Raster Calculator Flow Accumulation Failed to execute，GRID.

[HuaxinWang]

I use a raster calculator to get Flow Accumulation above 3000 or 5000.

But it could not execute.

I have done this calculator with other rasters many times and they all worked out very well.

I don't know why this time is not ok.

I googled it but could not find a solution.

Please help me out of this.

Thank you very much.

Doe it just fail for esri grid output? or did you try saving to a *.tif in a folder?

It worked out when saved as .tif.

I will find out why.

Woo.

Thank you very much for your explanation.

It would take me a while to find out that.

I will study it.
