Hello,
I am an environmental biologist for a state agency and I use ArcMap frequently to display species occurrence coordinates throughout the state in different counties and/or waterbodies. I am working with 80 different layers each accompanying occurrence information for a single species. When I load the project it projects all the points at first, but after some time passes as I toggle different species layers on and off, soon ArcMap fails to project and points. Problem is solved when I clear the cache but then I have to reload the entire project which takes some time for it to load. Can someone tell me, why is this happening and is there a solution?
