Hi, i’m trying to get NDVI value for polygone ,
Please any solution .
i get this message :
thanx

Hi @SAMED

Could you please let us know where this happens? Is this an example from eo-learn?

Additional comment: your eo-learn version seems to be a bit outdated: could you try with the latest (0.10.1)?

Hi @batic Thank you for your quick response !

yes it’s from eo learn
the polygon is a Polygon Z (3D)

Honestly, I’ve never worked with a Polygon Z before, so it might be there is an issue there… Could you try something along the lines of this:

# poly is your polygon, e.g. poly = geodataframe.iloc[0].geometry
poly_wkt = poly.to_wkt()
shapely.wkt.loads(poly_wkt)
