osm4scala v1.0
Few days ago, I released the first version of osm4scala. A library used
to iterate easily over Open Street Map entities stored in a osm.pbf file.
I implemented a library to iterate over all entities easily, hiding all
difficult of decoding, and with the powerful of the Scala Iterator. For
example, to generate an iterator and count all elements of type "Node",
it is so simple as:
EntityIterator.fromPbf(inputStream).count(_.osmModel == OSMTypes.Node)
Its performance surprised me.
For example, iterate over a the full planet data set with (near of 4,000
millions of elements and 39GB) stored in a external USB3 drive and using
only one thread takes only 40 minutes.
Other example is the iteration over all data of Spain: 32 seconds to
iterate over near of 70 millions of elements
