Field Coding Dataset and Analytical Decision Matrix for Interstitial Urban Voids Study

This dataset contains the Excel-based field coding form, coding dictionary, final void-type assignment, analytical decision matrix, intervention-threshold categories, reliability and reflexivity documentation, and summary counts used for the on-site documentation and typological analysis of interstitial urban voids. Version 3 expands the methodological documentation and analytical audit trail by providing detailed operational coding anchors, examples and ambiguity rules, strengthened reliability and reflexivity notes, and updated methodological safeguards aligned with the revised manuscript. The underlying 61 field records and final typology counts remain unchanged.
