This data set contains coordinate records of alien species populations worldwide. The data set was produced by applying the DASCO workflow (https://doi.org/10.5281/zenodo.5841930) using the SInAS database (version 2.4.1; https://doi.org/10.5281/zenodo.5562892). The workflow imports checklists of alien species such as those stored in SInAS, and extracts coordinates for the alien regions from GBIF and OBIS. After cleaning and thinning, the workflow exports a list of coordinates of alien populations. These files are part of a manuscript published in the journal Neobiota, where the workflow is described in detail (Seebens & Kaplan 2022, in press). The occurrence records are stored for GBIF and OBIS records in separate files. Files with "Coords" in file name contain coordinate records, while files with "regions" contain lists of alien species per region (mostly countries). The file DASCO_AlienRegions_SInAS_2.4.1.csv contains regional checklists for both GBIF and OBIS combined.
