Hello,

When I prefer a raster dataset to include an Attribute Table, I need to create an Integer version of this first (using the Int tool). That's fine, and I understand why. ...However, sometimes this goes ahead and creates the Attribute Table, as well; whereas other times I have to take the next step and Build an Attribute Table using that tool.

...Can anyone explain why sometimes I do, and sometimes I don't?

In addition, I notice that sometimes the added field is named 'Value', and other times it's 'gridcode'.

Keep track of the physical size, bit type and raster type (esri grid, gdb raster, tif, img etc) to see which one requires you to build a raster table

gridcode is usually associated with

Raster to Polygon (Conversion)—ArcGIS Pro | Documentation

so again what type of raster directly results in gridcode (esri grid?) being in the raster attribute table


... sort of retired...
