Tree Cover Loss (FORMA) Alerts - Humid Tropics

This data set is from Global Forest Watch and indicating satellite data of tree loss cover alerts (humid tropics) for the Lao PDR. These are known as Forest Monitoring for Action (FORMA) alerts. There are files of a number of different formats with data from 2006 to 2015.

Use limitations We understand the value of open data. Every day, we rely on data and research created by others to conduct our work. We also believe that open data inspires participation and innovation, and increases our reach in providing governments, businesses, and people the necessary tools to make informed decisions. Finally, we believe that our work stands up under scrutiny, and allowing others to see the data behind our analyses ensures that it does. WRI has a long history of publicly sharing data, from our earliest hard copy data tables in the original World Resources Report to the continued work of The Access Initiative promoting the right to information. We are now challenging ourselves to expand the scope and comprehensiveness of our data sharing.

Positional Accuracy 500 meter resolutions. There is a considered effort to keep false positive alerts (those that mistakenly highlight forest loss) to a minimum, so some potential clearing activity does not appear on the map.
Logical Consistency No known issues with logical consistency
