respect to different data type entries, I have some considerations. The
error raised by gdalbuildvrt made me wonder about my data and then with
your help I discovered what was wrong with them. On the other hand,

What kind of safety do you mean?
AFAICT, it does not sound sensible anyway.
Use of NaN would give unreliable results, by definition

Hi Even,
if I understand well the new SQLite style dialect you've
developed for OGR is mainly based on a VirtualTable.

Hello folks,
Can gdaltindex create a sqlite db instead of a shapefile.

And you could add SQLite to the Wiki as well (if it works).

Thanks for the details.
We have tried taking a working shp tileindex file and converting it using
