Spatial evidence dataset for connecting fragmented urban voids in Oudlajan, Tehran

This dataset supports the article “From a single plaza to a public-space network: A design study of fragmented urban voids in Oudlajan, Tehran.” It contains machine-readable documentation of the evidence sources, spatial classification rules, approximate aggregate area values, comparison of two urban-design strategies, and the evidence-to-design decision matrix used in the study. Field documentation was produced between 2022 and 2025, with article-level design review in 2026. Questionnaire data, human-participant records, identifiable photographs, Google imagery, and Tehran Municipality cartographic material are not included. The reported areas are analytical estimates rather than cadastral measurements, and the proposal remains unbuilt.
