Description

This function is required to extract pixel values of multiple stacked raster files at specific locations.

Usage

extract_stack_raster(x, y)

Arguments

x	Path to folder containing Raster files
y	Object of class SpatialPoints

Value

Dataframe. A matrix of extracted point location information for respective Raster files

library(raster)
x <- list.files(path = "foleder containing raster files", pattern = glob2rx("*.file extension"), full.names = TRUE)

pnts <- data.frame(Long = c(10:15), Lat = c(1:5))
coordinates(pnts) = ~ Long + Lat
proj4string(pnts)<- CRS("+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0")
y <- pnts
