`cellID`	Vector of grid cell IDs.
`featureMeasure`	Vector of grid cell sf feature lengths for linestring objects or sf feature areas for polygon objects.
`featureID`	Vector of grid cell sf feature IDs.
`mdm`	Vector of multidensity multipliers for the shapefile features.
`id`	Vector of sf feature IDs.
