Hi IDV'ers,

Can anyone tell me if there is a way to transform coordinate systems using
IDV?  For example, if you have U at some ETA level, is it possible to
transform it into pressure coordinates in Jython?

Thanks,

Paul Graham

You can try:

import ucar.unidata.data.grid.GridUtil as GridUtil
filename = '......'
file_opener = 'file.grid'
ds = makeDataSource(filename, file_opener)
variable = 'Temperature'
display_type = 'planviewcontour'
image_dimensions = (800, 600)
output_name = 'contour2D.png'
setOffScreen(1)
idv.getStateManager().setViewSize(java.awt.Dimension(image_dimensions[0], 
image_dimensions[1]))
temperature= getData(ds.getName(), variable)
altValues = [1000.0, ....]
GridUtil.setVerticalValues(temperature, altValues, RealType.Altitude,
                                 CommonUnits.HECTOPASCAL);

dc = createDisplay(display_type, temperature)

pause()
image = getImage()
writeImage(output_name)
