CGIS invites you to a research seminar taking place on 17 May 2012, 12:30-13:30 in the Geography building, room 1-2. Philemon Tsela and Abiodum Adeola will be presenting on their research.
Title: Evaluation of the MODIS satellite burned area products across four-fire prone biomes in South Africa
Biomass burning in South Africa is one of the main drivers of land cover changes and climate variability, which currently is a hot topic in the scientific community. The monitoring and mapping of burned areas therefore affords the remote sensing community an opportunity to investigate the impacts of fires on the ecosystem dynamics. My current research focuses on investigating the accuracy of the official Global Moderate Resolution Spectroradiometer (MODIS) satellite burned area products called the MCD45A1 and MCD64A1.
These two products are derived from MODIS land surface reflectance data using algorithms that follow different mathematical principles. During the presentation, the different burned area products across four-fire prone biomes (encompassing savanna, grassland, fynbos and exotic pine forest) in South Africa will be compared and results discussed.
Title: Development of a malaria early warning system using GIS and remote sensing
At present controlling Malaria in South Africa is based on both preventing infections and on prompt effective treatment of clinical cases. Through the National Malaria Strategic Plan, the Malaria and parasitic disease control unit supports Malaria prevention and treatment services across the Malaria prone areas of South Africa. Predicting the abundance, as well as understanding the risk factors, spatial distribution, and spread of Malaria in endemic settings can significantly contribute to local Malaria control strategies. A deeper understanding of the role of landscape attributes in the spatial distribution of Malaria is crucial so that appropriate local elimination efforts can be developed. The presentation focuses on identifying various data resources as well as formulating a robust warming system needed for the effective dissemination of information on climate change, ecosystem services and human health using Geographic Information System and Remote Sensing in South Africa.
