A class for GlobalSoilMap soil property maps

Description

A class containing predictions of target soil property at six standard depths following the GlobalSoilMap.net specifications: sd1 = 2.5 cm (0–5), sd2 = 10 cm (5–15), sd3 = 22.5 cm (15–30), sd4 = 45 cm (30–60), sd5 = 80 cm (60–100), sd6 = 150 cm (100–200).

Slots

varname:

object of class "character"; abbreviated variable name registered in the Global Soil Data registry

TimeSpan:

object of class "list"; contains begin and end of the sampling period of class "POSIXct"

sd1:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 2.5 cm (0–5)

sd2:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 10 cm (5–15)

sd3:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 22.5 cm (15–30)

sd4:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 45 cm (30–60)

sd5:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 80 cm (60–100)

sd6:

object of class "SpatialPixelsDataFrame"; predictions and variances, or number of realizations of the target variable at depth 150 cm (100–200)
