Cartography and Geospatial Analysis Questions
Which type of projection is commonly used for small-scale maps of the world?
-
Mercator projection
-
Lambert conformal conic projection
-
Transverse Mercator projection
-
Azimuthal equidistant projection
A
Correct answer
Explanation
The Mercator projection is widely used for small-scale maps of the world due to its ability to preserve angles and directions, making it suitable for navigation and general reference purposes.
What is the primary role of a cartographer in planning?
-
To create maps
-
To collect data
-
To analyze data
-
To make planning decisions
A
Correct answer
Explanation
The primary role of a cartographer in planning is to create maps that effectively communicate spatial information to stakeholders, supporting the planning process.
Which type of map is commonly used for site planning?
-
Topographic map
-
Cadastral map
-
Zoning map
-
Transportation map
B
Correct answer
Explanation
Cadastral maps are used for site planning as they provide detailed information about land ownership, boundaries, and property lines, which is essential for planning and development purposes.
