Download OSM data

Download OpenStreetMap data

You can use the following two methods to download the OpenStreetMap data:

1. OpenStreetMapOfficial: choose Export -> OverpassAPI (otherwise the size of the bounding box size is limited).

OpenStreetMap Official

By this way, you will get the complete OSM data (xml), then you can use osm_filter.osm_way_filter() to get the layer you need.

2. Overpass API (recommended): directly use overpass API to download the layer you need. The sample query code is attached in the appendix Appendix A: Query code.

Overpass API

In this way, you will directly get the layer you need.

Parse OpenStreetMap data

The downloaded OpenStreetMap xml file can be parsed using the mtldp.mtlmap.build_network_from_xml():

import mtldp.mtlmap as mtlmap
network = mtlmap.build_network_from_xml("*.osm")

This will return you a well-structured class mtldp.mtlmap.Network.

Appendix A: Query code

Here is an example of the query code using the OverpassAPI.
