Njintout landslide

Sentinel-1 SBAS-InSAR processed outputs supporting the study of pre-failure ground motion at the 19 September 2025 Njintout landslide, Foumban district, Central Cameroon Volcanic Line. Derived from 29 Sentinel-1A ascending-track (relative orbit 59) acquisitions spanning 30 June 2024 to 23 October 2025, processed with PyGMTSAR (Goldstein filter pass) and small-baseline (SBAS) time-series inversion. Contents: (1) three geocoded LOS velocity rasters (linear-fit mm/year, linear-fit mm/month, and STL-decomposed mm/year; EPSG:4326, ~50 m pixel spacing, 819×845); (2) a 29-epoch LOS displacement time series (NetCDF, same grid); (3) a GeoJSON point layer of per-pixel LOS velocity and R² for a subsampled high-quality cell set; and (4) an interactive Leaflet/Folium HTML map of the velocity field. All products cover the ~880 km² Foumban administrative-boundary AOI (10.7235–11.0144°E, 5.5672–5.8676°N) and the documented Njintout failure point (10.8897°E, 5.7330°N).
