Open converted files¶
Open a converted netCDF or Zarr dataset¶
Converted netCDF and Zarr files can be opened with the open_converted
function
that returns a lazy loaded EchoData
object (only metadata are read during opening):
import echopype as ep
nc_path = './converted_files/file.nc' # path to a converted nc file
ed = ep.open_converted(nc_path) # create an EchoData object
EchoData object¶
EchoData
is an object for conveniently handling raw converted data from either
raw instrument files (via open_raw
) or previously converted and standardized raw files
(via open_converted
). It is essentially a container for multiple xarray Dataset
objects,
where each such object corresponds to one of the netCDF4 groups specified in the SONAR-netCDF4
convention followed by echopype. It is used for conveniently accessing and exploring the
echosounder data and for calibration and other processing.
