Running CARS with DSM as input

CARS can also be launched with DSM as inputs. The standard pipeline launched is just a merging of the DSM.

However filling steps can also be performed after the merging if the needed information are given in the configuration file (classification and initial_elevation to fill the DSM, sensors to fill the ortho image)

Name	Description	Type	Default value	Required
dsm	List of DSM to merge	dict	No	Yes
roi	Region Of Interest: Vector file path or GeoJson dictionary	string or dict	None	No
initial_elevation	Low resolution DEM (used for DSM filling)	string or dict	No	No
sensors	Stereo sensor images used to generate the DSM	dict	No	No
pairing	Association of sensor images used to generate the DSM	list of pairs of sensors	No	No (*)

(*) pairing is required if sensors parameter is set and contains more than two sensors

For each DSM, give a particular name (what you want):

            }
        }
    }
}

These input files can be generated by running CARS with product_level: [“dsm”] and auxiliary dictionary filled with desired auxiliary files

Note

Only one method for performance map generation should have been selected: only two dimensions rasters for dsm_inf*.tif, dsm_sup*.tif, performance_map.tif are supported.
