The ArcInfo™ or ArcView™ format for Krig output files (which is also the ArcInfo™ format for Map input files) contains a number of header records containing information about the file, followed by a string of z values for each row of the interpolated grid beginning in a particular corner. Unlike GS+ format files, the standard deviation of the estimate and the number of neighbors used for interpolation are not included in this format. Also for this format, the x and y interpolation intervals must be the same (you can set them to be the same from the Interpolation Grid dialog window). This format is compatible with ESRIArc-Info Geographic Information System, and is also called the Ascii Raster File format. Data in this format can be imported directly into ESRIArcInfo™ or ArcView™. Note that this format is different from the ArcView XYZ Input File format., which is an ArcView output format that can be read by GS+.

To convert this file to an ArcGIS™ grid file, use ArcToolbox™, either the light version that comes with ArvView™ or the full version that comes with ArcInfo™:
a. Open ArcToolbox™
b. Choose the Import to Raster tool
c. Specify the GS+ output file name, the grid type (integer or floating point), the name of the grid output file, and press OK.
d. You may now open the file in ArcMap.
