GeoJSONVectorSource#
- class GeoJSONVectorSource[source]#
Bases:
VectorSource
A
VectorSource
for reading GeoJSON files.Attributes
- __init__(uris: str | list[str], crs_transformer: CRSTransformer, vector_transformers: list['VectorTransformer'] = [], bbox: rastervision.core.box.Box | None = None)[source]#
Constructor.
- Parameters:
crs_transformer (CRSTransformer) – A
CRSTransformer
to convert between map and pixel coords. Normally this is obtained from aRasterSource
.vector_transformers (list['VectorTransformer']) –
VectorTransformers
for transforming geometries. Defaults to[]
.bbox (rastervision.core.box.Box | None) – User-specified crop of the extent. If
None
, the full extent available in the source file is used.
Methods
__init__
(uris, crs_transformer[, ...])Constructor.
get_dataframe
([window, to_map_coords])Return geometries as a
GeoDataFrame
.get_geojson
([window, to_map_coords])Return transformed GeoJSON.
get_geoms
([window, to_map_coords])Returns all geometries in the transformed GeoJSON as Shapely geoms.

- Parameters:
crs_transformer (CRSTransformer) – A
CRSTransformer
to convert between map and pixel coords. Normally this is obtained from aRasterSource
.vector_transformers (list['VectorTransformer']) –

- get_dataframe(window: rastervision.core.box.Box | None = None, to_map_coords: bool = False) GeoDataFrame #
Return geometries as a
GeoDataFrame
.- Parameters:
- Return type:
- get_geojson(window: rastervision.core.box.Box | None = None, to_map_coords: bool = False) dict #
Return transformed GeoJSON.
This makes the following transformations to the raw geojson:
converts to pixels coords (by default)
removes empty features
splits apart multi-geoms and geom collections into single geometries
buffers lines and points into Polygons
Additionally, the transformations specified by all the VectorTransformers in vector_transformers are also applied.
- get_geoms(window: rastervision.core.box.Box | None = None, to_map_coords: bool = False) list['BaseGeometry'] #
Returns all geometries in the transformed GeoJSON as Shapely geoms.
- Parameters:
to_map_coords (bool) – If true, will return geoms in map coordinates.
window (rastervision.core.box.Box | None) –
- Returns:
List of Shapely geoms.
- Return type:
list[‘BaseGeometry’]
