WZONE is a dataset of conflict zones. The conflict zones are created from the UCDPGED event data (version 24.1) with a machine learning method, so-called a one-class support vector machine, which is detailed <a href="https://doi.org/10.1017/psrm.2020.16">here</a>. The technical details, such as hyper-parameter selection, are also detailed in the <a href="https://static.cambridge.org/content/id/urn:cambridge.org:id:article:S2049847020000163/resource/name/S2049847020000163sup001.pdf">appendix</a> of the article. The dataset is available in the ESRI Shapefile format for each conflict dyad at a daily level. A Youtube video is also available at <a href="https://youtu.be/1pQx8_EjxmA">here</a>.<br/ ><br/ >

There is a separate zip file for each year (1989-2023). Each zip file contains shape files (365 or 366 files; daily). The shape files have three columns; "dyad_id" (new dyad IDs in the UCDPGED), "conf_id" (new conflict IDs in the UCDPGED) and "date" (date of the conflict zone). The static.zip contains time-invariant estimates of conflict zones and their lower and upper confidence intervals. Finally, ged_summary.csv provides basic information of each conflict dyad, which can be merged to the conflict zone data by using dyad_id variable. For details of the variables in the summary data, refer to <a href="http://ucdp.uu.se/downloads/ged/ged241.pdf">the codebook of the UCDPGED</a>.
