ObjectDetectionGeoJSONStore

class ObjectDetectionGeoJSONStore

Bases: LabelStore

Storage for object detection predictions.

Attributes

bbox
crs_transformer

__init__(uri: str, class_config: ClassConfig, crs_transformer: CRSTransformer, bbox: Optional[Box] = None)

Constructor.

Parameters

• uri (str) – uri of GeoJSON file containing labels

• class_config (ClassConfig) – ClassConfig used to infer class_ids from class_name (or label) field

• crs_transformer (CRSTransformer) – CRSTransformer to convert from map coords in label in GeoJSON file to pixel coords.

• bbox (Optional[Box], optional) – User-specified crop of the extent. If provided, only labels falling inside it are returned by ObjectDetectionGeoJSONStore.get_labels().

Methods

__init__(uri, class_config, crs_transformer)	Constructor.
get_labels()	Loads Labels from this label store.
save(labels)	Save labels to URI.
set_bbox(bbox)	Set self.extent to the given value.

__init__(uri: str, class_config: ClassConfig, crs_transformer: CRSTransformer, bbox: Optional[Box] = None)

Parameters

• uri (str) – uri of GeoJSON file containing labels

• class_config (ClassConfig) – ClassConfig used to infer class_ids from class_name (or label) field

• crs_transformer (CRSTransformer) – CRSTransformer to convert from map coords in label in GeoJSON file to pixel coords.

• bbox (Optional[Box], optional) – User-specified crop of the extent. If provided, only labels falling inside it are returned by ObjectDetectionGeoJSONStore.get_labels().

get_labels() → ObjectDetectionLabels

Loads Labels from this label store.
