Short Note on Land Use or Land Cover

Niharika Dvivedi*

The human activity related with a particular piece of land comes under land use. Land cover is associated to the type of feature present on the earth surface. The regions covered by forests, wetlands, impervious surfaces, agriculture, water types etc comes under land cover.by analysing satellite and aerial imagery we can determine land cover whereas land use cannot be determined from satellite imagery. Land cover information is used by the managers for better understanding of the present landscapes. There are two methods for collecting information on land covers. They are field survey and remotely sensed imagery analysis. Land change models can be built from these data to assess future shifts in land cover
