it is a floating point raster like a dem temperature rainfall etc.... they have no table, you have to convert them to integer with or without scaling to retain decimals
The other reason that a table won't exist is that there are too many classes. In such a case you have to go to the the AdvancedArcMapSettings.exe and make changes there
but there are limits to what you can change
Yes I forgot, there is no advance setting utility.
You only hope is finding access at the project level
Now for conventional geodatabases etc, there is information.
With a table size of over 2 billion records, even if that applied to a raster, you would have other issues even if the data type were an integer
Hi! I'm having the same problem. I multiplied my data x 1,000,000 in R to eliminate the decimal point and exported it with datatype INT4S. I used Build Raster Attribute Table in ArcPro to build the attribute table. I can see that that worked, but the Attribute Table option is still grayed out in ArcPro. Any ideas?
