# MapBiomas Alerta
*analysis-service . products*

Brazilian deforestation alert validation and refinement system operated by the MapBiomas coalition. Aggregates alerts from multiple monitoring platforms (DETER, SADs, GLAD, SIRAD-X) across all six Brazilian biomes, then validates and refines each event using PlanetScope satellite imagery at 3.7 m resolution via Google Earth Engine. Publishes weekly validated alert polygons with before-and-after imagery, pressure-vector attribution, and property-level reports searchable by CAR (Cadastro Ambiental Rural) code. Monitoring period January 2019 to present. Operationally distinct from the annual MapBiomas land-cover collection: Alerta detects discrete native vegetation loss events rather than classifying full landscapes. Coordinated by the same MapBiomas coalition (co-creators include LAPIG, Imazon, IPAM, SOS Mata Atlantica, UFRGS, and approximately 14 further universities and NGOs); technical collaborators include IDS, The Nature Conservancy, Imaflora, ISA, and WWF. The manufacturer FK resolves to the mapbiomas consortium company entry; INPE contributes data feeds and participates in the Scientific Advisory Committee but is not an operating institution for Alerta.

## Editorial
MapBiomas Alerta is a Brazilian deforestation-alert validation and refinement service operated by the MapBiomas coalition across the six Brazilian biomes.[^alerta-home-en] It aggregates alerts from monitoring systems including DETER, SAD, GLAD, and SIRAD-X, then validates and refines events with PlanetScope imagery in Google Earth Engine.[^alerta-method] The methodology uses analyst validation, false-positive rejection, and supervised Random Forest boundary refinement from high-resolution before-and-after image pairs.[^alerta-method] Published outputs include validated alert polygons, before-and-after imagery, pressure-vector attribution, and property-level reports linked to rural property and protected-area overlays.[^alerta-method][^alerta-home-en] The platform provides API access for alert retrieval and integration, alongside web downloads and GIS workflows for downstream users.[^alerta-api][^alerta-home-en]
