What is the best way to show the difference in elevation between 0-4 feet for about 100 points. I have the spatial extension and I would like to show change over time. Any suggestions?
The map will be for a reef that is going to be restored. I will need to show the depth change over time. The downside is the depth change will more than likely be very minimal.
As Neil says... interpolate for the two time periods, then subtract the results. Interpolation approach should use the same method... what is appropriate is a whole new discussion...
Methods are found in the help topics, make sure you read the 'how... works' sections if present
