<div>Hi</div>
<div><br>
</div>
<div>I would like to compute the difference in a topocentric
system (ENU) from points in geocentric coordinates... with the
output in millimetres.</div>
<div><span style="font-family:monospace"><br>
</span></div>
<div><span style="font-family:monospace">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</span></div>
<div><span style="font-family:monospace"> 0.0000
0.6232 0.7820 inf</span></div>
<div><br>
</div>
<div>But that is exactly the same output if I do not do the unit
conversion.</div>
