vgridshift: add a +multiplier={value}
2018-07-11Revert pj_units to_meters entries for US units.Charles Karney
Bletch, pj_init also decodes the to_meters field of pj_unit, but only handles plain numbers or 1/nnn, but not 1./nnn or mmm/nnn. (So the original code would have not decoded the us-in entry properly.) Probably pj_init should be changed to use the factor field instead. Alternatively pj_init should look for a "/" anywhere in the field and decode the numerator and denominator as separate doubles. This would be needed if ratios are ever to be entered directly by the user (this is the strategy used by GeographicLib). And then, of course, the functionality should be provided by a separate utility function.

2018-07-11Fix #1074. Fix unit conversion factors for geod.Charles Karney
Previously, unit conversion using atof(unit_list[i].to_meter) which gives the wrong answer with, e.g., "1/10". Now it directly uses unit_list[i].factor (e.g., 0.1). Also fix all the conversion factors for the US Surveyor units so that they are the closest doubles. E.g., the conversion factors for US feet are factor rel error old 0.304800609601219 6e-16 12/39.37 1e-16 now 1200/3937.0 5e-17 Maybe someone should check the Indian units (but it's possible that India and Pakistan have different standards).

As mentionned in #1071, it is often unclear how the offset of a vertical grid is applied.

2018-07-06Add info on errnos when PJ creation fails.Kristian Evers
This was left out when documented the various proj_create_* functions. Added proj_context_errno description as well since it was undocumented and is needed when creating PJs for a specific context.

2018-06-29Helmert: consider that xyzt.t == HUGE_VAL means t_epochEven Rouault
Currently when doing echo "2 49 0" | src/cct +proj=pipeline +ellps=GRS80 +step +proj=cart +step +proj=helmert +x=10 +y=3 +z=1 we get as a result: -nan -nan -nan inf This is due to cct initializing the xyzt.t to HUGE_VAL

2018-06-27Use proj_torad() instead of proj_todeg().Kristian Evers
Internally PROJ uses radians so of course that is what we need to convert our input coordinates to before processing with proj_trans().
