using bounds (too few cities), or using is_in 
with hamlet information (too many "cities") for California.

Thanks again,
