First post!  I am new to GIS, so bear with me.

I created a flow direction layer, and the layer has more cells than the input surface layer.  How can this be?  The reason this is a problem for me is that I am using the direction layer to calculate flow accumulation, and I would like to translate this to drainage area. 

Thanks in advance
