remapcon: Conservative remapping

Description

Implements conservative remapping, weighting with the overlap area between pixels.

Usage

remapcon(x, y, z, xo, yo)

Arguments

x

vector of input longitudes

y

vector of input latitudes

z

matrix of input data

xo

vector of target longitudes

yo

vector of target latitudes

Value

A remapped matrix of dimensions c(length(xo), length(yo))

Examples

# NOT RUN {
z <- 1:(31*51)
dim(z) <- c(31, 51)
x <- seq(4, 10, 0.2)
y <- seq(30, 40, 0.2)
xo <- seq(5, 6, 0.5)
yo <- seq(35, 37, 0.5)
zo <- remapcon(x, y, z, xo, yo)
