Long Description
The first step in the classifier fusion based validation is to compute, for each studied polyline, the chosen descriptors.
Parameters
[param] -in <string> An image to compute the descriptors on.. Mandatory: True. Default Value: ""
[param] -vd <string> Vector data containing the polylines where the features will be computed.. Mandatory: True. Default Value: ""
[param] -elev <string> This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff processed by the DEM import application. Mandatory: True. Default Value: "0"
[param] -expr <string> The feature formula (b1 < 0.3) where b1 is the standard name of input image first band. Mandatory: True. Default Value: ""
[param] -field <string> The field name corresponding to the feature codename (NONDVI, ROADSA...). Mandatory: True. Default Value: ""
[param] -out <string> The output vector data containing polylines with a new field. Mandatory: True. Default Value: ""
Limitations
Since it does not rely on streaming process, take care of the size of input image before launching application.
