Dasymetric analysis
WebDasymetric-Mapping Approaches An essential step in dasymetric mapping is the creation of zones within the areal unit that correspond to the variable being mapped. WebAlthough the dasymetric approach does not result in a more accurate risk analysis, the better geospatial visualization of risk in relation to the actual population location makes it possible to study the spatial clusters of morbidity and mortality within the geographic context of their occurrence.
