Description

To subdivide barren lands in urban and urbanization areas and clarify their distribution, the algorithm for land use and land cover including subdivisions of barren lands in greater Sapporo area was developed using satellite data. Two types of natural barren lands and one of artificial barren lands were designated from NDVI and NDVI Range, and another artificial one with spectrum pattern similar to upland fields was designated by non-statistical processing. From the land use map including four types of barren lands, it was clarified that artificial barren lands were larger than natural barren lands in municipalities with newly-reclamated industrial complex.
