calc_similarity: Calculate climatic similarity

In CIAT-DAPA/analogues: Identification of Climate Analogues

Description

Uses the parameters specified by the function createParameters. Extracts climatic data from the reference site and compares with every pixel in the search range. Returns a map (RasterLayer) of the search range filled with the calculated climatic similarity.

Usage

calc_similarity(params)

Arguments

params

List of required input parameters, as specified to function createParameters

Value

RasterLayer with the calculated similarity.

Examples

data(climstack) #contains 2 RasterStack objects: prec and tavg

#create params, give equal weights to both variables
params <- createParameters(x=-75.5, y=3.2, vars=c("prec","tmean"),weights=c(0.5,0.5),
                        ndivisions=c(12,12),growing.season=c(1,12),rotation="tmean",threshold=1,
                        env.data.ref=list(prec,tavg), env.data.targ=list(prec,tavg),
                        outfile="~/.",fname='similarity',writefile=FALSE)

#calculate similarity
