Read 2d data array from the .awx file, plot the data, save the plot to .png file.
Following is an example script:
fn = 'D:/Temp/FY/FY2D_TBB_IR1_OTG_20080630_1315.AWX' f = addfile_awx(fn) data = f['var'][:,:]
axesm() geoshow('country', edgecolor='k') geoshow('cn_province', edgecolor='k') layer = imshowm(data, 20) colorbar(layer, label='K') title('TBB - AWX')
savefig('D:/Temp/test/fy2d_tbb.png', width=600, height=700, dpi=150)
`def geoshow(*args, **kwargs): ''' Display map layer or longitude latitude data.
Syntax:
--------
geoshow(shapefilename) - Displays the map data from a shape file.
geoshow(layer) - Displays the map data from a map layer which may created by ``shaperead`` function.
geoshow(S) - Displays the vector geographic features stored in S as points, multipoints, lines, or
polygons.
geoshow(lat, lon) - Displays the latitude and longitude vectors.

Python?......I'm a javaer.I don't konw how to use it.So I still don't konw how to parse AWX to PNG
I suggest you to learn Jython to understand the code.
OK. I have read you some code. And I saw you parsed it successfully,such as: Is it right?But, AWX file is belongs to SAT96 or SAT2004. Their standard like this: You just had the data: No NO1-File-Head and NO2-File-Head. Is it right or haven't achieve it?
Please find the awx file decoding code here: https://github.com/meteoinfo/MeteoInfo/blob/master/MeteoInfoLib/src/main/java/org/meteoinfo/data/meteodata/awx/AWXDataInfo.java
I want to change a .awx file to .png. But I don't konw how to paser it. Please help me, provide an idea.
