Generate sampling points within a SpatialPolygon object, according to a specified sampling density.
1 2 | sample.by.poly(p, n.pts.per.ac=1, min.samples=5,
sampling.type='hexagonal', iterations=10, p4s=NULL)
|
p |
a Polygon object, with coordinates in a projected CRS |
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, see |
iterations |
number of tries that |
p4s |
a qualified proj4string that will be assigned to sampling points |
This function is typically accessed via some kind of helper function such as constantDensitySampling
.
A SpatialPoints
object.
This function expects that the Polygon
object has coordinates associated with a projected CRS– e.g. units of meters.
