Integrated environmental assessment, risk mapping, and digital passportization of rocket stage fall zones

This paper presents an integrated approach to environmental assessment, risk mapping, and digital passportization of rocket stage fall zones using a geospatial platform based on Post GIS. The platform supports environmental data collection, storage, validation, analysis, and visualization, including geo referencing, data integrity control, pollutant normalization, calculation of integrated indicators, spatial analysis, and hotspot detection. An integrated environmental index (ERI) was developed using component-specific pollution indices, environmental hazard weights, a spatial impact factor, and data quality. The calculated ERI values ranged from 0.428 to 1.467, with Zone C showing the lowest impact and Zone D the highest environmental risk. Zones A, B, and E were classified as having a moderate impact level. The results showed that the soil component makes the largest contribution to the baseline environmental index (67.8–72.0%), followed by water (19.2–22.7%) and air (7.1–9.6%). Spatial analysis identified hotspot areas from 3.2 to 18.4 ha, with Zone D Assigned Priority I for monitoring and Zone C Priority IV. The data quality coefficient remained high in all zones (0.91–0.97), confirming the reliability of the proposed method. Overall, the approach enables reproducible environmental assessment, hotspot identification, and the creation of digital environmental passports for monitoring and decision support.
