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:
1 2 | >>> 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:
1 2 | >>> 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:
1 2 | >>> city.fid0 |
-
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:
1 2 | >>> 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:
1 2 | >>> city.index('Population')1 |
