Improving Large Area Population Mapping Using Geotweet Densities

Many different methods are used to disaggregate census data and predict population densities to construct finer scale, gridded population data sets. These methods often involve a range of high resolution geospatial covariate datasets on aspects such as urban areas, infrastructure, land cover and topography; such covariates, however, are not directly indicative of the presence of people. Here we...

Risk Mapping of Anopheles gambiae s.l. Densities Using Remotely-Sensed Environmental and Meteorological Data in an Urban Area: Dakar, Senegal

INTRODUCTION High malaria transmission heterogeneity in an urban environment is basically due to the complex distribution of Anopheles larval habitats, sources of vectors. Understanding 1) the meteorological and ecological factors associated with differential larvae spatio-temporal distribution and 2) the vectors dynamic, both may lead to improving malaria control measures with remote sensing a...

Mapping parcel-level urban areas for a large geographical area

As a vital indicator for measuring urban development, urban areas are expected to be identified explicitly and conveniently with widely available dataset thereby benefiting the planning decisions and relevant urban studies. Existing approaches to identify urban areas normally based on midresolution sensing dataset, socioeconomic information (e.g. population density) generally associate with low...

Comparison of Dasymetric Mapping Techniques for Small-Area Population Estimates

Dasymetric mapping techniques can be employed to estimate population characteristics of small areas that do not correspond to census enumeration areas. Land cover has been the most widely used source of ancillary data in dasymetric mapping. The current research examines the performance of alternative sources of ancillary data, including imperviousness, road networks, and nighttime lights. Natio...

Fast Mapping Of Biological Samples With Large Area EDS Detectors

Energy Dispersive Spectroscopy (EDS) has been used for many years to analyse the chemical composition of materials, including biological matter. However, the physical limitations of often being able to use only low beam currents, low accelerating voltages and only generating very low X-Ray count rates on a sample mainly comprised of light elements meant that until now, biological EDS has been s...
