allocating the value of one pixel to nearest pixels

Discussion created by elizabethmcnamee on Nov 10, 2010

I have a point layer with the volume of water at that point as the value, and a raster of crop irrigation water requirements for each pixel. I want to allocate the volume of water at each point to the nearest irrigation pixels, continuing outwards until there is no water "left". Does anyone know how to do this? I could convert the point layer to a raster, but the hard part is distributing the water across the irrigation grid. Any suggestions at all?

Thank you,
