Summary

Process OSM data with python 3. This project is mainly motivated by openstreetmap.

Dependencies

Install

You can install osmRoad via pip.

pip install osmRoad

Usage

from osm import parser
from osm import road

parser

  • load_parse_osm: return bounds, nodes, ways
  • load_parse_osmxy: different from above, return nodes with coodinates

road

  • extract_connectivity: return the adjecent matrix lil_matrix (without weights)
  • extract_adj: return the adjecent list (without weights)
  • extract_edges: return the edges (without weights)
  • build_graph: return a graph in networkx (with weights)

Example

parsed_osm = parser.load_parse_osmxy(r"osm/Beijing.osm")
r = road.build_graph(parsed_osm)
print(nx.dijkstra_path(r, 296314321, 296314277))

parsed_osm = parser.load_parse_osm(r"osm/Beijing.osm")
m = road.extract_adj(parsed_osm)
