Polygons are not the only type of feature you may need to split. Lines often need to be split as you add other features to the same layer to maintain the correct connections. Lines often form a network that’s used to travel across, such as roads, railroads, sidewalks, and trails. Travel is not limited to transportation. Utilities also use linear features to move water, sewer, electricity, and communications from one point to another. Other systems, such as emergency dispatch systems, rely on linear data from GIS as well. So, we must maintain these layers correctly.

In this recipe, you will draw new sewer lines based on a scanned and georeferenced plot. Once you’ve drawn the new sewer lines, you will split them where they connect to manholes, as shown on the plot, so that you can get accurate measurements of each section of the sewer line between the manholes.
