Sentinel-2 Spectral Indices
Vegetation, water, built-up and alteration minerals from real imagery.
Finds Sentinel-2 Level-2A scenes over your area, renders spectral indices such as NDVI, NDWI, NDBI, NBR and the clay, ferrous and iron-oxide mineral ratios as map layers, computes area statistics, and compares two dates to measure change.
Overview
Imagery is served by the Microsoft Planetary Computer, which hosts the full Sentinel-2 archive as cloud-optimised files. Choose a date range and cloud limit, pick a scene, and switch between indices and colour composites. Area statistics return the mean, spread and histogram of the index inside your rectangle.
Change mode places a baseline scene beside a recent one and reports the difference in each index, for desertification, wetland loss or urban growth studies.
