Convert OpenStreetMap (OSM) data to Turtle (TTL). osm2rdf converts various formats using Libosmium into valid rdf files.
Some features require boost version 1.78 or newer. To enable these features boost has to be updated manually on most systems as distributions do ship older versions.
The provided Makefile contains targets which build a Docker image, prepare input and output directories and downloads data.
To run osm2rdf on germany it is enough to call:
make docker-de
This creates the directories input, output, and scratch, downloads the data and runs osm2rdf with default parameters.
Alternatively use the provided Dockerfile to compile and run osm2rdf:
$ mkdir input
$ mkdir output
$ mkdir scratch
$ docker build -t osm2rdf .
$ wget -O ./input/germany-latest.osm.pbf https://download.geofabrik.de/europe/germany-latest.osm.pbf
$ docker run --rm -v `pwd`/input/:/input/ -v `pwd`/output/:/output/ -v `pwd`/scratch/:/scratch/ -it osm2rdf /input/germany-latest.osm.pbf -o /output/germany-latest.osm.ttl -t /scratch/
On Ubuntu 20.04 the following packages are required to build osm2rdf:
clang clang-tidy g++ libboost-dev libboost-serialization-dev libexpat1-dev cmake libbz2-dev zlib1g-dev libomp-dev
clang is optional, but without it clang-tidy has unrelated error messages.
Clone and build osm2rdf:
$ git clone https://github.com/ad-freiburg/osm2rdf.git
$ cd osm2rdf
$ mkdir -p build && cd build && cmake -DCMAKE_BUILD_TYPE=Debug .. && make -j4 && cd ..
Prepare input, output and scratch folders and download some data and convert the data to ttl:
$ mkdir input
$ mkdir output
$ mkdir scratch
$ wget -O ./input/freiburg-regbez-latest.osm.pbf https://download.geofabrik.de/europe/germany/baden-wuerttemberg/freiburg-regbez-latest.osm.pbf
$ ./build/osm2rdf ./input/freiburg-regbez-latest.osm.pbf -o ./output/freiburg-regbez-latest.osm.ttl
