[mkgmap-dev] "No roads near target" bug in Schwabmünchen

Tue Mar 19 07:59:30 GMT 2013

Hi Gerd,

I'm using berndw's excelent pygmap3.py script and his aio-basemap style
for the build.
Both are available on github
Style:
url = git://github.com/berndw1960/aiostyles

Script:
url = git://github.com/berndw1960/creategmap

my map.conf :
#######################################################
## MKGMAP basemap

link-pois-to-ways
preserve-element-order

building a "bayern"-map, the script launches mkgmap as follows:
