The objectives of the study are (1) to examine the effects of land cover type, green biomass, and solar zenith angle (SZA) on the bidirectional reflectance distributions (BRDs) of the visible and near-infrared advanced very high resolution radiometer (AVHRR) data from NOAA 11 over terrestrial surfaces; and (2) to correct for these effects by developing BRD functions (BRDF). Four land cover type...

Changes in land cover have become key components of global environmental change and represent the impact of human activity. To better understand the fundamental processes of land transition characteristics before and after the implementation of ecological programmes, we determined the dominant systematic changes in land cover in Yongshou, a hilly-gully region on the Loess Plateau. This was achi...

forest ecosystems that have spent a long time to mature, offer important goods and services to humanity. hence, utilization and exploitation of these resources should be based on careful assessment of their ecological value and potential. ecological land evaluation is an approach based on land quality, vulnerability and potential assessment for different acceptable uses drawing upon related mod...

This study explored the land use cover (LULC) change over 45 years (1975 -2020) in world’s largest mangrove forest, Sundarbansusing Landsat imagery. LULC maps were created with same-season imagery lowest cloud at four intervals: 1975, 1990, 2005, and 2020. Maximum likelihood classification (MLC) was applied to assign five classes: dense moderate sparse barren land, water body. Accuracy assessme...

Environmental issues like deforestation, biodiversity loss, soil erosion, siltation, wetland shrinkage, river bank etc. in drainage basin perspectives today are a rapid flux triggered by population growth and developmental activities. Focusing on the Lower Digaru River of North-East India,the present study investigates changes theLand Use / Land Cover (LULC)trend using geospatial techniques cau...

degradation of zagros forests has been continuing since a long time ago because of traditional and often improper exploitations due to poverty, unemployment, and livelihood. in this study, in order to reduce forest degradation and improve sustainability, the feasibility of multipurpose using of zagros forest was assessed in baneh forests by using gis, rs and ahp. all of the possible land-uses a...
