Hi,
just a syntax issue : replace +pipeline with +proj=pipeline
Even

Hi
I would like to compute the difference in a topocentric system (ENU)
from points in geocentric coordinates... with the output in millimetres.
echo 4000000.0000 300000.0000 5000001.0000 | cct +pipeline +step
+proj=topocentric +X_0=4000000.0000 +Y_0=300000.0000 +Z_0=5000000.0000
+step +proj=unitconvert +xy_in=m +xy_out=mm +z_in=m +z_out=mm
0.0000 0.6232 0.7820 inf
But that is exactly the same output if I do not do the unit conversion.
echo 4000000.0000 300000.0000 5000001.0000 | cct +pipeline +step
+proj=topocentric +X_0=4000000.0000 +Y_0=300000.0000 +Z_0=5000000.0000
0.0000 0.6232 0.7820 inf
Am I doing something wrong?
Thanks.
