Haiti used the secant case of the Lambert Conformal Conic
on the North American Datum of 1927, (Clarke 1866
ellipsoid) - This is since the early 1950's. However, I
believe this projection and associated Grid were only used
for the computation of the original Geodetic Triangulation.
This was courtesy of the U.S. Army's Inter American
Geodetic Survey formed after WWII and headquartered in the
Canal Zone. The geodetic control and photogrammetric
mapping was done by the IAGS/Army Map Service. The
military 1:50,000 topographic maps were based on the UTM
Grid, NAD 1927. If you have access to Haiti topographic
mapping, I would assume it's UTM.
I think that you will find the initials "MTU" somewhere on
the map sheets. That's "UTM" in French, and you will
probably also find the zone ("Fuseau") number identifying
the central meridian used.
I have noticed that many tourist maps throughout the
Caribbean have a "map key" Grid based on numbers and
letters that just happen to be 1-kilometer or 10-kilometer
squares for finding local points of interest. Those
squares will invariably be identical to the local Geodetic
Grid system used for that locale.
