process osm data in python3

Summary

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

Dependencies

• scipy, numpy
• networkx

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)
