as.points: Conversion to a SpatVector of points

In terra: Spatial Data Analysis

Conversion to a SpatVector of points

Description

Conversion of a SpatRaster, SpatVector or SpatExtent to a SpatVector of points.

Usage

## S4 method for signature 'SpatRaster'
as.points(x, values=TRUE, na.rm=TRUE, na.all=FALSE)

## S4 method for signature 'SpatVector'
as.points(x, multi=FALSE, skiplast=TRUE)

## S4 method for signature 'SpatExtent'
as.points(x, crs="")

Arguments

x	SpatRaster, SpatVector or SpatExtent
values	logical; include cell values as attributes?
multi	logical. If TRUE a multi-point geometry is returned
skiplast	logical. If TRUE the last point of a polygon (which is the same as the first point) is not included
na.rm	logical. If TRUE cells that are NA are ignored
na.all	logical. If TRUE cells are only ignored if na.rm=TRUE and their value is NA for all layers instead of for any layer
crs	character. The coordinate reference system (see crs)

Value

SpatVector

Examples

r <- rast(ncols=2, nrows=2)
values(r) <- 1:ncell(r)

as.points(r)

if  (gdal() >= "3.0.0") {
	p <- as.polygons(r)
	as.points(p)
}
