Catalog

Bases: CatalogBase, VizTools

The Catalog class enables access to the UP42 catalog functionality (data archive search & ordering).

Use catalog:

catalog = up42.initialize_catalog()

This class also inherits functions from the CatalogBase class.

Parameters:

Name	Type	Description	Default

end_date	str	Query period ending day, format "2020-01-01".	'2020-01-30'
usage_type	List[str]	Optional. Filter for imagery that can be purchased & downloaded or also processed. ["DATA"] (can only be downloaded), ["ANALYTICS"] (can be downloaded or used directly with a processing algorithm), ["DATA", "ANALYTICS"] (can be any combination). The filter is inclusive, using ["DATA"] can also result in results with ["DATA", "ANALYTICS"].	None
limit	int	The maximum number of search results to return (1-max.500).	10
max_cloudcover	Optional[int]	Optional. Maximum cloud coverage percent - e.g. 100 will return all scenes, 8.4 will return all scenes with 8.4 or less cloud coverage.	None
