Knowledge about the land cover of large areas is important for monitoring and modeling of ecological and environmental processes and for land cover change detection. Considerable efforts have recently resulted in the development of global continuous fields for different land cover types at large spatial scales based on NOAA-AVHRR, SPOT-VEGETATION, and TERRA-MODIS data. Researchers have applied ...
Land cover change associated to urbanization processes represents one of the most insidious forms of ecosystem alteration and links frequently to other types of environmental degradation. Timely and accurate remotely sensed detection of land cover change is therefore an essential requirement for a better understanding of coupled natural and human systems in urban expansion areas. Landscape dyna...
Land-cover and climate change are both expected to alter species distributions and contribute to future biodiversity loss. However, the combined effects of land-cover and climate change on assemblages, especially at the landscape scale, remain understudied. Lowland tropical amphibians may be particularly susceptible to changes in land cover and climate warming because many species have narrow t...
[1] This paper presents an ARTMAP neural network approach for burn detection in Moderate Resolution Imaging Spectroradiometer (MODIS) data using two methods: discrete and continuous classifications. The study area covers the states of Idaho and Montana in the United States, where extensive fire events took place during the months of July and August in the year 2000. The proposed approach differ...
Remote sensing and gis-based Land use and land cover change detection in the upper Dijo river catchment, Silte zone, southern Ethiopia Working papers on population and land use change in central Ethiopia, nr. 17 ABSTRACT Land use and land cover (LULC) change is one of the challenges which strongly influence the process of agricultural development and the food security situation in Ethiopia in g...
To investigate land use changes, Qale Shahrokh basin (15098.1 ha area) was selected. Satellite images of Landsat sensors (MSS, TM and ETM+) were used. After improvement and different enhancement analysis of images such as FCC, PCA, the study area was checked using GPS and topographic maps (1:50000) and other information. Land use units were determined using classified random sampling method. Ma...
The main objective of this study is to assess the spatio-temporal dynamics of land cover/land use changes in the lower Mekong Delta over the last 40 years with the coastal Tran Van Thoi District of Ca Mau Province, Vietnam as a case study. Land cover/land use change dynamics are derived from moderate to high spatial resolution (Landsat and SPOT) satellite imagery in six time intervals ranging f...
