Hello, Is there anyone who could give me an example of how to import an ascii grid (i.e. ArcGIS exported raster) into R. I want to use it with gstat but don't know the appropriate import routine.
On a Unix/Linux platform, you can use the rgdal library (after having compiled and installed the external GDAL libraries). But if you look at the grid file in a text viewer/editor, you'll see that its format is very simple, so reading using connections is quite possible. See
?connections
and
?readLines
should do it in a platform-neutral way.
Thanks very much for your help. Regards, femke Femke Reitsma Graduate Student (ABD) Geography Department 2181 LeFrak Hall University of Maryland College Park, MD 20742 Phone: 301-405-4121 E-mail: femke at geog.umd.edu http://www.glue.umd.edu/~femke/ [[alternative HTML version deleted]]
