We are trying to to make printed map books for our electric linemen. They would like to see the direction that the current flows along the line. We have generated arrows that show the direction but our line features are only as long as the span between poles. So our arrows when zoomed out very far are increadibly cluttered i attached an image off a sample page of the map book. Is there any way to reduse the amount of arrows that appear along a line to clean up the map so we can give our guys some offline maps when/if our servers are down or cell service is spotty.
