I am using ModelBuilder to perform inverse distance weighting. I would like to interpolate values using a point file with values for several unique dates - resulting in a raster dataset for each unique day. My data is in long format where each row has a value for each coordinate/date.
I have tried to create a model that performs the IDW on each unique day, using row iterator to iterate through each "date". It runs, but I don't think it's correct. Here is the model.
This results in a raster dataset for each unique day. The problem is, each raster is identical. They should not be - the interpolated values should vary each day. Maybe I am using the wrong iterator.
Can you please suggest ways to get this to work?
