I have a data from the Weather station with SWEmax (snow water equivalent) collected over 40 years. I need to interpolate the data over my river's watershed and then, somehow, determine the differences which might have happened over this time.
- Which tools do I need to use in ArcGIS 10.1 to achieve this?
- Do I need to make z-surfaces first and then take statistics from them?
- Is the best way to show the differences is to use a diagram with years on the x-axis?
