Using Satellite Remote Sensing and Geographic Information System, this paper analyzes the land use and land cover change dynamics in the Bosomtwe District of Ghana, for 1986, 2010 thematic mapper and enhanced thematic Mapper+ (TM/ETM+) images, and 2014 Landsat 8 Operational Land Imager and Thermal Infrared Sensor (OLI/TIS) image. The three images were geo-referenced and processed for classifica...

The construction of the Belo Monte hydroelectric dam began in 2011, resulting in rapidly increased population from less than 80,000 persons before 2010 to more than 150,000 persons in 2012 in Altamira, Pará State, Brazil. This rapid urbanization has produced many problems in urban planning and management, as well as challenging environmental conditions, requiring monitoring of urban land-cover ...

Wyoming's Green Mountain Common Allotment is public land providing livestock forage, wildlife habitat, and unfenced solitude, amid other ecological services. It is also the center of ongoing debate over USDI Bureau of Land Management's (BLM) adjudication of land uses. Monitoring resource use is a BLM responsibility, but conventional monitoring is inadequate for the vast areas encompassed in thi...

Mountainous regions are especially vulnerable to climate and land use change. For a monitoring of subtle changes detailed and continuous land cover information is necessary. Therefore vegetation cover fractions are derived for the Naryn river catchment in Kyrgyzstan using a remote sensing multi-scale approach. First a very high resolution QuickBird image is classified into discrete classes usin...

Tidal flat, a transition zone between the ocean and land, forms a unique ecosystem, providing the habitat for various specious of fauna and flora, which is very important in purifying pollutants discharged from land and in providing marine products such as oysters and many kinds of shellfishes [1]. Thus, monitoring and mapping of tidal flat is urgently needed for sustainable managements and the...

Within a military land activity context, relationships between stream water chemistry and watershed land use, topography and vegetation were explored at the Fort Benning Military Installation, Georgia. Water quality parameters, including pH, temperature, conductivity, total Kjeldahl nitrogen, total phosphorus, total organic carbon, chloride, and total suspended solids, were routinely measured i...

Analysis of the full waveform return pulse of laser altimeter systems is expected to increase the possibilities and accuracy in well-known applications of laser altimetry like DTM generation, forestry and earth surface analysis. NASA’s ICESat Geoscience Laser Altimeter System (GLAS) was launched in 2003 and acquires full waveform data along profiles covering the entire earth. In this study, the...

The biophysical environment is an important determinant of land degradation in both commercial and communal land tenure systems in South Africa. According to a recent study on the status of land degradation, approximately 25% of the total land cover in South Africa is degraded. Several technologies exist to restore the soil and vegetation degraded areas in natural pastures. To improve the produ...
