Tiff Raster - Farbe außerhalb von ArcGIS, Schwarz-Weiß in ArcGIS

Question

<\/HEAD>Ich habe einen Ausschnitt eines großen Rasters extrahiert. Die Datei wird außerhalb von ArcGIS in voller Farbe angezeigt, aber wenn sie in ArcMap oder Pro importiert wird, wird sie trotz der Einstellung auf Farbdarstellung/alle Bänder schwarz-weiß angezeigt.<\/P> <\/P> Ich habe bisher versucht, die Berechnung der Statistiken im Katalog neu auszuführen.<\/P> <\/P> <\/P> Danke<\/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
