soilproperties | R Documentation |
This indicator allows the extraction of zonal statistics for resource layers
previously downloaded from SoilGrids, thus in total supporting the calculation
of zonal statistics for 10 different soil properties at 6 different depths for
a total of 4 different model outputs (stat). Zonal statistics will be calculated
for all SoilGrid layers that have been previously made available vie get_resources()
.
calc_soilproperties(engine = "extract", stats = "mean")
engine |
The preferred processing functions from either one of "zonal", "extract" or "exactextract" as character. |
stats |
Function to be applied to compute statistics for polygons either single or multiple inputs as character. Supported statistics are: "mean", "median", "sd", "min", "max", "sum" "var". |
The required resource for this indicator is:
soilgrids
A function that returns an indicator tibble with soilgrid layers and statistics as variables and the corresponding statistics as value.
