extent is invalid for geotiff

[Ed McNierney]

John -

No, there isn't any preferred method.  A GeoTIFF will hold projection,
datum, and bounding box information in a way that can be read by
MapServer.  As long as the GeoTIFF is created properly (i.e. you can't
leave out the projection) the coordinate formats used don't matter.

Ed,

Thank you, that worked.  I seems obvious now when I look back at the
documentation.

Perhaps someone can answer another question.  In creating geotiffs, is
there a preferred way of specify coordinates (degrees, UTM, etc)  so
that the image will work well with MapServer?

Thanks again for the response,
John
