As an example we'd like to render tiles for tile level 13, 15 and 17 of San Francisco. First you need the osm.pbf file for that region. In our case we get it from:
where we locate the link to the pbf file as http://download.geofabrik.de/north-america/us/california-latest.osm.pbf
Now we need the tools for conversion and filtering the pbf file into tiles. In order to compile the tools you should have zlib installed on your system (e.g. via sudo apt-get install zlib1g-dev). Then run:
cd /tmp wget http://m.m.i24.cc/osmconvert.c gcc -O3 -o osmconvert osmconvert.c -lz sudo mv osmconvert /usr/local/bin
if that works, running
should output usage instructions.
Please compile Marble from source code as well as described in https://marble.kde.org/sources.php and make sure to compile the development version (master branch). Pass the option -DBUILD_MARBLE_TOOLS=TRUE to cmake in order to compile all Marble tools.
Now our tool is needed. In a shell, go to the marble build directory and then
should give usage instructions.
The tile cutter tool works as follows: You call it with a link to an osm .pbf file as parameter.
The tool will generate tiles for zoom levels 11, 13, 15 and 17 by default. You can overwrite that using the -z switch, e.g. -z 13 15.
If you follow the steps above, the final tile creation run after installing the required tools will look like this:
cd ~/marble/build/ cd tools/vectorosm-tilecreator ./marble-vectorosm-tilecreator http://download.geofabrik.de/north-america/us/california-latest.osm.pbf [========================================>] 100% 734.4/734.4 MB Downloading california-latest.osm.pbf [========================================>] 100% 0.0/0.0 MB Downloading california.poly [========================================>] 100% osm cache tiles complete. [========================================>] 100% landmass cache tiles complete. [========================================>] 100% Vector OSM tiles complete.
For large countries the tile creation can take several hours or even days. If you're just interested in a certain region (say, a city), you can preprocess the pbf and extract the region you're interested in. Use osmconvert for that like this:
osmconvert --complex-ways --complete-ways -b=8.3735,49.0016,8.4409,49.0261 -o=smallregion.pbf largeregion.pbf ./marble-vectorosm-tilecreator smallregion.pbf
The four numbers of the bounding box passed with the -b=... parameter can be obtained from the OSM export tool in the order left, bottom, right, top.
