[R-sig-Geo] Re-projection with project raster results in rotated plot

Hello all, I have a problem concerning re-projecting a raster from EPSG:3035 to sr-org: 29, wrf-lambert-conformal-conic which results in a rotated plot. Here is the code I used: raster1=rasterFromXYZ(radon[, c("x", "y", "rn")]) http://spatialreference.org/ref/epsg/3035/proj4/ crs(raster

[R-sig-Geo] TIF with 3 bands to data frame

Hello all, I am new to rgdal. I downloaded a tif file from 'http://mrdata.usgs.gov/radiometric/data/NArad_U_geog83.tif' which i would like to convert into a regular data frame so that i can plot it using ggplot2. when i tried to read the file using readGDAL i get a warning message NArad_U_g

Re: [R-sig-Geo] reading .grd files

Thank you very much Barry. I converted the .grd file to a .flt file. Now i can work with the map. Also your blog at http://geospaced.blogspot.co.uk/2011/12/reading-afripop-data.html is very informative. Thank you very much for your help. Swagath On Mon, Apr 29, 2013 at 3:08 PM, Barry Rowlingson

[R-sig-Geo] gdalwarp gives different cellsize when re-projected

Dear all, I have a large data-frame with Lon, Lat , Value . Coordinates projected in EPSG:3035 with a resolution of 5 kmx5 km. I converted this into a SGDF. My goal was to project the file into EPSG:4326 with a resolution of 0.05. For re-projecting i converted the file to tif using writeGDA
