Identifying areas of high light intensity

Hi all, I have only tried using IDW for precipitation but now I would like to check if IDW is suitable for interpolating light intensity.

Thanks!

There is generally no one interpolator suitable for any data type, it is the pattern and nature of the data of the data that is important. Looking at this from the opposite perspective, given the same X,Y,Z numerical data...it doesn't matter what it is called, the output results will be the same for any interpolator regardless what you call the data.

Hi Dan

Thanks so much for your reply. But just to double-check, is it

geographically correct to interpolate light intensity data?

Picture a lit parking lot. If you given the task to ensure there was sufficient lighting to comply with local regulations, you would need a quantitative measure of the lighting pattern. if you obtained a decent set of field data measuring the illumination level (say in lux) at various locations, you could produce a contour map of the light pattern to check for areas which might not be sufficiently illuminated. I am sure there are many such examples
