Data source name for a named spatial data source

Look up a source by name in the sds registry and return a GDAL-ready data source name (DSN). The registry records the kind of every source, so the returned string is fully dressed: '/vsicurl/' for online rasters and Parquet, '/vsizip//vsicurl/' for zipped vector sources, complete 'WMTS:' connection strings for tile services, and full XML or VRT text for sources that are recipes rather than URLs.

Usage

dsn(name)

Arguments

name

character vector of registry names, see dsn_list()

Value

character vector of GDAL data source names, same length as 'name'

Details

There is deliberately no prefix toggle. If you want the bare URL, take it from the 'url' column of dsn_list(), or unchain with dsn::unvsicurl(). To chain further, compose with dsn verbs or the 'vrt://' protocol, for example 'paste0("vrt://", dsn("esri_world_imagery"), "?ovr=12")'.
