3. 22. Potential of Hyperion imagery for simulation of MODIS NDVI and AVHRR-consistent NDVI time series in a semi-arid region

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Masoumeh Ghadiri; [2010]
   Keywords : Hyperion; NDVI; AVHRR; MODIS; time series; MODO; Earth and Environmental Sciences;

   Abstract : Long time series of satellite remotely sensed Normalized Difference Vegetation Index (NDVI) as an indicator of vegetation greenness can be used in a broad range of research topics such as climate change, vegetation dynamics and desertification monitoring. The first phase of this study tests a practical method using Hyperion imagery onboard on Earth Observing-1 (EO1) spacecraft for simulation of MODerate resolution Imaging Spectroradiometer (MODIS) NDVI and prediction of Advanced Very High Resolution Radiometer (AVHRR) NDVI data series in a semi-arid region in New Mexico, USA in 2007.

6. 25. Remote Sensing for Agricultural Land Use Changes and Sustainability Monitoring in Sudan

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Emmanuel Gbenga Olagunju; [2008]
   Keywords : Agriculture; GDP; irrigation; population remote sensing; sustainable development; GIS; NDVI; environmental sustainability and biodiversity;

   Abstract : The remote sensing technology is increasingly being used to study land use and vegetation cover changes and identify changes that has occur through different land use activities which may have negative impact on the sustainability of the environment, biodiversity protection and conservation. With increase in population growth rate in Sudan, there has been an increase for food crop production with agriculture playing a prominent role in livelihood security for the increasing population.
