layer_name¶

Name of the WCS layer that should be fetched from the server

Type: str

source¶

URL of the WCS server endpoint

Type: str

version¶

Default is 1.0.0. WCS version string.

Type: str

wcs_coordinates¶

The coordinates of the WCS source

Type: Coordinates

Members

__init__(**kwargs)¶: Do not overwrite me

property base_ref¶

Summary

Returns: Description
Return type: TYPE

crs: A trait for unicode strings.

property get_capabilities_url¶

Constructs the url that requests the WCS capabilities

Returns: The url that requests the WCS capabilities
Return type: str

get_data(coordinates, coordinates_index)[source]¶

{get_data}

Raises: Exception – Raises this if there is a network error or required dependencies are not installed.

get_wcs_coordinates¶

layer_name: A trait for unicode strings.

property native_coordinates¶

The coordinates of the data source.

Returns: The coordinates of the data source.
Return type: Coordinates

Notes

This is a little tricky and doesn’t fit into the usual PODPAC method, as the service is actually doing the data wrangling for us…

source: A trait for unicode strings.

version: A trait for unicode strings.

wcs_coordinates

A trait whose value must be an instance of a specified class.

The value can also be an instance of a subclass of the specified class.

Subclasses can declare default classes by overriding the klass attribute
