Output raster of Classify pixels using deep learning is blank

MelodyYu

Dear all, 

When I tried to use the tool ' ClassifyPixelsUsingDeepLearning', I got the result raster in the contents list and the folder. But it's compeletely blank in the map workspace.

Could anyone can help?

Hi @MelodyYu,

Thanks for sharing the information. I have few suggestion which I would like you to try:

1. With the output raster which you are not able to see and seems blank:

• In the below screenshot we can't see "HR_Luchtfoto_2_80cm" raster in the map and seems blank raster:

• But when I use explore and click on the map I can see the rasters class values:

 

• By adding the raster in a new map we can see the raster in the map:

 

• You can try this for your output raster.

2. Changing cell size in Classify Pixels Using Deep Learning tool:

• The Land Cover Classification (Aerial Imagery) - Overview  pretrained model works best with 10 cm cell size.
• Use 0.1 value for Cell Size parameter in Environments tab of Classify Pixels Using Deep Learning tool:

   

3. By visual interpretation the raster which you shared doesn't seem like it's spatial resolution (cell size) is 10 cm so you can also try High Resolution Land Cover Classification - USA (https://www.arcgis.com/home/item.html?id=a10f46a8071a4318bcc085dae26d7ee4) which works for raster with cell size between 80cm - 1m.
