Pastor,
What you are asking for is called a Lambert Conformal Conic Projection with
two standard parallels. The Transverse Mercator math model programmed for
MapInfo does NOT have sufficient series terms to provide computational
precision adequate beyond 3 - 4 degrees on either side of the central
meridian. It is easy to do with the Lambert, and MapInfo will handle it
well.

Hi
I was wondering if anyone on the list has had experience
in using secant mercator projections for project grids.
What I need to do is set up a projection for a long skinny
project that crosses a number of UTM zones (ie East West),
so I thought a secant mercator projection along a line of
lattitude would suit this perpose (north south extent is minimal).
However, I'm not aware of anyone who has tried this (although I'm
sure someone has) and I'm having trouble tracking down the
parameters for such a projection.
I'm hoping that if such a projection is viable and I can get
hold of the parameters, the implementation within MapInfo will
be quite straight forward.
Any help appreciated.
Thanks
