R Interface to DuckDB Database with Spatial Extension
Fast and memory-efficient functions to analyze and manipulate large spatial datasets. It leverages the fast analytical capabilities of ‘DuckDB’ and its spatial extension (see ) while maintaining compatibility with R’s spatial data ecosystem to work with spatial vector data.
Primitives to Generate Static SpatioTemporal Asset Catalogs
Provides reusable primitives to build and serialize static SpatioTemporal Asset Catalog (STAC) documents, including catalogs, collections, items, assets, and links. The package implements the STAC specification version 1.0.0 () and is intended as a foundation for other tools, such as STAC generators and experiment catalog builders. Optional spatial metadata extraction and thumbnail rendering are supported through terra, and QGIS style parsing through xml2, when these packages are available.
