CBERS
CBERS constellation consists of four satellites: CBERS-1 and 2, CBERS-3 and 4. It brings significant value to monitoring water resources, agriculture, urban growth, and land use, with a large focus on controlling the deforestation and burning of the Amazon rainforest.
It has three imaging instruments on board: a high-resolution optical imager - Multispectral and Panchromatic Wide-Scan Camera (WPM), as well as two different multi-spectral radiometers, a Multispectral Camera (MUX) and a Wide Field Imager (WFI).
The unique characteristics of the CBERS constellation are its multi-sensor payloads with different spatial and spectral resolution capabilities and frequencies from each camera allowing for various mapping applications including:
Large scale mosaics
Vegetation indexes and land cover and change detection for monitoring purposes
Monitoring of agricultural harvests, canopy assessment, tree grading, deforestation, forestry, wildfires/forest fires, and infestation
Joint operation with other world data
