Before you can plot a point on the map you must first select a nearby street segment.

Before you can plot a point on the map you must first select a nearby street segment.

• A. Street block
• B. Street intersection
• C. Street name
• D. Street segment

Answer: (D)

When placing a coordinate on a road-network map, you anchor the location to the actual road geometry. The essential unit for this is the street segment—the stretch of road between two intersections. This provides a concrete, measurable line you can place the point along, allowing precise positioning (for example, a specific distance from the segment’s start or a particular percentage along it). A street name alone isn’t enough because many segments share the same name, which wouldn’t pinpoint the exact location. A street intersection gives only a single point, not where along the road the point lies. A street block describes an area, not a precise location on the road itself. So, selecting the street segment first gives you the exact linear feature needed to plot the point accurately.
