Ecologically oriented geoinformation support for urban spatial development considering emergency pollution sources (case study of the Southern sector of Moscow)

This paper presents the results of developing and testing a model for ecologically oriented geoinformation support for urban spatial development tasks. The relevance of the study stems from the need to implement modern sustainable urban planning requirements and integrate environmental requirements into territorial management systems during the transition to a “green” economy. The novelty of this work lies in the comprehensive consideration of not only stationary pollution sources but also emergency sources - road traffic accident (RTA) hotspots. The proposed model includes three interconnected layers: informational, legal, and organizational. Criteria for quantitative assessment of the level of environmental-legal provision of a territory (Kep) and an automated data verification method are developed. Testing was conducted on a pilot cluster bounded by Varshavskoe Highway, Kashirskoe Highway, and the Moscow Ring Road using open traffic accident data from 2021–2025. Model implementation increased environmental and territorial spatial data compatibility from 34% to 89%, reduced the share of plots with environmental-legal conflicts from 28% to 9%, and decreased conflict resolution time from 45 to 15 working days. The integral Kep indicator increased by 33.5% (from 0.573 to 0.765). The results can be used in creating environmentally oriented geoinformation systems at federal, regional, and municipal levels.
