Struct osmgraphing::Parser

pub struct Parser;

The parser parsing *.osm.pbf- and *.fmi-files into a graphbuilder or a graph.

The filter-pipeline

1. Download raw osm-data (see README)
2. Read in this data
3. Filter and process osm-components like nodes and edges, e.g. filtering via tags
4. Create a memory- and runtime-efficient routing-graph.

Nodes

• Coordinates: Nodes have coordinates given in (latitude, longitude).
• Height: Nodes have a height, which is ignored right now.

Edges

Every edge will have a street-type with respective default speed-limit. These defaults depend on the street-network and can be found in the respective module network.

Additional information

This pbf-parser uses osmpbfreader-rs. An own implementation would need the pbf-impl of rust, but the previously mentioned osmpbfreader works well. *.osm-xml-files are not supported, but could be read with quick-xml.

Other libraries processing openstreetmap-data can be found in the osm-wiki.
