osm2geojson

Converts Open Street Map osm files into geojson, or optionally “one feature per line” format

Works on osm files or streams, allowing it to process files directly from the network, without downloading them first.

To do

Note osm2geojson currently extracts only points. More complicated structures are not implemented yet.

To install

go get github.com/donomii/osm2geojson
go install github.com/donomii/osm2geojson

To use

As a stream processor

cat europe.osm | ./osm2geojson

type europe.osm | osm2geojson

Converting directly from the internet

wget -q -O - http://download.geofabrik.de/antarctica-latest.osm.bz2 | bunzip2  | ./osm2geojson

or you can use the --compression flag to use the internal decompressor

wget -q -O - http://download.geofabrik.de/antarctica-latest.osm.bz2 |  ./osm2geojson --compression bz2

Read from file, write to stdout

./osm2geojson europe.osm.bz2

osm2geojson europe.osm.bz2 

Read from file, write to file

./osm2geojson europe.osm.bz2 europe.geojson.gz

osm2geojson europe.osm.bz2 europe.geojson.gz

Read from stdin, write to file

./osm2geojson - europe.geojson.gz

osm2geojson - europe.geojson.gz

Correct geojson format

By default, osm2geojson prints each feature on a new line, so you can use command line tools like GREP and AWK to filter the results. e.g. to get every mountain in Europe:

./osm2geojson europe.osm.bz2 | grep -i mountain

However this is not correct geojson. To get correct geojson, add --strict to your command.

./osm2geojson --strict europe.osm.bz2

Note that correct geojson is all on one line, so you can no longer use command line tools.
