Convert the ASEG data to netcdf

# Path to example files
data_path = '..//..//supplemental//'

# Survey Metadata file
..//supplemental = data_path + "region//MAP//data//Tempest_survey_information.json"

# Establish survey instance
survey = Survey(..//supplemental)

# Define input ASEG-format data file and associated variable mapping file
d_data = data_path + 'region//MAP//data//Tempest.dat'
d_supp = data_path + 'region//MAP//data//Tempest_data_information.json'

# Read data and format as Tabular class object
survey.add_tabular(type='aseg', data_filename=d_data, metadata_file=d_supp)

# Define input ASEG-format model file and associated variable mapping file
m_data = data_path + 'region//MAP//model//Tempest_model_0.dat'
m_supp = data_path + 'region//MAP//model//Tempest_model_information.json'

# Read model data and format as Tabular class object
survey.add_tabular(type='aseg', data_filename=m_data, metadata_file=m_supp)

# Save NetCDF file
d_out = data_path + 'region//MAP//data//Tempest.nc'
survey.write_netcdf(d_out)

Read in the netcdf files

new_survey = Survey().read_netcdf(d_out)
