Surface covered by a LAS* object. For LAS point clouds it is computed based on the
convex hull of the points. For a LAScatalog it is computed as the sum of the bounding boxes
of the files. For overlapping tiles the value may be larger than the total covered area because
some regions are sampled twice.
