.img to .xyz format?

[Robertde_Boer]

Hi,

I just started using ArcGIS. I am going to make a model with engineering hydrodynamic software. Now I found a DEM to use, this DEM is in the format .img.

Does someone know how to convert this .img format into a .xyz format? Or another kind of format (ascii) which can be used in the
software GUI to create bathymetry and grids?
I have the ArcGIS 10.1 software installed.

Thanks,
Robert

"Raster To ASCII" (Conversion Tools).

Run the following tools
- RasterToPoint
- AddXY (add xy coordinates from the Data management tbx)

You can use the Sample tool to output z,x,y values to a DBF table, then convert that to a text file. 

Note: The answer that "nidhinkn" posted (Raster to ASCII) will _not_ work as it does not output X & Y values.
