Emerging Hot Spots and Tracking Global Forest Loss: A New Chapter in GIS for Science

Deforestation impacts the environment in many ways. Habitat loss, desertification, increased greenhouse gas emissions, and climate change are just some of the negative effects. In an effort to understand trends in deforestion, Blue Raster collaborated with the World Resources Institute and Esri to publish a study about using spatial statistics to identify Emerging Hot Spots of forest loss. We are excited to announce that this work is part of a new publication.

GIS for Science

Featured in the new Esri Press book, GIS for Science, “Tracking Global Forest Loss” explores the study and the use of advanced geospatial tools to analyze and monitor forest loss throughout Brazil, Colombia, the Democratic Republic of the Congo, and Indonesia.

GIS for Science: Applying Mapping and Spatial Analytics, Volume 2 will officially be released in October 2020, but the pre-release volume is available digitally at this year’s Esri User Conference.

Using Esri’s Emerging Hot Spot Analysis, Blue Raster helped develop a workflow for mapping changes of deforestation through time and visualizing the impact of environmental policy across the world. The Emerging Hot Spot Analysis tool detects trends in data by analyzing new, intensifying, diminishing, and sporadic hot and cold spots. When analyzing for deforestation trends, Blue Raster worked to identify continual trends for hot spots of tree cover loss and cold spots of diminishing loss.

As the threat to our environment grows, scientists are working with cutting-edge GIS technology to help decision makers, technical experts and the broader public better understand trends in deforestation and improve future forest monitoring. With the ability to quantify deforestation loss over time, governments and other interest groups can create more effective policy over time.

Global Forest Watch Fires: New Fire Monitoring Capabilities

Thousands of fires are burning in the Amazon rainforest in Brazil - the most intense blazes for almost a decade. Global Forest Watch Fires (GFW Fires), an online platform for monitoring and responding to forest and land fires, provides a near real-time view into the current fire activity. Additionally, users can view fire reports and compare historical data on regions all over the world.

New Updates to GFW Fires

Blue Raster recently worked to add new features and capabilties to the Global Forest Watch Fires application. Want to see details for a specific area on the map? Draw or upload a shapefile to calculate fire counts and subscribe to alerts. Users can select specific areas and see the calculated numbers of VIIRS and MODIS Alerts in the past 24 hours. Next, users can click on the drawn or uploaded shapes on the map to subscribe to alerts for that area.

Global Forest Watch Fire Reports provide robust insight into fire history, cumulative fires to date, and a statistical analysis by administrative boundaries within a country or around the world. New to GFW Fires, users can now view charts of unusual fire activity. The report compares fires from the current week to the same week in the previous 16 years. In addition, new charts analyze fire activity in Palm Oil Concessions and Wood Fiber Areas.

In addition to the basemap imagery, Global Forest Watch Fires now provides an option for Sentinal Imagery. The latest satellite imagery is available from Sentinel-2 and Landsat 8. Sentinel-2, operated by the European Space Agency, has global coverage in 10-meter resolution, and can obtain updated imagery every 10 days.

By using the latest geospatial technology, Global Forest Watch Fires allows anyone to access near real-time information about where and how forests are changing around the world. Users can monitor fire activity, sign up to receive alerts, or share their own stories on GFW's blog. Explore this interactive map today.
