Grass_Raster_CurvatureService

Operation:

tangential_curvature - Generates raster map layer of tangential curvature from a raster map layer of true elevation values. Tangential curvatures are the curvatures in the direction of the contour tangent. The curvatures are expressed as 1/metres. The operation is based on GRASS raster command r.slope.aspect.

Request Parameters:

sourceURL
URL of input raster elevation file
Default format: GeoTIFF
zfactor
Multiplicative factor to convert elevation units to meters
Parameter format: float
Default: 1.0
outputGeoTiffType
Type of output GeoTIFF file. The output Format Type is specified as GeoTIFF
Parameter format: string
Options: Byte, Int16, UInt16, UInt32, Int32, Float32, Float64, CInt16, CInt32, CFloat32, CFloat64

Response Parameters:

returnURL
URL of output tangential curvature file
returnFormat
Format of output tangential curvature file
Default: GeoTIFF
