Hi

I tried to use Flow Direction and Flow Accumulation tools with several different projected grids and achieved bad results (see screenshot):

1. FlowDir tool produces some strange values: 9, 66, 68, 72, 132, 136, 144. What do they mean?

2. FlowAcc tool doesn't work properly. It seems like water flows to the top of the hill! ))
