GIS Cartography and Visualization 4

Question 1

In GIS, what is a 'hillshade' raster used for?

Accepted Answer

Simulating the shadow effect of sunlight on terrain for visual relief

Answer

A hillshade raster simulates the illumination of a surface by a hypothetical light source, enhancing the three-dimensional appearance of terrain.

Question 2

What is the primary purpose of map generalization?

Accepted Answer

To simplify features appropriately for a given scale and purpose

Answer

Map generalization simplifies the complexity of geographic features so the map remains legible and useful at a specific scale.

Question 3

Which color scheme is recommended for a sequential thematic map showing values from low to high?

Accepted Answer

Single-hue light-to-dark gradient

Answer

A single-hue sequential scheme (e.g., light yellow to dark green) intuitively communicates ordered magnitude from low to high values.

Question 4

What does a 'neatline' represent on a map layout?

Accepted Answer

The border or frame that encloses the map area

Answer

A neatline is the border that frames the map, separating the map image from surrounding marginalia such as the legend and title.

Question 5

Which technique places labels along roads and rivers so that the text follows the feature's curve?

Accepted Answer

Curved label placement

Answer

Curved (or splined) label placement orients text along the path of linear features like rivers and roads to improve readability.
