[gdal-dev] Gdaltindex

[Jukka Rahkonen]

Hi,

I was creating tileindexes with gdaltindex from FWTools 2.2.6 on Windows
and I received strange looking error messages if I had external overviews in 
directories. So far it looks like the resulting shapefile is OK and it has
polygons for all image files. However, while it is somehow understandable
to get error messages about external overviews (named .tif.ovr) gdaltindex 
gives also errors about some .tif files. As I said, tileindex shapefiles
seem to be OK despite of all the error messages. 

My command line was like:
gdaltindex M105_WMS.shp	G:\Data\Shares\Ilmakuva2\Ilmakuvat\M105_WMS\*.tif

A few examples of the error messages follow with couple of my comments
marked with *** 

  Unable to open
G:\Data\Shares\Ilmakuva2\Ilmakuvat\
M105_WMS\FMI_2007_M105_TM35_114107D.tif, skipping.

*** This file exists, it is OK for gdalinfo, and it is included in the
resulting tileindex so it was not skipped really.

  ERROR 4:

M105_WMS\FMI_2007_M105_TM35_114111C.tif.ovr'
not recognised as a supported
file format.

*** Perhaps external overview mechanism for tiff files have made it 
necessary to make program to understand that *.tif should not include
*.tif.ovr files?
