This repository contains the forest cover in the Paraguayan Chaco for the years 2000, 2010, and 2020 in a vector format. Forest patches smaller than 10 hectras are not contained in this data set. Every forest patch, has stucture describing metrics such as area, perimeter, shape index.

The dataset is available in the WGS 84 / UTM zone 21S - Projected (EPSG:32721). 

The vector data contains following attributes:

gridcode = 100 for every polygon, gridcode 100 stands for "forest"
Area = forest patch area [m^2]
Perimeter = forest patch perimeter [m]
Paratio = Perimeter-Area-ratio (= Perimeter / Area) describes the shape of the forest patch
Shape_Idx = Shape index describes the shape of the forest patch
Frac_Dim = Fractal dimension describes the shape of the forest patch
Prox_100 = Proximity, all neighboring patches within a 100 m distance were considered for calculation
ID = unique id for all forest patches
CA_500 = Core area, area of a forest patch that has at least 500m distance to the patch's border
CAI = Core area index (= CA_500 / Area), share of core area in forest patch area
