Which Interpolation should I Use?

MichaelTrevino — Mon, 07 May 2012 12:51:30 GMT

I have Water and Electric consumtion data that I am attempting to make into a raster data set. I would like said raster to look like what was created before but, cannont figure out what type of Interprolation I should use and what parameters to set. The water and electric consumption data is now joined to an 'Address Points' layer so that the useage is on top of the parcel that used the water/elevtricity.

How do I go from this...

I would probably recommend one of the density tools based on your screenshots. I am not sure if you want to truly interpolate to create a complete surface. The Point Density tool will probably create the desired output.

I agree with the above comment but, Looks like IDW with a very high power, set the neighbors to 1. Experiment with the powers and neighbors. Go low on Neighbors and High on Power. Could set the search radius to fixed, and set that to a very low number, like half the distance from point to point/house to house. Good luck.
