Thank you for your input. Let me ask me question another time. I have 4 drainage raster dataset for the four states such as IA, WI, IN and MS. Raster files contain three categories of pixel (pixels 1,2 and 3 and these are for three different area counts. 1 corresponds to less than 607 pixels, 2 indicates 607 to 10,000 pixels, and 3 indicates > 10,000 pixels. 607 pixel is 15 acres and so class 2 and 3 would be more than 15 acres) and cell size of each raster is 10m. Yes, I have to create a 5 minute dataset that provides the area of the grid cell suitable for drainage, by summing the area in classes 1, 2 and 3. Then I have to create a fraction of grid cell map by dividing the sum by the grid cell area.
Can you please suggest me something on that.
-Thank you!
