constantDensitySampling: Constant Density Sampling

In sharpshootR: A Soil Survey Toolkit

Constant Density Sampling

Description

Perform sampling at a constant density over all polygons within a SpatialPolygonsDataFrame object.

Usage

constantDensitySampling(x, polygon.id='pID', parallel=FALSE, cores=NULL, 
n.pts.per.ac=1, min.samples=5, sampling.type='regular')

Arguments

x	a SpatialPolygonsDataFrame object in a projected CRS with units of meters
polygon.id	name of attribute in x that contains a unique ID for each polygon
parallel	invoke parallel back-end
cores	number of CPU cores to use for parallel operation
n.pts.per.ac	requested sampling density in points per acre (results will be close)
min.samples	minimum requested number of samples per polygon
sampling.type	sampling type

Value

a SpatialPointsDataFrame object

Note

This function expects that x has coordinates associated with a projected CRS and units of meters.
