QUESTIONS AND ANSWERS ━━━━━━━━━━━━━━━━━━━━━━━━━
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
════════════════════════════════════════ SECTION 1: MAPPING
FUNDAMENTALS ════════════════════════════════════════
1. What is the primary purpose of a cadastral map?
A. To show topographic features of the land
B. To display transportation networks and road hierarchies
C. To record land ownership, boundaries, and parcel identification
D. To illustrate population density by region
, E. To depict vegetation cover and land use patterns
✓ Correct Answer: C. To record land ownership, boundaries, and parcel
identification
EXPERT RATIONALE: A cadastral map is specifically designed to show land
ownership boundaries, parcel identification numbers, and property lines for legal
and taxation purposes, making it the foundation of property assessment systems.
2. Which of the following best defines a parcel?
A. A unit of measurement used in surveying
B. A contiguous area of land under one ownership described by a single legal
description
C. A grid cell used in raster GIS analysis
D. A polygon feature representing a census block
E. A topographic unit used to classify terrain
✓ Correct Answer: B. A contiguous area of land under one ownership
described by a single legal description
EXPERT RATIONALE: A parcel is the fundamental unit in cadastral mapping — it
represents a tract of land with defined boundaries, owned by one party and
described in a single legal description for assessment and tax purposes.
3. What does the term "map scale" refer to?
A. The accuracy level of a map
, B. The ratio between a distance on the map and the corresponding distance on
the ground
C. The number of layers contained in a GIS dataset
D. The projection system used to create the map
E. The resolution of satellite imagery used
✓ Correct Answer: B. The ratio between a distance on the map and the
corresponding distance on the ground
EXPERT RATIONALE: Map scale is the proportional relationship between map
distance and real-world distance. A scale of 1:24,000 means one unit on the map
equals 24,000 of the same units on the ground.
4. A map with a scale of 1:1,200 is considered what type of scale?
A. Small scale
B. Medium scale
C. Large scale
D. Micro scale
E. Regional scale
, ✓ Correct Answer: C. Large scale
EXPERT RATIONALE: A large-scale map shows a small area in great detail.
1:1,200 is commonly used for parcel-level mapping because it provides sufficient
detail for property boundary representation.
5. Which map scale would be most appropriate for a county-wide overview
assessment map?
A. 1:1,200
B. 1:2,400
C. 1:600
D. 1:100,000
E. 1:400
✓ Correct Answer: D. 1:100,000
EXPERT RATIONALE: A 1:100,000 scale is suitable for showing large geographic
areas such as counties in a single view, though it sacrifices parcel-level detail. Larger
scale maps like 1:1,200 are used for detailed property work.
6. What is a map legend?
A. The title of the map
B. A key that explains the symbols, colors, and patterns used on the map
