Tiff Raster - Barvy mimo ArcGIS, černobíle v ArcGIS

Question

<\/HEAD>Extrahoval jsem podsekci velkého rastrového souboru. Soubor se zobrazuje v plných barvách mimo ArcGIS, ale po importu do ArcMap nebo Pro se zobrazuje černobíle, přestože je nastaven na zobrazení v barvě/všechny pásma.<\/P> <\/P> Zatím jsem zkoušel přepočítat jeho statistiky v Catalog.<\/P> <\/P> <\/P> Děkuji<\/P> Gavin<\/P><\/BODY><\/HTML>

Hi,
the file is just fine 🙂 But you should recreate the overviews - they seem to be corrupt - and make sure the file is interpreted as "processed" and not stretched when loaded:

So proceed like this:

Go to the folder you stored the data in and delete the *.ovr file

In Catalog /(or Folder view in Pro) open the properties of the dataset and define the source type as "Processed".

In Catalog /(or Folder view in Pro) open the properties of the dataset and REMOVE the NOData value (set to 255,255,255) to be empty.

Now right-click the image again and create new Pyramids - Nearest Neighbor/LZ77 works fine for this data
When adding it to the display now, everything should be fine and since you did Nearest/LZ77 you can still set 255,255,255 background color to be transparent (in the Symbology of the layer) and it will look fine on all levels. I attached the result
