Hi Ben,
One thing still confuses me is that IDV can generate the image directly, why to
go an extra step
to generate the NC file and then using Python to create images.
Anyway, the procedures in the IDV is through the IDV script ISL. Here is the
information about ISL in the following URL:
https://www.unidata.ucar.edu/software/idv/docs/workshop/isl/index.html
In the IDV, you can run the ISL in a command line as:
runIDV /home/idv/isl/basic1.isl
and you can setup a bash job to do it offscreen.
Here is a example of generating output:
<?xml version="1.0" encoding="ISO-8859-1"?>
<isl debug="true" loop="1" offscreen="true" sleep="60.0minutes">
<bundle clear="true" file="${islpath}/aaaaa.xidv" wait="true"/>
<export file="${islpath}/aaatest" what="netcdf"
display="class:ucar.unidata.idv.control.ContourPlanViewControl"/>
<image file="${islpath}/aaaaa.png"/>
</isl>
In this ISL example, you generate an aaaaa.xidv bundle that is a simple contour
plan view display of one of your data. If you need to do
multiple files, you can use setfiles command like:
<isl debug="true" offscreen="false">
<bundle file="test.xidv">
<setfiles datasource="datasource1" file="file for first data source"/>
<setfiles datasource="datasource2" file="file for 2nd data source"/>
</bundle>
<image file="test.png"/>
</isl>
Well, there is a learning process, let me know if you need help.
