There is no one-size-fits-all packaging for data, as the optimal packaging is highly use-case dependent.
Authors: Chris Durbin, Patrick Quinn, Dana Shum
File formats are read-oriented to support:
|Format||Data Type||Standard Status|
|Cloud-Optimized GeoTIFF (COG)||Raster||OGC standard for comment|
|Zarr, Kerchunk||Multi-dimensional raster||ESDIS and OGC standards in development|
|Cloud-Optimized Point Cloud (COPC), Entwine Point Tiles (EPT)||Point Clouds*||no known ESDIS or OGC standard|
|FlatGeobuf, GeoParquet,||Vector||no known ESDIS, draft OGC standard|
|Cloud-Optimized GeoTIFF (COG)||Widely adopted||OGC standard for comment|
|Zarr, Kerchunk||(Less) widely adopted, especially in specific communities||ESDIS and OGC standards in development|
|Entwine Point Tiles (EPT), Cloud-Optimized Point Cloud (COPC)||Less common (PDAL Supported)||no known ESDIS or OGC standard|
|GeoParquet, FlatGeobuf||Less common (OGR Supported)||no known ESDIS, draft OGC standard|
