Visualisation and analysis application for atmospheric data

Copyright (C) 2002-2022 S[&]T, The Netherlands. VISAN 4.3.2 Release Notes VISAN is a Visualisation and Analysis application that was designed to be a front-end for CODA and HARP, but is general enough to be appropriate for a much wider range of applications. VISAN provides a full Python command line interface that allows you to read and inspect instrument product data via CODA or HARP, manipulate the data, and create advanced 2D Plots and Worldplots. The currently supported platforms are Windows 10, Linux, and macOS (10.9 and higher). Installation ============ VISAN is available exclusively as a conda package. For Linux, make sure that you have X11, OpenGL libraries, and Gtk 2.x (including Glib 2.x, Pango, ATK, etc.) installed. To install the binary version for your platform you will first need to install Anaconda or Miniconda, then activate the conda environment in which you want to install VISAN. We recommend creating a dedicated environment for VISAN: $ conda create -n visan $ conda activate visan and within this environment install VISAN itself using: $ conda install -c conda-forge visan The VISAN application can then be found in your conda environment. To build VISAN from source, clone the VISAN github repository and create a conda environment with the VISAN application as follows: $ conda env create -f environment.yml $ conda activate visan-build $ cmake -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX $ make install Documentation ============= Full documentation in HTML is included with the VISAN software. A version matching the latest development status on GitHub can be viewed at: http://stcorp.github.io/visan/ Download ======== The VISAN software can be downloaded from GitHub: https://github.com/stcorp/visan/ VISAN Developers S[&]T, The Netherlands
I'm sorry if this is a really naive question. But I just can't manage to import my file: S5P_OFFL_L2__NO2____20190316T001448_20190316T015618_07358_01_010202_20190322T020430.nc
with harp.import_product()
:
It always gives me this error:
raceback (most recent call last): File "<input>", line 1, in <module> File "/home/robin/miniconda3/envs/visan/lib/python3.7/site-packages/harp/_harppy.py", line 1134, in import_product raise CLibraryError() harp._harppy.CLibraryError: error parsing unit database (/home/robin/miniconda3/envs/visan/share/harp/udunits2.xml)
Does anyone might have a clue what I could do? Any help is super appreciated:)
Thanks a lot:)
When I try to save an image from the World Plot or 2D Plot window, it is not possible to change the directory. Clicking on ‘Browse…’ gives the following error message:
Traceback (most recent call last):
File “D:\lenka-hp\soft\Anaconda3\envs\visan_env\lib\site-packages\visan\plot\typedsavefiledialog.py”, line 217, in OnBrowse
filename = wx.FileSelector(“Save As…”, default_path=directory, flags=wx.SAVE, parent=self)
AttributeError: module ‘wx’ has no attribute ‘SAVE’
Using wplot(..., colortable="path/to/file")
does not work, since providing a wrong name does not result in an exception internally, and therefore the plot.GetColorTable(dataSetId).Import(kwargs.get("colortable"))
never gets called.
We should also include the colortable file format in the documentation.
The VISAN worldmap plot currently only shows shorelines from the GSHHS dataset, but there is a demand for showing political borders as well.
The updated version of the GSHHS dataset, GSHHG, apparently also includes national boundaries.
Updating VISAN to support this new dataset will thus likely be the easiest way to introduce this feature.
I used the following instructions:
conda install --channel https://conda.anaconda.org/stcorp visan
But Anaconda told me:
PackagesNotFoundError: The following packages are not available from current channels:
Hello!
When I am trying to change speed of animation in the plot created by wplot(), I am getting an error:
Traceback (most recent call last):

This happens both when I use arrows to increment/decrement by one and when I enter the number myself.
The version of VISAN is the following:
VISAN 4.0 (Python 3.7.4, wxPython 4.0.4, VTK 8.2.0, NumPy 1.16.5, CODA 2.21, HARP 1.9.2)
