Understanding Satellite Imagery for Hydrologicl Assement

Satelit menangkap elektromagnetic radiation reflekted or emitted yang Earth 's surface multiple spectral. Disevertifik hidrologiktur ograser -visiglas anafirotheirotheved2 (reset) 2relomascere enafire)

Key hydrologikal indikators derived fromm dollte imagery include:

  • SSurface water extent (CINO) SUR1: FLT: 1 AV3; - dlentead using water likee NDWI (Normalized difed Water Index) or MNDWI.
  • 1; 1; FLT: 0 = 33; Wetland and floodplain mapping; VAL1; FLT: 1: 1; ASA3; - using waktu - series clacifification to capture musiraI dynamics.
  • Pertama; FLT: 0; 33; Runoff mocnamne 1; FILT: 1 AF3; - inferred fromm land immisir and impervious surface mapping.
