Marco,
1. You misspelled the option for world file creation as 'TWF' which should
actually be 'TFW'.
2. The driver did report the error message correctly after processing the
creation options. There may be a bug with the debugger.

Okay, I will take that approach then. Thank you all for your help.
What specific value should I write into the .cpg? The string '65001'
or the string 'utf-8' or something else?

Hi everyone,
I understand that the first pyramid level (subimage 0) in an OVR pyramid
file is missing because this saves a lot of space compared to how RRD
pyramid files are built.
For those of you who use the pyramid files to display/zoom images, do you
rebuild the first pyramid level or do you
Hi all,
I am trying to associate my .OVR (or RRD) pyramid file with its .img
counterpart. Dealing with subimages is where it gets tricky.
As I understand it, .ovr (or .rrd) is the pyramid file for .
So that's simple enough.
However the problem is dealing with subimages. My .img file has mu

Even though the tiles are South of the equator, they are in the UTM North
coordinate system. Try
-a_srs EPSG:32601
instead of 32701, for Zone 1.

A useful resource is http://spatialreference.org/

Thanks a lot Frank and Luke.
This is the solution of my problem:
1) I built *.vrt file from ASCII file;
2) I used the command like this:

Hi Francis,
what does not portable mean? ArcMap handles UTF-8 fine, if the correct
encoding is written into the .cpg file. Recent shapelib should handle
this fine, too. If there is any problem with a specific GIS program, a
bug report for that GIS program might be the right thing to do.
Regards,
At the bottom of this page, for one:
http://resources.arcgis.com/content/kbase?fa=articleShow&d=21106
But honestly I've found hard to find information about this. I'd be
very happy to be corrected if this is not the case!
Cheers,
Francis
