DETER (Deteccao de Desmatamento em Tempo Real) is INPE's near-real-time deforestation and forest degradation alert product for Brazil, distributed openly through the TerraBrasilis platform.^[1]^[2] The current DETER-B configuration uses imagery from CBERS-4A WFI, Amazonia-1 WFI, and ResourceSat-2 AWiFS as supplementary input; native spatial resolution for the primary sensor chains is in the range of 56 to 64 metres per INPE's sensor documentation; a product-level specification confirming the effective pixel size of DETER outputs was not available in publicly accessible INPE sources as of May 2026.^[3] DETER alerts are generated for the Brazilian Amazon and Cerrado biomes; a November 2023 expansion added Pantanal and Amazon non-forest coverage on an experimental basis, subject to ongoing adjustment.^[2]

The product is a rapid-detection alert layer, not an authoritative deforestation area estimate; confirmed annual figures are produced separately by PRODES.^[4] Alerts trigger enforcement by IBAMA and feed Brazil's REDD+ safeguard reporting and EUDR supply-chain monitoring workflows.^[2] Minimum mapping unit is widely cited in operational documentation as approximately 1 hectare; a tier-1 INPE methodology document confirming this figure was not available in publicly accessible sources as of May 2026.^[3]

Note on sensor nomenclature: earlier DETER-A used CBERS-2B WFI; legacy literature sometimes labels this camera as "AWiFS", which is incorrect; AWiFS is an instrument family of the Indian IRS-P6 satellite, not a CBERS sensor.^[3]
