The fields of the attribute table of the raster in the catalog window

I�??m wondering why the �??catalog view�?� of doesn�??t show the fields of the attribute table of raster as main component of its properties while it does so for polygons, polyline and points?

Thank you for the help,

Jamal,

You can't have a feature class of point, line, or polygon without also having an attribute table.  "Fields" is something that is common to all of those and thus they have a shared UI.  Raster data on the other hand, does not always have a table.  Multiband imagery doesn't support tables, nor does 32 bit float.  Integer data can support a table, but depending on the data it may be built automatically or it could be up to you to run the Build Raster Attribute Table tool to force a table to be built.  Because of the lack of uniformity among the various types of raster data with respect to attribute tables, they do not have a shared "Fields" tab in the properties dialog.

Eric

I appreciate your continuous help Erc.

I tried to create a table for the �??rainfallvolume�?� raster but sounds not to work.

What might be the reason in this case?

That raster is floating point.  You must have an integer raster to build attribute tables.
