Abstract:
This repository contains data on the forest structure and forest cover dynamics in the Paraguayan Chaco (northeastern part of Paraguay) between 1987 and 2020. The products displaying results on the forest cover dynamic base on annual forest cover masks at 30 m resolution. These were derived through a classification of forest and non-forest areas using a random forest classifier trained on Landsat data.
The annual forest masks were used to generate further products which are also contained in this repository: Annual forest cover per district, forest cover changes in protected areas, information on the degree of forest fragmentation and a detailed overview map showing where and when forest was lost in the Paraguayan Chaco. Additionally, this repository comprises the result of a forest structure modelation based on Sentinel-1, Sentinel-2 and GEDI data, and provides information on e.g. the plant area index, or the canopy height.
