Disaggregator – a tool for the aggregation and disaggregation of spatial data

This paper describes the Disaggregator tool, developed for the aggregation and disaggregation of spatial data. There exist several types of point data that need to be aggregated for more effective visualization. On the other hand, some statistical datasets are only available for larger areas; the disaggregation procedure can recalculate this data into smaller areas. All disaggregation methods are strongly dependent on auxiliary data, so many disaggregation approaches, including dasymetric mapping, have been discussed in the literature. At the same time, only a few software implementations exist. Their functionality is very limited (Intelligent Dasymetric Mapping Toolbox) or they use only one method (e.g. the areal interpolation method), or their development is no longer supported (QGIS Dasymetric plugin). Disaggregation methods involve a more complex procedure, which makes them harder to automate and program. Due to the lack of ready-to-use softwaresolutions, the Disaggregator tool for ArcGIS Pro was created and published on GitHub as freely available software. It offers several methods for aggregation and disaggregation of spatial data. The tool was tested on several statistical datasets in Czechia.
