QGIS Algorithm provided by QGIS (native c++) Line density (native:linedensity). The line density interpolation algorithm calculates a density measure of linear features which is obtained in a circular neighborhood within each raster cell. First, the length of the segment of each line that is intersected by the circular neighborhood is multiplied with the lines weight factor. In a second step, all length values are summed and divided by the area of the circular neighborhood. This process is repeated for all raster cells.

further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
