Connecting Streets to Traffic Lights in GIS

What settings should you have turned on when digitizing streets to ensure they connect with traffic light features in the electrical network?

A. vertex snapping

B. point snapping

C. end snapping

D. edge snapping

Answer:

Final answer: To digitize streets and connect them to traffic light features in an electrical network, the correct setting to use is end snapping.

Explanation:

When digitizing streets and ensuring they connect with traffic light features in an electrical network, you should have end snapping turned on. End snapping allows you to seamlessly connect the endpoints of streets, also known as connecting nodes, to other features within a Geographic Information Systems (GIS) vector dataset, which can include point data sets representing traffic lights.

In GIS, edge endpoints are specifically called the Start Node and the End Node, with the former being the origin and the latter being the destination of the directed edge. Considering the fundamental vector types in GIS, which include points, lines, and polygons, end snapping is pertinent to the context of lines where streets are graphically represented.

Since traffic lights are effectively modeled as points (noting that in GIS discourse, nodes are intersections of line features and not standalone features), having end snapping active ensures that streets end precisely at the location of traffic lights if they are supposed to be connected.
