Definition

1. Noun:
   • A map that uses contour lines to show elevation: A "relief map" is a two-dimensional representation of terrain where lines connect points of equal height above a given level, such as sea level. This allows the viewer to understand the three-dimensional shape of the land, including hills, valleys, and slopes.

Usage

• The primary use of a "relief map" is in geography, cartography, geology, and outdoor activities like hiking. It is a tool for visualizing topography.
• It is typically used as a countable noun (e.g., , ).

Examples

• Noun:
  • The hikers studied the relief map to understand the steepness of the trail ahead.
  • This relief map clearly shows the river valley and the surrounding plateau.
  • For his geography project, he created a detailed relief map of the local mountain range.

Advanced Usage

• "Shaded relief map": A map where contour lines are combined with simulated shading to create a more visually intuitive, three-dimensional appearance of the terrain.
  • The shaded relief map made it much easier to identify the mountain ridges.

Variants and Related Words

• Topographic map (n): A map that uses contour lines to represent the shape and elevation of the land surface. This is often synonymous with "relief map."
• Contour map (n): Another term for a map that uses contour lines, essentially identical to a relief map.
• Hypsometric map (n): A map that uses colors or tints between contour lines to indicate different elevation ranges.

Synonyms

• Topographic map
• Contour map

Related Phrases

• Relief model (n): A physical three-dimensional model of terrain, as opposed to a two-dimensional map. This is a different, though related, object.
  • The museum displayed a relief model of the canyon next to the relief map.

Noun

1. a map having contour lines through points of equal elevation
