In order to draw ESUs, please click the Add button next to the Elementary Street Units label, near the bottom of the pane and start plotting a line of the map as you would in Earthlight. When you double click on the last committed point an ESU will be created. To add another ESU to the same street click Add again and repeat the process. Please note that during the ESU creation and editing you can utilise Earthlight's snapping capability to create a topological road network. Please take a look at the screenshots below.
After the ESU is plotted you can define its direction using one of the Direction options
To add another ESU to the same street record simply click Add button and start plotting again.
If you would prefer to use another method of finishing ESU creation, please click the right mouse button after adding the last point of the ESU and select Finish from the Context Menu shown on the screen.
When you are happy with the ESU’s you have plotted please click Create Street in case of New Street, or Save Street if the ESU’s were added to an existing street.
The ESUs section also provides the possibility of performing Split, Merge and Reassign operations. To learn more, please visit their respective sites.
