Hi All,
I am trying to create a grid but something getting wrong
here is the code
rm(list=ls())
library(maptools)
library(rgdal)
options("digits"=22)
lat=seq(from= -123.4, to= -121.4, length=20)
long=seq(from=48.95, to=49.5, length=10)
#generates the grid
grd = expand.grid(lat,long)
sp_grd <- S
Dear Prof. Roger,
Yes, it's really a reasonable reason.
The conversion method mentioned before by me may be not good, because it
used different scale factors for x and y coordinates. A new correct method
may be explored.
Waiting for your good news.
