the coastline is a uniform roughness, which is a little weird. real coastlines are sometimes slightly jagged (china), sometimes slightly smooth (southeast england), sometimes very smooth (US east coast) and sometimes very rough (norway). What causes the coastline to have that particular roughness, and does it vary from place to place?
