Esri ASCII export-import

geoinf
Dear friends,

Does ILWIS map export to the Esri ASCII file format works correctly?

When  I  export  a good DEM, I get "Nodata" marks at all or almost all
grid points.

So  the  procedure "export data, then import them" does not return the
source data!

The  import  procedure  of  Esri  ASCII  data works correctly only for
corners data in the source file.
If  the  source  file  contains  "xllCenter...  yllcenter", then after
import the size of the grid cell changes.

Please advise me how can I export ilwis map data to Esri ASCII format.

Oleg Mironov
