This paper presents an extended multi-sensor geoinformation framework for monitoring forest ecosystems in Ukraine under conditions restricted field access. Building upon previously validated hexagonal GIS and NDVI-based remote sensing methodology applied to Zhytomyr Oblast (2021–2024), the current study incorporates an expanded Sentinel-2 time series through 2025 and introduces a theoretical framework for integrating Sentinel-1 Synthetic Aperture Radar (SAR) data to overcome the critical limitation of optical cl...
