Data format problem - GDFOUT and SIFP

[Zhonghai Wang]

Hi folks,

I've got some data today from Navteq, It's weird that i cannot open it with
the GIS software I have, i thought i may open it with OGR/GDAL,
unfortunately, I did not make it. I know that this problem is not about
MapServer, since the guys here are most GIS gurus, i think maybe someone
here can help me figure out how to open them or translate them into a
well-known GIS format.

The data has the file extension: GDFOUT and SIFP

Hope that you guys can help me.

Kind Regards

Zhonghai
