Index the AlphaEarth tile catalogue locally

Downloads the AlphaEarth Foundations spatial index and loads it into a persistent local DuckDB database so that search() runs quickly and smooth. The download and load happen once. Later calls reuse the cached database unless overwrite = TRUE.

Usage

index(overwrite = FALSE)

Arguments

overwrite

Logical. Re-download the index and rebuild the database even when a cached copy already exists.

Value

fs::path() with the path to the local database.

Details

The database and the downloaded index live under tools::R_user_dir("alphaearth", "cache").

Examples

if (FALSE) { # \dontrun{
  alphaearth::index()
} # }
