Hi everyone! I encountered a problem while attempting to use the get_samples method of the Imagery Layer from the Python API. I accessed the Landsat Imagery layer, applied the NDVI raster function, but the get_samples method does not return the correct values. This is the code import arcgis from arcgis.raster.functions import * from arcgis.geocoding import geocode ## skipped connection lines # access Landsat Imagery landsat_item = gis.content.search('Multispectral Landsat', 'Imagery Layer', outside_org=True)[0] landsat = landsat_item.layers[0] # Create geometry area = geocode('Bucharest, RO', out_sr=landsat.properties.spatialReference)[0] geom = arcgis.geometry.Geometry(area['extent']) # Get samples ndvi_lyr = ndvi(landsat, '5 4') sam = ndvi_lyr.get_samples(geom, sample_count=1) sam[0]['value'] # get only the pixel values The output is: '1405 1198 1012 927 1367 1146 857 9 2720' I expected to get the values as NDVI values (-1 to +1 interval), not unprocessed data. Am I doing something wrong? Thanks for any help, Alin
