Remote Sensing
-
Satellite image based remote sensing is widely applied in situations such as mineral mapping, disaster assessment, monitoring deforestation, urban monitoring, etc.
-
Can be recognized as a low cost approach to achieve above goals
-
RGB, Multispectral or Hyperspectral images are used
-
Multiple algorithms were published in Change Detection and Hyperspectral Unmixing
Land Cover & Mineral Mapping
Classification of land use (urban, forest, water) and identification of specific mineral deposits using hyperspectral data.
Environmental Risk Mitigation
Rapid disaster assessment and mapping of affected areas after floods, fires, or earthquakes to prioritize relief efforts.
Remote Surveying & Monitoring
High-accuracy monitoring of large infrastructure (roads, rail) and environmental assets (forests, waterways) to reduce manual survey costs
