xdem.terrain#
Terrain attribute calculations, such as slope, aspect, hillshade, curvature and ruggedness indexes.
Functions
|
Calculate the aspect of each cell in a DEM, returned in degrees by default. |
|
Calculate the terrain curvature (second derivative of elevation) in m-1 multiplied by 100. |
|
Calculates the fractal roughness, the local 3D fractal dimension. |
|
Computes quadric and other coefficients on a fixed 3x3 pixel window, and that depends on the resolution. |
|
Derive one or multiple terrain attributes from a DEM. |
|
Return terrain indexes based on a windowed calculation of variable size, independent of the resolution. |
|
Generate a hillshade from the given DEM. |
|
Calculate the signed maximum profile or planform curvature parallel to the direction of the slope in m-1 multiplied by 100. |
|
Calculate the terrain curvature perpendicular to the direction of the slope in m-1 multiplied by 100. |
|
Calculate the terrain curvature parallel to the direction of the slope in m-1 multiplied by 100. |
|
Calculates the roughness, the maximum difference between neighbouring pixels, for any window size. |
|
Calculates the rugosity, the ratio between real area and planimetric area. |
|
Generate a slope map for a DEM, returned in degrees by default. |
|
Calculates the Terrain Ruggedness Index, the cumulated differences to neighbouring pixels. |
|
Calculates the Topographic Position Index, the difference to the average of neighbouring pixels. |
