GUYADIV forest inventory plots (French Guiana 1986/2018)

Location of the GUYADIV network plots, covering approximately 100 hectares of forest inventories distributed across French Guiana.

Two vector files are provided:
- GUYADIV_Plots, in which each plot is represented by its actual geometry. Two types of plots are distinguished: exhaustive ones and inventories conducted using the "Point-Centered Quarter" (PCQ) method. The spatial accuracy of plot locations depends on the geolocation methods used and is documented in the shapefile. Positional uncertainty ranges from about 1 meter for plots surveyed by a professional surveyor, to around 10 meters for GPS-based locations, and up to 100 meters for plots derived from maps.
- GUYADIV_Plots_X0Y0, which provides, for most inventories, the geographic coordinates of the PCQ starting point or the plot origin (x0, y0).
