Desborde de lago glaciar

A study conducted by Swiss and Chinese scientists assesses the flood danger posed by glacial lakes across the Tibetan Plateau using an automated satellite survey. 

Glacial lake outburst floods (GLOFs) are a major concern throughout the Third Pole Environment, where thousands of glacial lakes have formed and continue to expand in response to climate warming and glacial retreat. This is particular true in the Himalaya, where several disasters occurring over the past century have caused significant loss of life and damage to infrastructure. The fear is that these lakes can overtop their barriers and send floods downstream that overrun settlements.

The study looked at 1,300 of these water bodies that have built up in front of ice streams and which are dammed by rocky debris, and identified 210 lakes (16 per cent) with a potential to threaten communities. This information facilitates targeted local monitoring and other risk reduction...

Sentinel Hub, together with the European Earth Observation programme Copernicus and the European Space Agency, are looking for new and innovative ideas and scripts for Sentinel data processing and visualization. The contest will run until 5 May 2019 and all the entries will be judged by a jury of experts on functionality and usefulness, as well as possible commercial value.

The EU Earth Observation Browser and similar services are made possible through open data policies, which allow everyone to access and use satellite data. Thanks to these policies a wide variety of fields are creating applications for satellite data, however, they need support to make use of the data for these applications. Custom scripts are an easy and quick way to add value to already available data and rapidly test new algorithms.

The Sentinel Hub Custom Script Contest is a remotely run hackathon engaging data...

As part of it advisory support activities, UN-SPIDER is carrying out out a Technical Advisory Mission (TAM) to Peru from 1 to 5 April to evaluate the current and potential use of space-based information in all aspects of disaster management. Based on exchanges with a wide range of stakeholders, UN-SPIDER will provide recommendations as to how to strengthen the use of space-based information in disaster risk management and emergency response in the country.

The team of experts led by UN-SPIDER is conducting multiple activities and institutional visits in Lima. The team is comprised of eight experts from UN-SPIDER; the German Aerospace Centre (DLR); the Argentinian National Space Activities Commission (CONAE); the Mexican Space Agency (AEM); the Agustin Codazzi Geographic Institute of Colombia (IGAC); the Santa Maria...
