GIS Limitations Quiz

What are the limitations of a GIS?

• High cost of implementation

• Unlimited data storage

• Instant data processing

• No need for technical expertise

Answer explanation

The correct choice, 'High cost of implementation', highlights a significant limitation of GIS, as setting up such systems often requires substantial financial investment, unlike the other options which are not true limitations.

Under what conditions might the technology hinder problem solving, rather than help?

• When data is inaccurate

• When data is perfectly accurate

• When technology is always reliable

• When there is no need for analysis

Answer explanation

Technology hinders problem solving when data is inaccurate, as it can lead to incorrect conclusions and decisions. Accurate data is essential for effective analysis and problem resolution.

What does the map in the image primarily depict?

• Climate zones of North America

• Major cities in North America

• North American English dialects based on pronunciation patterns

• Historical trade routes in North America

Answer explanation

The map primarily depicts North American English dialects based on pronunciation patterns, highlighting regional variations in speech rather than climate, cities, or trade routes.

Which of the following is a component of the geographic coordinate system?

• Latitude

• Mercator

• Peters

• Projection

Answer explanation

Latitude is a fundamental component of the geographic coordinate system, representing the north-south position on the Earth's surface. The other options, such as Mercator and Peters, refer to map projections, not components of the coordinate system.

What is a type of projected coordinate system?

• Longitude

• Parallel

• Mercator

• Meridian

Answer explanation

The Mercator projection is a type of projected coordinate system that represents the globe on a flat surface, preserving angles and shapes, making it useful for navigation. Longitude and meridian refer to geographic coordinates, not projections.

Which term is associated with geodesy?

• Parallel

• Peters

• Projection

• Geodetic datum

Answer explanation

A geodetic datum is a reference framework used in geodesy to measure and represent the Earth's surface. It provides the necessary coordinates for mapping and navigation, making it the most relevant term associated with geodesy.

Which of the following is not part of the geographic coordinate system?

• Latitude

• Longitude

• Peters

• Meridian

Answer explanation

The geographic coordinate system consists of latitude and longitude, which define locations on the Earth's surface. 'Peters' refers to a map projection, not a coordinate system component, making it the correct answer.

What does the Geographic Coordinate System use to define locations on Earth?

• A two-dimensional grid

• A three-dimensional spherical surface

• A flat map projection

• A linear scale

Answer explanation

The Geographic Coordinate System defines locations on Earth using a three-dimensional spherical surface, which accounts for the Earth's curvature, unlike a flat map projection or a two-dimensional grid.

How long has the Geographic Coordinate System been used as a worldwide location reference system?

• 500 years

• 1,000 years

• 2,000 years

• 3,000 years

Answer explanation

The Geographic Coordinate System has been in use for approximately 2,000 years, originating from ancient Greek astronomy and navigation, making it the correct choice for a worldwide location reference system.

In what units are geographic coordinates measured?

• Degrees, minutes, seconds

• Meters, kilometers

• Pounds, ounces

• Liters, milliliters

Answer explanation

Geographic coordinates are measured in degrees, minutes, and seconds, which represent the angular position of a point on the Earth's surface. The other options refer to measurements of distance or volume, not coordinates.
