VectorSource#
- class VectorSource[source]#
Bases:
ABC
A source of vector data.
Attributes
- __init__(crs_transformer: CRSTransformer, vector_transformers: List[VectorTransformer] = [], bbox: Optional[Box] = 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 (Optional[Box]) – User-specified crop of the extent. If None, the full extent available in the source file is used.
Methods
__init__
(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.
- __init__(crs_transformer: CRSTransformer, vector_transformers: List[VectorTransformer] = [], bbox: Optional[Box] = 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 (Optional[Box]) – User-specified crop of the extent. If None, the full extent available in the source file is used.
- get_dataframe(window: Optional[Box] = None, to_map_coords: bool = False) geopandas.GeoDataFrame [source]#
Return geometries as a
GeoDataFrame
.- Parameters
- Return type
- get_geojson(window: Optional[Box] = None, to_map_coords: bool = False) dict [source]#
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.
