Hi, just for summarize messages about formats and options:

- MapInfo index file - IND files (Mentioned by Jody Garnett):
C/C++ code in OGR:

- Xbase index files - CDX, IDX, MDX, NTX, NDX files:

Asunto: Re: [Geotools-devel] Voting for
"Implement-a-pure-java-Dbase-indexing-to-optimize-shapefile-access" proposal
Looking around the internet very little shape format attribute indexes can be
found and if, they are product-specific (e.g. atx). An alternative seems to be
a standard dbase index format like the one Alvaro used. Looking around for
possible formats, I came to the site http://web.tiscali.it/SilvioPitti/. NDX
and MDX seem to be the most often used index format in connection with dbase
files (a lot of products supporting dbase files can at least read these index
formats, but it is hard finding free programs with write access). The xBaseJ
project (http://xbasej.sourceforge.net/) has read and write access to these
formats in Java code under LGPL. Maybe this could be a starting point?
