Package Summary

Geographic mapping using Open Street Map data.

Overview

This experimental package was an early rapid-prototyping test bed for the geographic_info API for Open Street Map.

It is no longer in active development, but some people have found it useful, and it still has some level of support.

Uniform Resource Locators

The location of XML map data in Open Street Map format is specified by URL. The current implementation only supports these URL types:

  • file:///full/path/to/local/map.xml

  • package://ros_package/data/map.osm

ROS Interface

osm_server node

ROS node that parses XML in Open Street Map format and returns geographic_msgs data to the caller.

Services

get_geographic_map (geographic_msgs/GetGeographicMap)
  • OSM map data from the requested URL

viz_osm node

ROS node that requests Open Street Map geographic_msgs information from the osm_server node, publishing it as rviz visualization markers.

Published Topics

visualization_marker_array (visualization_msgs/MarkerArray)
  • Markers for OSM map data from the requested URL.

Services Called

get_geographic_map (geographic_msgs/GetGeographicMap)
  • OSM map data for the requested URL.

Parameters

map_url (string)
  • Uniform Resource Locator for XML map in OSM format.

viz_osm Launch File

Runs the osm_cartography nodes, passing the URL of a local file containing the map.

Because UTM map coordinates are generally too large for the float representation used by rviz, it will probably be necessary to publish a transform to some nearby Cartesian coordinate frame within about 10 km, and use that for visualization. You can name that as you like, these examples call it map_local.

Arguments

url (string)

  • Uniform Resource Locator for XML map in OSM format.

Example

In one terminal window, create a transform from the /map frame to /local_map:

    rosrun tf static_transform_publisher 622150 3362350 0 0 0 0 1 map local_map 100

Then, launch the visualization nodes:

    roslaunch osm_cartography viz_osm.launch url:=package://osm_cartography/tests/prc.osm

Finally, run rviz, create a Marker display and set the static frame to local_map. You'll probably need to zoom out.

Map Visualization

The goal is to translate OSM data for a region into rviz markers. Currently, the viz_osm node only publishes "interesting" information, like roads and buildings. For a full implementation, that will need to be selectable.
