Question 1

Which GIS data model represents geographic features as a continuous surface divided into equal-sized cells?

Accepted Answer

Raster model

Answer

The raster model divides space into a grid of equal-sized cells, each storing an attribute value, making it ideal for continuous surfaces like elevation or temperature.

Question 2

In GIS, what does the term 'topology' primarily refer to?

Accepted Answer

The spatial relationships between geographic features

Answer

Topology defines the spatial relationships between features, such as adjacency, connectivity, and containment, ensuring data integrity in vector datasets.

Question 3

A planner needs to identify all parcels within 500 feet of a proposed industrial facility. Which GIS operation is most appropriate?

Accepted Answer

Buffer

Answer

A buffer operation creates a zone of specified distance around a feature, allowing identification of all parcels within 500 feet of the facility.

Question 4

What is the primary purpose of a geodatabase in GIS?

Accepted Answer

To store, manage, and query spatial and attribute data in a structured format

Answer

A geodatabase is a structured container for storing geographic datasets, supporting spatial relationships, domains, and rules for data integrity.

Question 5

Which map projection preserves area and is most suitable for thematic maps showing regional distribution of environmental data?

Accepted Answer

Albers Equal-Area Conic

Answer

The Albers Equal-Area Conic projection preserves area relationships, making it ideal for thematic maps where accurate size comparison between regions is important.
