Improving Accuracy in Geospatial Information Transfer: A Population Density-Based Approach

The R package sc2sc offers fundamental tools for transferring information between census sections and postal codes in Spain, based on the cartography of these geographic segmentations. However, certain aspects for improvement have been identified. This document presents a substantial improvement to the package, optimizing the cp2sc function, which facilitates the transfer of information from postal codes to census sections. The introduced improvement considers population density as a corrective factor in the process, resulting in a more accurate and relevant data allocation. Various use cases highlight the improvement of the new methodology, though they also underline the need to work with updated and precise cartography, opening new lines of research and future work.
