Spatio-temporal Distribution of Wildfire Occurrences on the Lake Floor of Lake Chad Based on Remotely Sensed Data
Abstract: Normal 0 false false false EN-US X-NONE X-NONE This paper analyzes the spatio-temporal distribution of wildfire occurrences on the lake floor of the Lake Chad using satellite remote sensing data. A combination of field survey and computation of fire pixel counts from MODIS images for the period 2001–2009 form the basis for this analysis. The result revealed that the highest number of fires occurred in 2001, with varying figures in …

Analysis of Wildfire Occurrences within the Shores of Lake Chad using Geo-information Technology
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Geographic Information Technology provides an important tool in modeling ecosystem dynamics. One of the drivers of ecosystem change in the Lake Chad Basin is wildfire. This paper examines the historical spatial patterns of wildfires and employed a trend analysis using Geographic Information System (GIS) technique in analyzing fire pixel counts from MODIS images of the period 2001-2009. The results revealed a …

Monitoring Recent Vegetation Greenness Trend Impacted from Past Drought Events in Northern Arizona with AVIRIS and MODIS
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Northern Arizona has experienced a severe drought with significant impacts on various ecosystems. There have been extensive mortality and bark beetle insect population in conjunction with the multi-year drought. We evaluated remotely-sensed drought indicator with Airborne Visible Infra-Red Imaging Spectrometer (AVIRIS) hyperspectral data flown across the C. Hart Merriam Transect in northern Arizona and MODIS multispectral sensor. Drought impacts on vegetation …
