Definition

Terrain is the vertical and horizontal dimensions of a landscape and slope describes the change in elevation over a distance in some direction.

Introduction

The effect of slope and terrain on wildfires and wildland urban interface (WUI) fires is multifaceted. Wildfire occurs in a physical space and must obey physical laws pertaining to a combination of weather, fuel, and topography (Countryman 1972). Topography refers to the arrangement of natural and artificial features of the landscape. Slope and terrain are elements of topography.

Measuring Slope and Terrain

The term terrain describes a landscape surface horizontally and vertically. Typically, the vertical component of terrain is called elevation. Elevation is a height with respect to mean sea level or a mathematical surface (datum) that estimates the mean sea level. Measuring elevation can be done manually using land surveying techniques to achieve submillimeter accuracy or...
