I have basically the same transformration encoded below in 2 different
ways. One uses transform the other the program cs2cs. I am just
trying to convert a latlong to a different datum. It seems that I am
getting the wrong answer with Transform.
select
X( Transform( SetSRID(MakePoint(-86.123456789::double
precision,34.123456789::double
precision),4030),4267 ))::double precision from al_ent;
x
---------------
-86.123456789
-86.123456789
>cs2cs +proj=latlong +datum=NAD83 +to +proj=latlong +datum=NAD27 -f
%.12f<<EOF
> -86.123456789 34.123456789
>
> -86.123481462163 34.123361126798 -0.000032913871
