SAM Satellite

Amazônia-1 is the first Earth Observation satellite completely designed, integrated, tested and operated by Brazil. It features the optical Advanced Wide Field Imager (AWFI), with swath width 850 km and 60 m resolution, capturing images in 3 visible bands and 1 near-infrared (NIR) band. It has a high revisit period of 5 days, which is important for increasing the probability of capturing useful images over frequently overcast areas including the Amazon region. The data will be accessible to the scientific community, government agencies, and to users interested in a better understanding of the terrestrial environment. The Amazon mission is planned to have three remote sensing satellites: Amazonia-1, followed by Amazonia-1B and Amazonia-2.

Peru’s first Earth Observation satellite was commissioned by the Peruvian government for its national space agency, CONIDA (Comisión Nacional de Investigación y Desarrollo Aeroespacial) in 2014, and constructed in a record time of less than 24 months. PerúSAT-1 features the very-high-resolution optical New AstroSat Optical Modular Instrument (NAOMI) imager designed and developed by Airbus Defence and Space. This silicon carbide optical instrument provides panchromatic images with 70 cm spatial resolution and multispectral images in up to 2 m spatial resolution. PerúSAT-1 is based on Airbus Defence and Space’s AstroBus-S platform, and captures up to 300 images covering an area of 63, 000 km2 per day.

According to the latest issue of an annual disaster statistics report, floods were the deadliest type of disasters in 2019, followed by extreme temperature, while storms affected the highest number of people. Published by the Centre for Research on the Epidemiology of Disasters (CRED), “Natural disasters 2019 - Now is the time to not give up” draws on data recorded in the Emergency Events Database (EM-DAT), which saw the addition of 396 disasters that affected a total of 95 million and caused $103 billion in economic losses around the world. 

Accounting for 40 per cent of disaster events, Asia suffered the highest impact with 45 per cent of deaths and 74 per cent of total affected. India, which saw cyclone Fani cause destruction in 2019, was the country most affected... read more

Recommended Practices

La gestión del riesgo de desastres suele contar con el apoyo de las tecnologías de teledetección durante las diferentes etapas de un desastre. Estas tecnologías junto con los datos geoespaciales encuentran su aplicación sobre todo durante la evaluación de riesgos, la elaboración de modelos de escenarios o la alerta temprana, a pesar de que las medidas preventivas también pueden apoyarse en estas innovaciones. Esta Práctica Recomendada de UN-SPIDER se centra en las medidas preventivas que pueden adoptarse de antemano, utilizando los datos de teledetección sobre las inundaciones y los datos...
Remote sensing technologies can support all stages of the disaster management cycle. In the prevention and preparedness phases, they often find their application in risk assessments, scenario modelling and early warning. This UN-SPIDER Recommended Practice explains how remote sensing data about recurring floods, information about infrastructure and socio-economic data can be integrated using free and open source software to support prevention and preparedness efforts. It makes use, among others, of the InaSAFE plug-in for the desktop GIS software QGIS to estimate the number of people and...
