Map Visualization Quiz #3

Which projection preserves straight meridians and parallels forming a rectangular grid?

• Mercator Projection

• Robinson Projection

• Lambert Projection

• Azimuthal Projection

A major limitation of the Mercator projection is that it:

• Distorts distances near the equator

• Exaggerates area near the poles

• Compresses continents near the poles

• Eliminates directional accuracy

A major disadvantage of choropleth maps is that they:

• Cannot display regional data

• May misrepresent data when region sizes differ greatly

• Do not use colors

• Only work with geographic coordinates

In an equirectangular projection, latitude and longitude are represented as:

• Curved lines

• Straight perpendicular lines

• Circular arcs

• Irregular polygons

Which property of map projections is most important for accurate navigation routes?

• Area preservation

• Angle preservation

• Distance preservation

• Population accuracy

Which statistical technique improves interpretation of choropleth maps?

• Raw totals

• Per-capita normalization

• Random sampling

• Arbitrary color scales

Which dataset is most appropriate for a choropleth map?

• Individual GPS locations

• Population density by region

• Airline routes between cities

• Daily weather observations

A researcher wants countries resized by population so high-population countries appear larger than actual land area. Which map type is this?

• Cartogram

• Choropleth map

• Topographic map

• Dot map

A map designer wants to create a balanced world map that reduces distortion of area, direction, and distance simultaneously.

• Mercator projection

• Winkel Tripel projection

• Equirectangular projection

• Conic projection

A transportation authority wants to visualize real-time traffic congestion across a city, updating the map every few seconds using live data. Which type of map system is most suitable?

• Data-Driven Map

• Static Map

• Paper Map

• Satellite Map
