z Returns a list of Z coordinates in this line, or None if the line does not have Z coordinates: >>> OGRGeometry('LINESTRING (1 2 3,4 5 6)').z [3.0, 6.0]

y Returns a list of Y coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').y [2.0, 4.0]

x Returns a list of X coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').x [1.0, 3.0]

class LineString x Returns a list of X coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').x [1.0, 3.0] y Returns a list of Y coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').y [2.0, 4.0] z Returns a list of Z coordinates in this line, or None if the line does not have Z coordinates: >>> OGRGeometry('LINESTRING (1 2 3,4 5 6)').z [3.0, 6.0]

test_capability(capability) Returns a boolean indicating whether this layer supports the given capability (a string). Examples of valid capability strings include: 'RandomRead', 'SequentialWrite', 'RandomWrite', 'FastSpatialFilter', 'FastFeatureCount', 'FastGetExtent', 'CreateField', 'Transactions', 'DeleteFeature', and 'FastSetNextByIndex'.

srs Property that returns the SpatialReference associated with this layer: >>> print(layer.srs) GEOGCS["GCS_WGS_1984", DATUM["WGS_1984", SPHEROID["WGS_1984",6378137,298.257223563]], PRIMEM["Greenwich",0], UNIT["Degree",0.017453292519943295]] If the Layer has no spatial reference information associated with it, None is returned.

spatial_filter Property that may be used to retrieve or set a spatial filter for this layer. A spatial filter can only be set with an OGRGeometry instance, a 4-tuple extent, or None. When set with something other than None, only features that intersect the filter will be returned when iterating over the layer: >>> print(layer.spatial_filter) None >>> print(len(layer)) 3 >>> [feat.get('Name') for feat in layer] ['Pueblo', 'Lawrence', 'Houston'] >>> ks_exten

num_fields Returns the number of fields in the layer, i.e the number of fields of data associated with each feature in the layer: >>> layer.num_fields 4

num_feat Returns the number of features in the layer. Same as len(layer): >>> layer.num_feat 3

name Returns the name of this layer in the data source. >>> layer.name 'cities'
