dem_band_mapping: Landsat band mapping

In rsi: Efficiently Retrieve and Process Satellite Imagery

Landsat band mapping

Description

This object is structured slightly differently from other band mapping objects; it is a list of named lists, whose names correspond to DEM collections available within a given STAC catalog. Those named lists are then more standard band mapping objects, containing character vectors with names corresponding to asset names and values equal to elevation.

Usage

dem_band_mapping

Format

An object of class list of length 1.

Details

Band mapping objects:

These objects are semi-standardized sets of metadata which provide all the necessary information for downloading data from a given STAC server. The object itself is list of character vectors, whose names represent asset names on a given STAC server and whose values represent the corresponding standardized band name from the Awesome Spectral Indices project. In addition to this data, these vectors usually have some of (but not necessarily all of) the following attributes:

• stac_source: The URL for the STAC server this metadata corresponds to.

• collection_name: The default STAC collection for this data source.

• download_function: The function to be used to download assets from the STAC server.

• mask_band: The name of the asset on this server to be used for masking images.

• mask_function: The function to be used to mask images downloaded from this server.
