I have a huge database with sightings from whales and dolphins.
Now I want to sort them and want to make it easy for people to select in this content between e.g. the different whale types and the different years and so on. So I was thinikng about that their is for each year a single layer. But that should be something like a query. Because if their is a "new year" for example 2015 than I have no layer for this year. Thats the problem if i would do it manually.
I have no idea how to sort this problem.
Have you any Idea how to make it in ArcGIS?
Would be very thankful for any suggestions.
