Analyze data within an area on the map

The analysis tool is an easy way to assess forest change within an area on the map. You can analyze countries, subnational areas, shapes from contextual layers or custom areas. The analysis tool is also useful for generating visualizations and data charts that can be used in policy briefs, reports and articles.

Below you will find information on which data layers are compatible with the analysis tool; as well as how to run analyze a country or subnational region, how to analyze a contextual “area of interest” layer and how to analyze a custom area on the map.

Data layers compatible with the analysis tool

In general, there are two ways to think about the data layers on GFW with regards to the analysis tool. The first is activating a data layer to define a boundary; the second is activating a data layer to feature within the analysis itself. We can think about this distinction as: “Area of interest” data layers and “research” data layers.

“Area of interest” data layers refer to user-defined areas and data layers that outline distinct boundaries – many of these data layers are found in the “Land Cover” and “Land Use” categories, and are mainly vector data.
“Research” data layers refer to data layers that indicate a measurement or change – many of these data layers are found in the “Forest Change” category and are primarily raster data.

Below are the data layers compatible with the analysis tool and categorized as either an “area of interest” data layer or a “research” data layer.

Area of interest (data layers defining a boundary that can be clicked on and featured as a target for analysis)Research (data layers indicating a measurement that can be activated to provide information on changes within an area – will appear in the analysis widget)
Tree plantations (Land Cover)GLAD deforestation alerts (Forest Change)
Logging concessions (Land Use)VIIRS fire alerts (Forest Change)
Mining concessions (Land Use)Tree cover gain (Forest Change)
Oil palm concessions (Land Use)Tree cover loss (Forest Change)
Wood fiber concessions (Land Use)Tree cover loss by dominant driver (Forest Change)
Palm oil mills (Land Use)Tree cover (Land Cover)

Analyze a country or subnational region

  1. To run an analysis at the country or subnational level on the map, first click on the “Analysis” tab located on the legend/analysis panel.
Click on the “Analysis” tab to access the tool.
  1. From there, you are presented with two options: “Click a layer on the map” and “Draw or upload shape.” Select the “Click a layer on the map” option and then click on the map layer you wish to analyze. Zooming out will allow you to select an entire country, while zooming in will allow you to select subnational boundaries. You can also use the search tool on the bottom left to find the country, province, state or district that you’d like to analyze. Learn more about searching for an area here.
Zoom out to select a layer at the country level.
Zoom in to select layers at the subnational level.
  1. Once you click on a layer, the analysis will automatically run and produce data charts within the legend/analysis panel. The default analysis will provide you with data on tree cover loss, tree cover gain and tree cover. To include more data charts, you will need to activate additional “research” data layers.
Click on Cambodia to activate the analysis and produce results for that country.

Analyze a contextual layer

  1. There are some contextual layers – or “area of interest” data layers – on GFW that you can use to conduct analyses specific to the data. For example, under the “Land Use” category, you can activate “Protected areas.”
Click the icon to left of “Protected areas” to activate that layer.
  1. Click on the protected area layer that you want to run an analysis on and click “Analyze.” The analysis will automatically run and produce data charts within the legend/analysis panel. To include more data charts, you will need to activate additional “research” data layers.
Click on the protected area layer you’re interested in, then click “Analyze” to run the analysis.
The analysis will activate and produce results for that area.

Analyze a custom area

  1. If you have a specific area of interest you would like to monitor and analyze that is not part of an existing data layer on GFW, you can use the analysis tool to draw a shape or upload a shapefile. Get started by navigating to the “Analysis” tab on the legend/analysis panel and clicking “Draw or Upload Shape.”
  2. To draw a shape, click “Start Drawing” and define your area of interest by clicking on the map to place points. You will need to close the shape by returning to the first point you placed and clicking on it.
Click on the map to place points and define the boundaries of your area of interest.
  1. Once your shape is complete, the analysis will automatically run and produce data charts in the analysis tab.
Complete your shape to activate the analysis and produce the results for that area.
  1. You can also upload your own shapefile. To upload a shapefile, select a file from your computer and drag and drop into the analysis box. You will only be able to upload and analyze one shapefile at a time; however, there is no limit to the total number of shapefiles you can upload to the map. The recommended maximum file size is 1MB – anything larger than that may not work properly.
  2. The shape will appear on the map and the analysis will automatically run and produce data charts in the analysis tab.

No matter which approach you use, once your analyses are complete you will have the options to subscribe to the data in the region of your analysis or explore it further on a dashboard. Click “Save in My GFW” to log in and save the area and subscribe to notifications that will alert you when forest changes are detected.
