11. The potential of support vector machine classification of land use and land cover using seasonality from MODIS satellite data
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : With respect to climate change it is necessary to study land use and land cover (LULC) and their changes. LULC are related directly and indirectly to climatic changes such as rising temperatures that trigger earlier onset of vegetation growing seasons (IPCC 2007). LÄS MER
12. Climate variability and satellite : observed vegetation responses in Tanzania
Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Climate and vegetation growth of an area are interrelated processes; both take place on small to global scales. However, climate change and variability impacts on vegetation in most places in the world including Tanzania is of great concern since vegetation supports many socio-economic sectors, and plays a crucial role in atmospheric greenhouse gas moderation.

13. Potential of Hyperion imagery for simulation of MODIS NDVI and AVHRR-consistent NDVI time series in a semi-arid region
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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.

14. Empiriska samband mellan fältdata och satellitdata för olika bokskogsområden i södra Sverige
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Populärvetenskaplig sammanfattning: Målet med studien är att se vilka samband som finns mellan insamlad fältdata och beräknad satellitdata för bokskogsbestånd i södra Sverige (Häckeberga naturreservat och naturområde). Fältdata som använts består av uppskattat bladyteindex, beräknad biomassa samt kategoriserade åldersgrupper av 19 provytor bokskog (Fagus Sylvatica), indelat i tre grupper. LÄS MER
15. Investigating vegetation changes in the African Sahel 1982-2002 : a comparative analysis using Landsat, MODIS and AVHRR remote sensing data
Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : There has been much debate concerning the concept of degradation and desertification in semi-arid lands, in particular semi-arid Sub-Saharan Africa, during the last two decades. However, recent findings suggest a consistent trend of increasing satellite-derived vegetation greenness in much of the African Sahel as interpreted from Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data for the period 1982-1999.
