SLOPE Siddharth Nagar


Slope can be defined as the angle, inclination, steepness, or gradient of a straight line.

Slope often is used to describe the steepness of the ground’s surface.

Slope can be measured as the rise (the increase in elevation in some unit of measure) over the run (the horizontal distance measured in the same units as the


Many geographic information systems (GIS) can analyze digital elevation data (elevation points, contour lines, digital elevation models, etc.) and derive both slope and aspect data sets.

The slope is the steepness or the degree of incline of a surface.

Slope can’t be computed from the lidar points directly; one must first create either a raster or TIN surface.

Then, the slope for a specific location is computed because of the maximum rate of change of elevation between that location and its surroundings.

The slope can be expressed either in degrees or as a percentage.
