SubdatasetInfo

Parses a subdataset path for container formats that hold multiple datasets (NetCDF, HDF5, …), where a path looks like NETCDF:"file.nc":variable. Obtain one from Gdal.getSubdatasetInfo(path) (or new SubdatasetInfo(path)).

Usage

parse a subdataset path

const si = await Gdal.getSubdatasetInfo('NETCDF:"/opfs/climate.nc":tas');
console.log(await si.getPathComponent());        // /opfs/climate.nc
console.log(await si.getSubdatasetComponent());  // tas

Methods

METHOD	DESCRIPTION
`getPathComponent()` → `string`	The file-path part of the subdataset path.
`getSubdatasetComponent()` → `string`	The subdataset (variable) part.
`modifyPathComponent(newPath)` → `string`	Swap the file path, keeping the subdataset selector, useful to repoint a subdataset reference at a moved file.
