Copernicus 30 M Global DEM GPT

[lepanda]

I am just wondering if Copernicus 30 M Global DEM auto download is supported when using the graph processing tool (GPT). I can use it when I use the basic snap GUI, but when I try and run commands like GPT topophase removal, or GPT backgeocoding, it says the Copernicus 30 M Global DEM is not supported.

Thanks

Hi lepanda
According to this post it is working:

GPT Terrain Correction using Copernicus 30m dem fails

I looked to see if this problem was already addressed in this forum. I was not quite sure so I will go ahead and post it. When doing terrain correction with gpt and Copernicus DEM, a java.lang.NullPointerException results (edited for readability): gpt Terrain-Correction -t S1A_IW_GRDH_…OB_CAL_TC -Ssource=S1A_IW_GRDH…_OB_CAL.dim -PpixelSpacingInMeter=10.0 -PmapProjection=“WGS84(DD)” -PdemName=“Copernicus 30m Global DEM” INFO: org.esa.snap.python.gpf.PyOperatorSpi: Python operator ‘py_sambuca…

Do you set the parameter like this “Copernicus 30m Global DEM”?

Im using it in backgeocoding for s1 images and it is throwing this error. I am setting it the same way though.

Hi, I am using snappy for DEM generation. In the terrain correction step, which is my last step I provided the demName parameter like this parameters.put(‘demName’, ‘Copernicus 30m Global DEM (Auto Download)’)

It throws me the following error
Copernicus 30m Global DEM (Auto Download)’ is not supported

Try it without (Auto Download), just Copernicus 30m Global DEM
