I have a question.
I have altitude rasters that show too much data. In a small scale map (Pacific Rim countries), i would like to show the mountains and valleys but not every little bump on the surface of the earth, or on the bottom of the ocean. With that much detail when you are at a scale of the Pacific Ocean, it's too busy. The goal is to show the major mountain ranges and valleys. How do I go about thinning out the data. Do I have to convert it first to point data? And if so then what?
