Coordinate Subscidence Mapping

This upload includes the two core geospatial input datasets used to generate all hotspot-based environmental metrics in the study “Detecting and Characterizing Land Subsidence Hotspots using Multi-Source Earth Observation Data (2000–2024)”. These files are critical for producing the reproducible outputs published in the accompanying GitHub repository. EGMS_L3_E36N32_100km_U_2019_2023_1.zipThis file contains vertical displacement velocity measurements from the European Ground Motion Service (EGMS), Level 3, Unwrapped (U) product. It covers a 100 km × 100 km tile (E36N32) for the period 2019–2023. The dataset includes persistent scatterer interferometry (PSI) point locations and average velocity values (mm/year), which are used to detect subsidence clusters and generate the base hotspot grid. oproad_gpkg_gb.zipThis archive includes the full national OpenRoads GPKG dataset for Great Britain, obtained from the Ordnance Survey. The dataset is used to identify road segments that intersect subsiding regions by performing spatial overlay with buffered hotspot zones. Both datasets are used as inputs to the reproducible pipeline available at https://github.com/thalosang77/corine-hotspot-analysis. All other datasets referenced in the study (e.g., MODIS, CORINE, Sentinel-2, TerraClimate) are accessed dynamically via the Google Earth Engine API and do not require local hosting. The uploaded files are provided in their original form to ensure data integrity and compatibility with the processing scripts.
