write .flt format in R
2 messages · Dan Rosauer, Michael Sumner
You could use rgdal instead: library(raster) library(rgdal) x <- raster(volcano, crs = "+proj=laea") ## so rather than ## writeRaster(x, "file.flt") writeGDAL(as(x, "SpatialGridDataFrame"), "file.flt", drivername = "EHdr") ## see this for the drivers available gdalDrivers() But that format is not very well defined, so I would test carefully that your target is satisfied. See here for some info: http://www.gdal.org/frmt_various.html#EHdr http://geospaced.blogspot.co.uk/2011/12/reading-afripop-data.html Cheers, Mike.

Hi
Can anyone advise on an R method to write a raster object to the ESRI .flt grid format?
writeRaster accepted the *.flt filename, but silently handled it by actually saving to *.grd, *.gri files which are the DIVA format.
I can do it by roundabout methods, eg writing to .asc and then converting in DIVA or ArcGIS. But a direct method would save much time and fiddling.
Thanks for your help.
