Hi R-user,
I was trying to make a raster map with WGS84 projection in R, but I could not
make it. I found one data set in Google that data is almost the same format as
of mine. I wanted to make a raster map of temperature with 1 degree spatial
resolution for the global scale.
I could make it in GIS software but I do have many variables (to be many raster
images) and ultimately I am importing them to R for further analysis.
Therefore, I wanted to make them in R, if possible.
It would be great if you give some hints on how script look like in creating a
raster map from my own data set (I have provided link for your references, this
is an example data set).
I am really appropriating for your help.
#--------------------------------------------------
#create a raster map from scratch
install.packages("raster", dependencies=TRUE)
library(raster) # raster data
install.packages("rgdal", dependencies=TRUE)
library(rgdal) # input/output, projections
install.packages("rgeos", dependencies=TRUE)
library(rgeos) # geometry ops
install.packages("spdep", dependencies=TRUE)
library(spdep) # spatial dependence
install.packages("pastecs", dependencies=TRUE)
library(pastecs)
pts<-read.table.url("https://www.betydb.org//miscanthusyield.csv";, header=T,
sep=",")
proj4string(pts)=<- CRS("+proj=longlat +datum=WGS84")
#---------------------------------------------------------------------------
Cheers,
Kristi
