Weighted Overlay cell size?

MauriceHoneyford

Hi All,

Could someone please offer an opinion on this please?

I'm creating a relatively simple density overlay.

To do this I'm using two rasters I've interpolated using IDW that were created at a cell size of 100 (i.e. pretty smooth interpolation).

However, the output of the density overlay is pretty blocky - blockier than my input rasters.

Is there an environment setting or otherwise that I should be using to make the cell size of the density overlay raster smoother?

Many thanks all.

If you are using anything on the Spatial Analyst menu, Mikael, complete the CellSize tab in the Options dialog.  If you are using an ArcTool, there is an analogous setting buried in the Environments dialogs.

Hi Bill,

Thanks for the info. Sorry for late reply - have been away.

Will try when back in the office tomorrow!

Cheers.
