rmGeoIdentity {ClimMobTools}

Remove geographical identity

Description

Build a buffer around the a set of geographical coordinates and take a random point around the buffer. The function is used to omit the precise location of tricot participants but keeping a close distance to its agro-environment

Usage

rmGeoIdentity(longlat, dist = 0.015, nQuadSegs = 2L, ...)

Arguments

longlat

a data.frame or matrix with geographical coordinates long lat

dist

numeric, buffer distance for all lonlat

nQuadSegs

integer, number of segments per quadrant

...

further arguments passed to sf methods

Value

A data frame with the random coordinates long lat whithin a pre-defined buffer

Examples

xy <- matrix(c(11.097799, 60.801090,
               11.161298, 60.804199,
               11.254428, 60.822457),
             nrow = 3, ncol = 2, byrow = TRUE)

rmGeoIdentity(xy)

#' the function also handles NAs

xy2 <- matrix(c(11.097799, 60.801090,
                NA, NA,
                11.161298, 60.804199,
                11.254428, 60.822457,
                11.254428, NA),
              nrow = 5, ncol = 2, byrow = TRUE)

rmGeoIdentity(xy2)
