About TMF#

The European Commission’s Joint Research Centre developed this new dataset on forest cover change in tropical moist forests (TMF) using 38 years of Landsat time series. The wall-to-wall maps at 0.09 ha resolution (30m) depict the TMF extent and the related disturbances (deforestation and degradation), and post-deforestation recovery (or forest regrowth) through two complementary thematic layers: a transition map and an annual change collection over the period 1990-2019. Each disturbance (deforestation or degradation) is characterized by its timing and intensity. Deforestation refers to a change in land cover (from forest to non-forested land) when degradation refers to a temporary disturbance in a forest remaining forested such as selective logging, fires and unusual weather events (hurricanes, droughts, blowdown).

TMF Explorer#

The Tropical Moist Forest Explorer is a web-mapping tool that shows the dataset and allows users to navigate the tropics visualizing the main layers of the Tropical Moist Forest dataset without installing any software. We recommend its use to explore the TMF product

Data Users Guide#

For a description of the TMF datasets and details on how to use the data, you can download the Data USers Guide.

Usage#

Select an AOI#

Using the provided AOI selector, select an AOI of your choice between the different methods available in the tool. We provide 3 administration descriptions (from level 0 to 2) and 3 custom shapes (drawn directly on the map, asset or shapefile).

aoi selector#

Note

If a custom aoi from shape or drawing is selected, you will be able to use it directly and the upload to GEE will be launched in the background

Select parameters#

You need to select the start and final year of your analysis. TMF let you choose from 2014 to 2019. Then you need to select what is the output you want to display on the map:

  • Deforestation

  • Degradation

  • Annual change

Click on the validation button and your data will be automatically displayed on the map. If you want to change one of them you’ll need to click on the button again.

Export#

Once you’re happy with the information displayed then can be exported to be further used in a GIS software or in a GEE process. The tool provide 2 main exportation options, as an asset(in GEE) or as a Tif file in SEPAL.
