A new method for determining the population with walking access to transit
The use of geographic information systems in determining transit service areas has not progressed far beyond simple buffering operations even though there is widespread capability to analyze network walking distances in conjunction with demographic, cadastral, and land-use data sets. This article presents a method for determining the population with walking… (More)
Assessing the methods needed for improved dengue mapping: a SWOT analysis
INTRODUCTION Dengue fever, a mosquito-borne viral infection, is a growing threat to human health in tropical and subtropical areas worldwide. There is a demand from public officials for maps that capture the current distribution of dengue and maps that analyze risk factors to predict the future burden of disease. METHODS To identify relevant articles, we… (More)
Mosquito habitat and dengue risk potential in Kenya: alternative methods to traditional risk mapping techniques.
Outbreaks, epidemics and endemic conditions make dengue a disease that has emerged as a major threat in tropical and sub-tropical countries over the past 30 years. Dengue fever creates a growing burden for public health systems and has the potential to affect over 40% of the world population. The problem being investigated is to identify the highest and… (More)
Risk analysis for dengue suitability in Africa using the ArcGIS predictive analysis tools (PA tools).
BACKGROUND Risk maps identifying suitable locations for infection transmission are important for public health planning. Data on dengue infection rates are not readily available in most places where the disease is known to occur. METHODS A newly available add-in to Esri's ArcGIS software package, the ArcGIS Predictive Analysis Toolset (PA Tools), was used… (More)
Combined approach of a couple fire model with atmospheric releases: the case of the 2003 Glacier wildfires
A combined GIS and remote sensing approach is applied to map and model the Glacier National Park wildfires of the summer 2003. Numerical simulations were performed using the Clarke Fire Automaton Model, and the fire extents were associated with the atmospheric plumes, observed using remote sensing data from the MODerate resolution Imaging Spectro-radiometer… (More)
Atmospheric releases during the 2003 glacier wildfires: Mapping, analysis and modeling
A combined GIS and remote sensing approach to map and model the large wildfires in the summer 2003 at Glacier National Park. Numerical simulations were performed using the Clarke cellular automaton fire model, and the fire extents were validated using remote sensing data from the MODIS instrument. The results show a good correlation between the predicted… (More)
