Question

_____ is an intersection point where two or more lines meet.

Hint:

Think of a node like an intersection on a road map. It is the exact point where two different streets cross each other.

Answer 1

Step 1: Concept
Vector data models in GIS use specific geometric definitions to represent real-world features and their spatial relationships (topology).

Step 2: Meaning
In a topological network, the specific points where lines (arcs) connect, intersect, or terminate have a specific technical name.

Step 3: Analysis

• A vertex defines the intermediate shape of a line where it bends but does not intersect another line.
• An arc or edge is the line segment itself.
• A node is the fundamental topological junction point where two or more arcs meet, or where a single line starts or ends.

Step 4: Conclusion
The formal term for this intersection point in GIS topology is a node. Final Answer: Node
