The researchers behind the map hope that it will help governments around the world better understand and protect increasingly threatened coral reefs. “There are countries, organizations and government agencies in the world that don’t have a map of their reefs […] so these maps will help peopl...
The study introduces how to map coral reefs distribution by satellite image processing and evaluate the map with the ground truth data and the visible interpretation method. In the error matrix utilizing all 93 ground survey points, the overall accuracy was achieved 78%, which indicated similar ...

The framework can utilize a wide range of input covariate and training data sources, and outputs both geomorphic and benthic map types. The maps presented are the largest ever coral reefs maps produced from a consistent and transparent remote sensing approach....

阅读理解 Coral reefs (珊瑚礁) are among the most productive ecosystems in the world. They're also in serious danger—climate change and other threats are killing them off. But researchers have come up with an invention they think could help the reefs: 3D-printed corals. ...
Reefs at Risk: Map-Based Analyses of Threats to Coral Reefs Definition Reefs at Risk is a series of publications, produced by the World Resources Institute (WRI) in collaboration with partner organizations, that provides detailed spatial analyses of threats to the world's coral reefs. Reefs at ...
In this way, the global online map has been built. To make it more correct and detailed, the team reached out to over 900 scientists and organizations from around the world, generously sharing almost 500 of their own datasets of coral reefs. The datasets enable the team to mark the exact...
