On one side, I have a table that contains 7 colomns and one of it is a unique value, from 1 to 50 (VALUE field). On the other site, I have a raster with the VALUE field (from 1 to 50) and the COUNT fiels. I can do a right-click(on the raster)=>joins and relates to join my table to the RASTER (it appears in the attribute table from the raster).
But here is my problem, I can't make this join permanent... Is there a way to do so? exporting the raster with the join table doesn't work...
The way raster tools work, it really makes sense to keep attributes in a separate table if you can, as any subset or clipping of the raster data in most cases will lose all attributes except VALUE and COUNT.
That said, I believe the Join Field tool will do what you want.
After you join all the tables you want, you can do an Extraction by mask or something like that and the new raster dataset will contain all the table`s information. I`ve done that on the World Soils Map from FAO. It worked really nice and I also extracted my area of interest.
Exporting VATs to independent tables then joinig those tables back to combined GRIDs worked:) Somtimes if I did a join directly back to the GRID, I would only get the column names of the joined table, but none of the values. It would be nice if the Combine function or others allowed you to keep descriptive attributes
