Optimised Pattern Size for land cover-land use information conversion

Abstract

Can we keep a lonely tree in the middle of a plowed parcel to be a forest? Or a glade, opening in the place of a fallen tree, to be a meadow? Surely not. In this case emerges the question, where starts the forest, and where the meadow? OPS (Optimised Pattern Size) represents the unit size of a land cover, with which it can be mapped optimally, based on the classification of MS VHR satellite images. By the described case study, I demonstrate the OPS computation method, which can be totally automated and integrated into recent classification programs, in order to reduce land cover-land use conversion problem onto the level of semantics, and to let regional and local authorities to be supplied with timely land use information.
