Hello:
I am using R raster package to replace ArcGIS when processing multiple shp
files. However, when I export R raster back to ArcGIS, it couldn't recognize
R raster file correctly. For example, I used {raster} package and got a
RasterLayer as followed.
class : RasterLayer
dimensions : 8280, 18480, 153014400 (nrow, ncol, ncell)
resolution : 0.008333334, 0.008333334 (x, y)
extent : -169, -14.99999, 6.000003, 75.00001 (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +ellps=WGS84 +no_defs
data source :
G:\_RESEARCH\_GRADUATE\BiodiversityVsGradients\Little_in_R\LittleRasterAll.bil
names : LittleRasterAll
I used function writeRaster{raster} to write this rasterLayer into every format
it supports, and ArcGIS respond to them in three different ways, but none of
them works. I wonder why it happens and if there is someway to solve this
problem?
ArcGIS respond type:
1. Show strange values
GTiff, HFA
2. Show even values in whole raster
IDRISI, ascii, EHdr
3. Cannot recognize files
CDF, raster, SAGA, CDF , ENVI
