Generate a static STAC catalog from COGs — cd_stac

Scans a directory for Cloud-Optimized GeoTIFFs and builds a STAC catalog JSON file. Each COG becomes one item with cd:variable and cd:period properties parsed from the filename. The resulting catalog is compatible with cd_catalog().

Usage

cd_stac_catalog(
  cog_dir,
  output_path = "catalog.json",
  catalog_id = "era5-land",
  title = "ERA5-Land Climate Data",
  description = NULL,
  base_url = "https://stac-era5-land.s3.us-west-2.amazonaws.com"
)

Arguments

cog_dir: Character. Directory containing COG files (.tif).
output_path: Character. Path to write the catalog JSON. Default "catalog.json".
catalog_id: Character. STAC catalog ID. Default "era5-land".
title: Character. Human-readable catalog title.
description: Character. Optional catalog description.
base_url: Character. Base URL where COGs will be served. Asset hrefs are built as {base_url}/{filename}.

Value

The output path (invisibly).

Examples

if (FALSE) { # \dontrun{
cd_stac_catalog(
  "data/cogs",
  output_path = "data/catalog.json",
  base_url = "https://stac-era5-land.s3.us-west-2.amazonaws.com"
)
} # }
