A hand-written streaming byte parser for OpenStreetMap Protobuf data.

streaming-osm

This library provides the ability to read and process OpenStreetMap data via the streaming ecosystem. Since streaming allows for very little RAM overhead despite file size, we can process very large OSM PBF files just by providing a file path:

import           Streaming
import           Streaming.Osm
import qualified Streaming.Prelude as S

-- | Count all nodes.
count :: IO ()
count = do
  len <- runResourceT . S.length_ . nodes . blocks $ blobs "yourfile.osm.pbf"
  print len
