GOOGLE EARTH ENGINE

MapBiomas uses technology from the Google Earth Engine platform. We provide scripts to facilitate access to the MapBiomas collections.

To access and run follow the instructions below:

  • With a Gmail account, sign up for the Google Earth Engine Platform through this link https://earthengine.google.com
  • In a few days, you will receive authorization to access the platform.
  • Once registered in Google Earth Engine, insert the link of the scripts you want to run.
  • Change the parameters to get the map you want.

We encourage SCRIPT MAPBIOMAS users to send us their suggestions for innovation so that we can constantly improve it.

TVI (TEMPORAL VISUAL INSPECTION)

Open source online tool for visual inspection of sample points in historical Landsat satellite remote sensing image series.
Created by the Image Processing Laboratory of the Federal University of Goiás (LAPIG - UFG), TVI provides subsidies that facilitate and streamline the process of interpreting satellite series for the training and calibration of image classification algorithms.
In MapBiomas, TVI was mainly used to obtain validation points of the annual pasture area distribution mappings in the Brazilian territory.
