netcdf_to_geocsv

Overview¶

The netcdf_to_geocsv tool is a utility tool for converting a netCDF CVM file to the corresponding CSV, GeoCSV format and optionally output its JSON metadata.

In this tutorial, we will demonstrate how to convert the Cascadia-ANT+RF-test.nc file to GeoCSV format and generate its metadata in JSON.

Steps¶

1. Navigate to the Model Directory

   Change your directory to the location of the model file:

   cd sample-files/Cascadia-ANT+RF-Delph2018

2. Run the netcdf_to_geocsv Script

   Use netcdf_to_geocsv tool to convert the Cascadia-ANT+RF-test.nc file to GeoCSV and output its metadata in JSON:

   ../../src/netcdf_to_geocsv.py -i Cascadia-ANT+RF-test.nc -c true -g true -m true

Command Breakdown

• -i Cascadia-ANT+RF-test.nc : Specifies the name of the input file to convert.

• -c true : Sets the CSV conversion flag to True.

• -g true : Sets the GeoCSV conversion flag to True.

• -m true : Sets the JSON metadata output flag to True.

Note: You may set any of the above options to false to disable that option.

Note: The output files will have the same name as the input file but with .csv and .json extensions for the model file and metadata file respectively. If both CSV and GeoCSV files are requested, the GeoCSV file’s extension will be .gcsv.

Output Files¶

By running the command, the tool will generate three files:

• Cascadia-ANT+RF-test.gcsv : The converted GeoCSV file.

• Cascadia-ANT+RF-test.csv : The converted CSV file.

• Cascadia-ANT+RF-test.json : The metadata in JSON format.
