class documentation

class GeoTIFFDatasetImporter(foud.LabeledImageDatasetImporter, foud.ImportPathsMixin): (source)

Constructor: GeoTIFFDatasetImporter(dataset_dir, image_path, recursive, compute_metadata, ...)

Importer for a directory of GeoTIFF images with geolocation data.

See :ref:`this page <GeoTIFFDataset-import>` for format details.

Parameters
dataset_dir	the dataset directory. If omitted, `image_path` must be provided
image_path	an optional parameter that enables explicit control over the location of the GeoTIFF images. Can be any of the following: a list of paths to GeoTIFF images. In this case, `dataset_dir` has no effect a glob pattern like `"*.tif"` specifying the location of the images in `dataset_dir` an absolute glob pattern of GeoTIFF images. In this case, `dataset_dir` has no effect
recursive	whether to recursively traverse subdirectories. Not applicable when `image_path` is provided
compute_metadata	whether to produce `fiftyone.core.metadata.ImageMetadata` instances for each image when importing
shuffle	whether to randomly shuffle the order in which the samples are imported
seed	a random seed to use when shuffling
max_samples	a maximum number of samples to import. By default, all samples are imported

Method	`__init__`	Undocumented
Method	`__iter__`	Undocumented
Method	`__len__`	The total number of samples that will be imported.
Method	`__next__`	Returns information about the next sample in the dataset.
Method	`setup`	Performs any necessary setup before importing the first sample in the dataset.
Instance Variable	`compute_metadata`	Undocumented
Instance Variable	`image_path`	Undocumented
Instance Variable	`recursive`	Undocumented
Property	`has_dataset_info`	Whether this importer produces a dataset info dictionary.
Property	`has_image_metadata`	Whether this importer produces `fiftyone.core.metadata.ImageMetadata` instances for each image.
Property	`label_cls`	The `fiftyone.core.labels.Label` class(es) returned by this importer.
Instance Variable	`_filepaths`	Undocumented
Instance Variable	`_iter_filepaths`	Undocumented
Instance Variable	`_num_samples`	Undocumented

Inherited from DatasetImporter (via LabeledImageDatasetImporter):

Method	`__enter__`	Undocumented
Method	`__exit__`	Undocumented
Method	`close`	Performs any necessary actions after the last sample has been imported.
Method	`get_dataset_info`	Returns the dataset info for the dataset.
Method	`_preprocess_list`	Internal utility that preprocesses the given list---which is presumed to be a list defining the samples that should be imported---by applying the values of the `shuffle`, `seed`, and `max_samples` parameters of the importer.

Inherited from ImportPathsMixin (via LabeledImageDatasetImporter, DatasetImporter):

Static Method	`_load_data_map`	Helper function that parses either a data directory or a data manifest file into a UUID -> filepath map.
Static Method	`_parse_data_path`	Helper function that computes default values for the `data_path` parameter supported by many importers.
Static Method	`_parse_labels_path`	Helper function that computes default values for the `labels_path` parameter supported by many importers.

def __init__(self, dataset_dir=None, image_path=None, recursive=True, compute_metadata=False, shuffle=False, seed=None, max_samples=None): (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.__init__

Undocumented

def __iter__(self): (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.__iter__

Undocumented

def __len__(self): (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.__len__

The total number of samples that will be imported.

Raises
`TypeError`	if the total number is not known

def __next__(self): (source) ¶

overrides fiftyone.utils.data.importers.LabeledImageDatasetImporter.__next__

Returns information about the next sample in the dataset.

Returns
an`(image_path, image_metadata, label)` tuple , `where`	`image_path`: the path to the image on disk `image_metadata`: an `fiftyone.core.metadata.ImageMetadata` instances for the image, or `None` if `has_image_metadata` is `False` `label`: an instance of `label_cls`, or a dictionary mapping field names to `fiftyone.core.labels.Label` instances, or `None` if the sample is unlabeled
Raises
`StopIteration`	if there are no more samples to import

def setup(self): (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.setup

Performs any necessary setup before importing the first sample in the dataset.

This method is called when the importer's context manager interface is entered, DatasetImporter.__enter__.

@property
has_dataset_info = (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.has_dataset_info

Whether this importer produces a dataset info dictionary.

@property
has_image_metadata = (source) ¶

overrides fiftyone.utils.data.importers.LabeledImageDatasetImporter.has_image_metadata

Whether this importer produces fiftyone.core.metadata.ImageMetadata instances for each image.

@property
label_cls = (source) ¶

overrides fiftyone.utils.data.importers.LabeledImageDatasetImporter.label_cls

The fiftyone.core.labels.Label class(es) returned by this importer.

This can be any of the following:

a fiftyone.core.labels.Label class. In this case, the importer is guaranteed to return labels of this type
a list or tuple of fiftyone.core.labels.Label classes. In this case, the importer can produce a single label field of any of these types
a dict mapping keys to fiftyone.core.labels.Label classes. In this case, the importer will return label dictionaries with keys and value-types specified by this dictionary. Not all keys need be present in the imported labels
None. In this case, the importer makes no guarantees about the labels that it may return
