“Combining Areal & Point Data in Geostatistics Interpolation:
Applications to Soil Science & Medical Geography”
A common issue in spatial interpolation is the combination of data measured over different spatial supports. For example, in the field of medical geography information available for mapping disease risk typically includes point data (e.g. patients residence) and aggregated data (e.g. socio-demographic and economic data at the census track level). Similarly, soil measurements recorded at discrete locations on the ground are often supplemented with choropleth maps (e.g. soil or geological maps) that model the spatial distribution of soil attributes as the juxtaposition of polygons (areas) with constant values. This lecture presents a coherent geostatistical approach to accommodate both areal and point data in the spatial interpolation of continuous attributes, with applications to soil science and medical geography.
Pierre Goovaerts was invited with the support of the IAMG Lisbon Student Chapter.
