Hello
I am trying to work on some raster via Python API. even if the documentation and the videos are very explicative I didn`t find anything on this subject.
As far as I know a Mosaic dataset is a special type of `layer` where each attribute in the attribute table points to a specific raster stored somewhere.
now let`s say that I want to do some processing on some rasters in the mosaic. for example a minus operation on two rasters stored in the mosaic.
how do I access a single raster into the mosaic? this is the procedure that I am using.
try:
gis = GIS("https://Myportal", username="usr", password="pwd")
except Exception as e:
print("An exception occurred: ", e)
#accessing my mosaic dataset item
lyr1 = gis.content.get('7d562782877aec8fc3')
#accessing my mosaic layer
lyr1 = lyr1.layers[0]
#filtering my mosaic layer to isolate only one raster inside it
filtered_lyr1 = lyr1.filter_by(where="objectid = 10")
filtered_lyr2 = lyr1.filter_by(where="objectid = 9")
#applying processing functions to the layers
processedLyr = apply(filtered_lyr1 , 'DBX_Bathy_Hillshade')
