osm_cartography.geo_map

Class for manipulating GeographicMap data.

Warning

This module is unstable and still evolving. It will probably end up residing in some other package.

class osm_cartography.geo_map.GeoMap(gmap)

GeoMap provides an internal geographic_msgs/GeographicMap representation.

Parameters:gmap – geographic_msgs/GeographicMap message.

bounds()

Returns:geographic_msgs/BoundingBox from the geographic_msgs/GeographicMap message.

header()

Returns:std_msgs/Header from the geographic_msgs/GeographicMap message.

class osm_cartography.geo_map.GeoMapFeatures(geomap)

GeoMapFeatures provides a filtering iterator for the features in a osm_cartography.geo_map.GeoMap.

Parameters:geomap – GeoMap object.

GeoMapFeatures provides these standard container operations:

len(features)

Returns:The number of points in the set.

features[uuid]

Returns:The point with key uuid. Raises a KeyError if uuid is not in the set.

uuid in features

Returns:True if features has a key uuid, else False.

uuid not in features

Equivalent to not uuid in features.

iter(features)

Returns:An iterator over all the features. This is a shortcut for iterkeys().

Example:

gm = GeoMap(msg)
gf = GeoMapFeatures(gm)
for feat in gf:
    print str(feat)

next()

Next matching feature.

Returns:geodesy.wu_point.WuPoint object for next point Raises:StopIteration when finished.
