Query the GLASS product registry

Source: R/glass_registry.R
glass_registry.Rd

glass_registry() returns the bundled glass_products registry, optionally filtered. glass_product_info() returns one or a few rows and errors loudly when the lookup is ambiguous, so it is handy for interactive use.

Usage

glass_registry(product = NULL, variant_id = NULL, verified_only = FALSE)

glass_product_info(variant_id = NULL, product = NULL)

Arguments

product

Product directory name(s) under /archive/, e.g. "LAI". In glass_registry(), NULL keeps all products.

variant_id

Optional exact variant key(s), e.g. "LAI_MODIS_250M".

verified_only

If TRUE, return only variants whose file naming and band metadata were verified against a sample granule.

Value

A tibble of registry rows (see glass_products for columns).
