The continuous extraction of wood and the conversion of forest to small- and large-scale agricultural parcels is rapidly changing the land cover of the mount Cameroon region. The changes occur at varying spatial scales most often not more than 2ha for the small-scale subsistence farms and above 10ha for the extensive agricultural plantations of cocoa and palm. Given the importance of land use a...

One of the most prominent tourist destinations in Adriatic coast, city Opatija, is facing a problem concerning seasonal drinking water shortages. The existing resources are no longer sufficient, and attention being given to alternative such as underlying karstic aquifer several coastal springs itself. However, potential area still cannot be estimated due insufficient hydrological data. goal thi...

In this paper, urban growth of Bangalore region is analyzed and discussed by using multi-temporal and multi-spectral Landsat satellite images. Urban growth analysis helps in understanding the change detection of Bangalore region. The change detection is studied over a period of 39 years and the region of interest covers an area of 2182 km 2 . The main cause for urban growth is the increase in p...

To facilitate the identification of appropriate post-fire watershed treatments and minimize erosion effects after socio-economically important fires, Interagency Burned Area Emergency Rehabilitation (BAER) teams produce initial timely estimates of the fire perimeter and classifications of burn severity, forest mortality, and vegetation mortality. Accurate, cost-effective, and minimal time-consu...

[1] Satellite-based triangle models for evapotranspiration estimation are unique in interpreting the relationship between the normalized difference vegetation index (NDVI)/ factional vegetation cover (fc) and surface radiative temperature (Trad) across large heterogeneous areas. However, output and performance of triangle models may depend on the size of the domain being studied and resolution ...

Remote sensing can be understood as the science, technology and art of acquiring, processing, and interpreting airborne or spaceborne images that record the interaction between matter and electromagnetic energy (Sabins, 1997, Aranoff, 2005). Nowadays a plethora of satellites surrounding the earth provides continuous sets of data of quite different nature used for navigation, positioning, meteor...

The aim of the study is to assess the limestone (LS) exploitation area and its negative impacts on natural resources using geo-spatial techniques. LS is an important constituent of cement manufacturing which is extensively used in the construction of infrastructure such as roads and buildings. The Margalla Hills National Park (MHNP) is situated around Islamabad and contains a large amount of LS...

Vegetation responses and ecosystem function are spatially variable and influenced by climate variability. The Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) was used to combine MODIS (Moderate Resolution Imaging Spectrometer) and Landsat TM/ETM+ (Thematic Mapper/ Enhanced Thematic Mapper plus) imagery for an 8 year dataset (2000-2007) at 30m spatial resolution with 8 day interv...

The importance of accurately monitoring rangeland degradation dynamics over decades is increasing in Linxia rangeland, the birthplace of the Yellow River in China. Since 2000, the Chinese government has implemented the “Grain for Green” program and enforced a grazing ban in Gansu province, one of the most degraded provinces, to mitigate the problem of rangeland degradation. The effects of these...

Coal fires are a common and serious problem in most coal-bearing countries. Thus, it is very important to monitor changes in coal fires. Remote sensing provides a useful technique for investigating coal fields at a large scale and for detecting coal fires. In this OPEN ACCESS Remote Sens. 2015, 7 3089 study, the spreading direction of a coal fire in the Wuda Coal Field (WCF), northwest China, w...
