Disaggregating Population Data and Evaluating the Accuracy of Modeled High-Resolution Population Distribution—The Case Study of Germany

Sebastian Eichhorn
2020 Sustainability  
The article presents a dasymetric-based approach for modeling high-resolution population data based on urban density, dispersion, and land cover/use.  ...  With data on urban density, a relative deviation between the modeled and actual population of 14.1% is achieved. Data on land cover/use reduces the deviation to 12.4%.  ...  Author Contributions: S.E. is the sole author and responsible for all sections of the article. All authors have read and agreed to the published version of the manuscript.  ...

Unmixing Aggregate Data: Estimating the Social Composition of Enumeration Districts

R Mitchell, D Martin, G M Foody
1998 Environment and planning A  
An approach to 'unmixing' aggregate data, and thus to revealing the nature of the subunit variation masked by aggregation, is introduced.  ...  In this paper the authors address the problem of interpreting and classifying aggregate data sources and draw parallels between tasks commonly encountered in image processing and census analysis.  ...  SAS-like data are then derived from these synthetic ED populations and used to train an ANN to model the proportional presence of each household group.  ...
