Vegetation index mapping

Derives vegetation health, density, and phenology indicators (NDVI, EVI, SAVI) from red and NIR band ratios; good for crop monitoring, deforestation alerts, and land cover change detection.

Band-ratio indices from red (~660 nm) and NIR (~840 nm). NDVI saturates in dense canopies; EVI corrects for atmosphere and soil background noise. Implemented across the entire Landsat/Sentinel-2/MODIS fleet. Wikipedia: Normalized difference vegetation index

Demonstrated
Capable, undemonstrated
  • CARMA Climate Risk Platform
  • MariMap

    MariMap satellite context includes spectral indicators relevant to seagrass and mangrove health, consistent with vegetation index mapping applied to coastal/marine shallow-water imagery.

  • OceanTech R&D

    OceanTech R&D uses spectral vegetation index products (seagrass extent, mangrove canopy) derived from Copernicus satellite imagery to track marine habitat extent and health.

  • VectorSurv Vectorborne Disease Surveillance System
  • CS-252 Suupistri

    CS-252 Suupistri visible-spectrum camera capable of vegetation index mapping from orbit

  • CS-292 Suupistri-EO

    CS-292 Suupistri-EO 350-850 nm spectral range covers red edge and NIR; capable of vegetation index mapping

  • PAIS Optical Payloadpending review
  • Valk VHRpending review
  • MX (Cartosat-3)

    MX includes red and near-infrared bands needed for standard vegetation-index mapping.

  • Pléiades Neo Imager

    The imager has red, red-edge and near-infrared channels suitable for vegetation-index mapping.

  • AEISS

    AEISS includes red and near-infrared multispectral bands suitable for vegetation-index mapping.

  • Coastal Zone Imager

    CZI 650 nm and 825 nm bands enable NDVI-equivalent vegetation index mapping over coastal zones and tidal flats

  • Retrieves chlorophyll-a concentration, CDOM, and suspended sediment from spectrally resolved water-leaving radiance; good for marine primary production, harmful algal bloom detection, and coastal water quality.

  • Images the sea surface in sun-glint geometry, where surface-slope modulation of reflected sunlight reveals wave patterns and roughness; supports wave-spectrum and roughness estimation under clear-sky, suitable-illumination conditions. A complementary optical method, not an all-weather baseline.

  • Measures calibrated night-time visible to near-infrared radiance from low-light imagers, supporting economic activity, electrification, outage, urbanisation, and light-pollution analyses.
