Disasters Charter

These maps use radar data from RADARSAT and #Sentinel1 to estimate the extent of flooding along the Dulce River at Santiago del Estero in Argentina: bit.ly/4dmYIv9

These maps use data from the #RCMSatellites, KOMPSAT-5, #Sentinel1, and SAOCOM to estimate flooded areas in southern Tucuman in Argentina as of 12 and 15 March: bit.ly/4dmYIv9

The Charter has been activated to provide satellite data over the flood in Argentina: bit.ly/4dmYIv9 Our first maps use #Sentinel1 data to estimate affected areas in southern Tucuman.

We've published a new article, in which UAESA look back on last year's 25th anniversary of the Charter, reflecting on achievements and evolution during the past quarter century: bit.ly/4tZDJVf

The Charter has been activated to provide satellite data over the flood in Peru: bit.ly/4cgvbmv

The Charter has been activated to provide satellite data over the flood and landslides in Brazil: bit.ly/4azRDWx

These maps use a combination of optical and radar satellites to estimate the impact of the flood in Colombia, using data acquired before and afterwards: bit.ly/4aM1t7F

It has been a packed and impactful week of activities at RCMRD. We successfully concluded the Regional Symposium 2026 – “Space Technologies for Humanity” (16–17 February) and immediately transitioned into the Regional Training on Space Technologies for Disaster Management and the Use of COS-2 and the Charter Mapper during Activations (17–20 February). Organized by RCMRD, the back-to-back engagements were held with the support of the @UNOOSA) through the @UN_SPIDER programme, the University of Bonn – Centre for Remote Sensing of Land Surfaces @ZFL, and the International Charter on Space and Major Disasters. From high-level Disast3r risk reduction dialogue to hands-on operational training, participants strengthened their capacity to activate the Charter through the COS-2 web platform and mapping using the Charter Mapper, translating EO data into actionable information for disaster response. #DisasterManagement @czaran #chartermapper @DisastersChart

Over the past 3 days, participants in the Regional Training on Space Technologies for Disaster Management and the use of COS-2 and the Charter Mapper have been strengthening their skills in applying space technologies to real-world disaster response. 🛰️🌍 Through hands-on sessions, they have learned about the different roles in COS-2 -including Authorized Users, Project Managers, and End Users -and workflows on the Charter Mapper for mapping floods, droughts, earthquakes, landslides, and wildfires. The final outputs from these workflows can be transformed into actionable disaster response products, enabling faster, smarter, and more effective emergency management. @DisastersChart @czaran @aamdihun @IGAD_CPAC @allanoware @UNOOSA @UN_SPIDER @Vittorio Trivigno @RobertoBiasutti @MichaelSchmidt

When disaster strikes, response time is critical. The International Charter on Space and Major Disasters provides free satellite imagery to support countries affected by #floods, #earthquakes, #landslides, #cyclones, and other major disasters. Authorized users can activate the Charter 24/7 through a single access point - and within hours or days, receive analyzed satellite maps to guide emergency response and recovery efforts. This global collaboration of space agencies ensures that critical Earth observation data reaches those who need it most -helping save lives, protect infrastructure, and safeguard the environment.

These maps use #Sentinel1 data to estimate the areas affected by floods in Colombia between 2 and 14 February: bit.ly/4aM1t7F

These maps use radar data from the #RCMSatellites to estimate flooded areas at Ambatondrazaka, Brickaville, and Lake Alaotra in Madagascar after #CycloneFytia: bit.ly/3NXYEYk

This map uses #Pleiades imagery from 10 February to estimate flooded areas in Santa Cruz de Lorica in Colombia: bit.ly/4aM1t7F

The Charter has been activated to provide satellite data over the flood in Colombia: bit.ly/4aM1t7F Our first map of the disaster uses #Sentinel1 data to estimate flooded areas at San Bernardo del Viento.

Consult the latest analysis for #floods in Boeny Region, #Madagascar from our web map: ~3,000 km² of land appears to be affected by floodwaters ~36,300 people are potentially exposed to or living close to flooded areas ➡️unosat.org/products/4234

📅 18–20 February 2026 RCMRD will host a training on: The Space Technologies for Disaster Management: Use of COS-2 and the Charter Mapper during activations 🌍🛰️ With the support of @UN_SPIDER , the Centre for Remote Sensing of Land Surfaces @ZFLbonn at the University of Bonn, and the International Charter: Space and Major Disasters, this training will strengthen regional capacity in East Africa for the use of Earth Observation #EO and space-based solutions in disaster preparedness and response. @DisastersChart @Esri @SpaceAgencyKE @NDOCKenya @SoDMA_Somalia @IGAD_CPAC @AfSA_AU

The Charter has been activated to provide satellite data over #CycloneFytia's impact to Madagascar: bit.ly/3NXYEYk

These maps use optical and radar data from #Pleiades and #Sentinel1 to estimate the impact of floods and landslides in New Zealand after the recent storm: bit.ly/3OcZqAA

The Charter has been activated to provide satellite data over a storm in New Zealand: bit.ly/3OcZqAA Radar data from #Sentinel1 and the #RCMSatellites was used to estimate flooded areas.

The Charter has been activated to provide satellite data over the flood in Mozambique: bit.ly/49ZYcjD Our first maps of the disaster use #Sentinel1 data to estimate flooded areas.
