How to Ensure Your Streams Connect Correctly in GIS Environment

What should you have turned on when digitizing streams to ensure they connect at their nodes?

a. point snapping b. vertex snapping c. edge snapping d. end snapping

Final answer:

To digitize streams and make sure they connect at nodes correctly, end snapping should be used in a GIS environment.

When digitizing streams to ensure that they connect at their nodes properly, you should have end snapping turned on. End snapping is the precision tool that ensures stream segments are connected precisely at their endpoints, which is essential for maintaining the continuity and flow direction of the hydrological data in a Geographic Information System (GIS). Having end snapping enabled helps to avoid errors such as 'dangling' ends that do not connect to anything or overlaps that can distort data analysis.
