How does this work with base styles? I would like to include base-style=landuse (which seems stripped out of the default style?) but I get StyleImpl.java:140 errors. In the default style I see these lines in the info file: base-style=contours_ft #base-style=location base-style=waters Only if I remove those 3 lines in that info file, I can run mkgmap (r2140) without errors. I have copied all the substyle folders (like contours_ft, waters) to the same directory (styles) as the default style folder. My args file looks like this: style-file: styles\default generate-sea: multipolygon,extend-sea-sectors bounds: c:\Downloads\bounds latin1 code-page: 1252 tdbfile location-autofill: bounds,is-in,nearest name-tag-list=name,name:nl,name:fr,name:de,int_name show-profiles=1 ignore-maxspeeds remove-short-arcs merge-lines add-pois-to-areas add-pois-to-lines min-size-polygon: 4 preserve-element-order keep-going net route index nsis
