Sentinel-3 pre-processing graph on SNAP 9

fpasino · January 19, 2023, 12:05pm

Hi,
I’m working on the estimate of evapotranspiration and I’m currently stuck on pre-processing of Sentinel-3 data (chapter 3.3.1.9 of UM v1.1.0).
The problems are in Graph Builder.

Setup

Windows 10 Pro 22H2
SNAP 9
Sen-ET SNAP plugin v1.0.0
auxdata from Github repository, commit 247375f on Jun 8, 2022
S3A_SL_2_LST____20221217T094311_20221217T094611_20221218T185045_0179_093_193_2160_PS1_O_NT_004.SEN3 downloaded with SEN_ET > Download sentinel data plugin. (I have also tried others data with same results)

Problem 1

When I try to load the graph sentinel_3_pre_processing.xml with File > Load Graph I receive this error:

Unable to load graph java.ioFileInputStream@2cfab1f7
java.lang.IllegalArgumentException: geoRegion

Problem 2

The graph is correctly loaded if I replace the value of the line 36 <geoRegion>!INPUT_AOI_WKT!</geoRegion> with the corresponding value copied from the file map.wkt (generated by the online tool geojson.io), but when I try to click on Run button, I receive this error:

Error: Invalid number of points in LinearRing (found 3 - must be 0 or >= 4)

map.wkt

POLYGON ((8.336 45.197, 8.336 45.195, 8.34 45.195, 8.34 45.197, 8.336 45.197))

Could you please help me?
Thank you.

you would need to edit the xml file to include the S3 paths on your PC as well as update the AOI with the WKT of your AOI.

More info is found here - Sen - ET plugin (Sen-3 preprocessing graph) - #8 by aforarpit22

If you want, you can compare my edited Graph to yours OR just open mine in Notepad to see where I have made edits and you’ll have to make the edits in yours corresponding to the paths you have on your PC as well as your WKT (polygon location) basis your Area of Interest.
