As much as possible, this FAQ answers with links to the documentation.
Different data types have support via Matlab or Python. Check this link
There are pages in the documentation describing most of the serial heading messages UHDAS acquires that have a quality indicator. Check the ` Troubleshooting ../Troubleshooting/ashtech_diagnostics.html section.
You will need several different programs, as well as software from the UH ADCP group. Installation instructions are here.
It depends on your background, but the short answer is: ‘yes, it will take some time to learn, but less time than it would take to write your own code’.
That depends on many factors, including
- how well you know your computer (the commandline interface, how to configure the paths and environment variables)
- how good your dataset is (does it have clock problems? navigation problems?)
- the manner in which the heading correction (to the gyro) will be calculated
After setting up the computer, it really depends on the data. It could be days or weeks.
This documentation is available in the file adcp_doc.zip – the link is this page
If you are about to leave, and you want to be able to run CODAS processing off line, you should plan to install and test all the necessary programs before you leave. Follow these instructions to ensure that CODAS setup and processing documentation is accessible on your computer. By far, the easiest way to do this is to
- install Virtual Box
- download the Virtual Computer, and import it.
If all you want to do is look at UHDAS data at sea, check this link to see what kinds of data are available.
That depends on the instrument and data acquisition system used on your cruise.
The database has undergone preliminary processing, but steps remain to ensure there are no calibration errors, gaps, or bad profiles.
You must have a computer with a working CODAS processing installation. Follow these instructions to ensure that CODAS processing software is set up on your computer. By far, the easiest way to do this is to choose the Virtual Computer strategy. Then you should read about CODAS Processing and work you way through the post-processing example.
Look at these pages:
If you have a long Traceback that ends like this:
File "/usr/lib/pymodules/python2.7/mpl_toolkits/basemap/__init__.py", line 2067, in drawparallels if t is not None: linecolls[int(lat)].append(t) KeyError: 35
Then you need to install a newer version of Basemap.
First, uninstall the present version. For example if you are using Ubuntu 12.04, uninstall by typing
sudo apt-get remove python-mpltoolkits.basemap
Once you get rid of the older version, here is one way to install a new version:
Eg. if you are running ubuntu, type:
sudo apt-get install git
git clone https://github.com/matplotlib/basemap.git cd basemap cd geos-3.3.3 ./configure make sudo make install cd .. python setup.py build sudo python setup.py install
Then, later, if you have run into a bug that has been fixed, you can update by going into that basemap directory and:
git pull python setup.py build sudo python setup.py install
