What is a Contour Map?

A contour map is a type of map that represents the elevation and shape of the land surface using contour lines. Contour lines are lines drawn on the map that connect points of equal elevation. These lines create a visual representation of the terrain’s topography, allowing for a better understanding of the land’s shape, slopes, and elevation changes.

Key features and uses of contour maps:

Contour maps are typically created using surveying techniques that involve measuring elevation at various points across the land. With the advancement of technology, including aerial LiDAR (Light Detection and Ranging) and satellite imagery, accurate and detailed contour maps can be generated. These maps serve as valuable tools for underground utility planning, design, and environmental analysis, enabling engineers and planners to make informed decisions and ensure the efficient and sustainable development of utility systems.
