Geo-ForPy - Forest Cover Changes in the Paraguayan Chaco - Landsat-5/7/8,1987-2020

The dataset is based on the analysis of forest cover dynamics in the Paraguayan Chaco (northeastern part of Paraguay) between 1987 and 2020. The underlying forest masks were derived through annual forst classifications with a Random-Forest-Classifier trained on Landsat data from 1987 until 2020. The map shows the year in which the forest area was lost.

Statement: This data set provides an overview of 34 years of forest cover losses in the Paraguayan Chaco. The year in which there was the last change of an area from forest to non-forest is represented by its colour. Afforestaton cannot be represented in this dataset.

Description: Geo-ForPy - Forest cover changes in the Paraguayan Chaco 1987-2020 - Processing

Data:

The used forest masks (1987 – 2020) are a product oft he GeoFor-Py project. More information on this data set can be found under the following link.

Processing:

For this overview, the forest masks from 1986 to 2020 were compared with each other. The year in which a pixel changed its value from forest to non-forest was stored in this data set. If there were several changes between forest and non-forest, the last change was saved.

Quality Assurance:

The underlying forest masks have overall accuracies between 85% and 97%. Missclassifications directly affect the derived year of deforestation and can cause salt and pepper effects within continuously deforested areas.
