gis.gdal.Feature

class Feature

Feature wraps an OGR feature. You never create a Feature object directly. Instead, you retrieve them from a Layer object. Each feature consists of a geometry and a set of fields containing additional properties. The geometry of a field is accessible via its geom property, which returns an OGRGeometry object. A Feature behaves like a standard Python container for its fields, which it returns as Field objects: you can access a field directly by its index or name, or you can iterate over a feature’s fields, e.g. in a for loop.

geom

Returns the geometry for this feature, as an OGRGeometry object:

>>> city.geom.tuple
(-104.609252, 38.255001)

get

A method that returns the value of the given field (specified by name) for this feature, not a Field wrapper object:

>>> city.get('Population')
102121

geom_type

Returns the type of geometry for this feature, as an OGRGeomType object. This will be the same for all features in a given layer and is equivalent to the Layer.geom_type property of the Layer object the feature came from.

num_fields

Returns the number of fields of data associated with the feature. This will be the same for all features in a given layer and is equivalent to the Layer.num_fields property of the Layer object the feature came from.

fields

Returns a list of the names of the fields of data associated with the feature. This will be the same for all features in a given layer and is equivalent to the Layer.fields property of the Layer object the feature came from.

fid

Returns the feature identifier within the layer:

>>> city.fid
0

layer_name

Returns the name of the Layer that the feature came from. This will be the same for all features in a given layer:

>>> city.layer_name
'cities'

index

A method that returns the index of the given field name. This will be the same for all features in a given layer:

>>> city.index('Population')
1
