ComputePolylineFeatureFromImage otbcli_ComputePolylineFeatureFromImage Compute Polyline Feature From Image Feature Extraction This application compute for each studied polyline, contained in the input VectorData, the chosen descriptors. ParameterRaster in Input Image An image to compute the descriptors on. False ParameterVector vd Vector Data Vector data containing the polylines where the features will be computed. False ParameterNumber elev.default Default elevation This parameter allows setting the default height above ellipsoid when there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles, and no geoid file has been set. This is also used by some application as an average elevation value. 0 False ParameterString expr Feature expression The feature formula (b1 < 0.3) where b1 is the standard name of input image first band False ParameterString field Feature name The field name corresponding to the feature codename (NONDVI, ROADSA...) False OutputVector out Output Vector Data The output vector data containing polylines with a new field
