Description

Extract mean summer NDVI values for buffers around lat/long points

Usage

1
processNDVI(filepath, points, buffer, northern_summer = T, n_cores)

Arguments

filepath

A character string stating the path to the folder where raw Gimmsfiles are stored (downloaded using downloadGimms)

points

A dataframe of points with columns Latitude and Longitude

buffer

Positive numeric value stating the length (in meters) of the desired buffer radius. Mean values of the climate variable will be calculated for each point from within this buffer

northern_summer

Logical. If TRUE, calculate NDVI for the northern hemisphere summer using July observations. If FALSE, calculate NDVI for southern hemisphere summer using January observations. Default is TRUE

n_cores

Positive integer stating the number of processing cores to split the job across. Default is parallel::detect_cores() - 1
