1.3. Demos: Postprocessing, adcp_database_maker.py, and commandline

The post-processing tutorial demonstrates typical steps to take with a UHDAS dataset acquired at sea.

The two datasets we will process, UHDAS and VmDAS data, will be demonstrated using adcp_database_maker.py. Additional demos will show how to obtain the same data results using command-line steps.

The processing examples below use the data from the adcp_py3demos*.zip files mentioned in the CODAS Installation instructions. Paths given below match the virtual computer, for simplicity. For example, on the virtual machine:

• the adcp_py3demos source is in: /home/adcpcode/programs/adcp_py3demos

• the examples use ~/my_adcp_py3demos to do the demos.

Instructions for each processing example exist in four places:

• using adcp_database_maker.py: these adcp_py3demos tutorials

• basic instructions: quick_adcp.py command-line help

• annotated instructions: see links in each section

• with metadata: the text files associated with the processing (in the adcp_py3demos/adcp_pyproc directories) have the same (basic) instructions, with additional meta-data included. These completed files are a good example of what to submit with your data when you send it in to the Joint Archive for Shipboard ADCP, JASADCP

Note

You really need to do the postprocessing demo first. Then Then it’s relatively easy to go through the steps necessary for your scenario using adcp_database_maker.py. If for some reason that doesn’t work, the last set of demos shows you the actual steps going on behind the scenes, in case you need to do things more manually. This table has a little more detail about the manual commands used in the processing.
