Hi :-)

I'm working with Land Cover data with 5 classes (Polygon; 1km).
I created a vector grid (3km*3km) which fits my raster and vector layers. the snapshot will explain what I Mean:

[ATTACH=CONFIG]19628[/ATTACH]

In my results I expect to calculate the ration or percentage of each class in each grid:

[ATTACH=CONFIG]19629[/ATTACH]

For this purpose I Unioned the grid with Land cover. The results looks like:

[ATTACH=CONFIG]19630[/ATTACH]

with the attribute table of:

[ATTACH=CONFIG]19631[/ATTACH]

I'm looking for an attribute which I can see different classes in of Grid, as I explained earlier for my purpose, so I export it to excel and calculate the percentage of each class in each grid.

Any help is Appreciated,
Many thanks in advance,
Sadra
