These records (codes 4,5,6,7,14,24) are used to enter coordinate values for a station.
Note: Only the first value encountered is saved with the exception of the junction definition where a code 6 will overwrite a code 4 or 5 and a code 5 will overwrite a code 4

1 Blank
2-3 Code used to identify the type of data
4 : terrestrial or spatial (non junction)
5 : terrestrial or spatial (junction)
6 : spatial (junction)
14 : terrestrial (non junction)- stores a
constraint equation in INTCOBS
4-6 Type used to identify a class of observations (Examples)
DOP : doppler
F : doppler data adjusted in framework
S : doppler data adjusted as secondary
P : doppler data computed on precise ephemeris
B : doppler data computed on broadcast ephemeris
F : doppler station coincident with terrestrial
framework
S : doppler station coincident with terrestrial
secondary
: doppler station not coincident with
terrestrial survey
GPS : global positioning system data
LBI : long baseline interferometry data
Any 3 alpha-numerical characters can be used to
identify a class of observation
7-15 Station number used to associate the data on
this record with data on other records for the same
coordinates
16-30 Station name
31 Blank
32 Station classification (Order)
33-38 Associated network
39 Blank
40 Latitude north-south indicator (blank, N, + or S, -)
41-42 Latitude degrees
43-45 Latitude minutes
46-54 Latitude seconds (decimal required)
55 Longitude east-west indicator (blank, W, + or E, -)
56-58 Longitude degrees
59-61 Longitude minutes
62-70 Longitude seconds (decimal required)
71-79 Orthometric height (decimal required)
80 Orthometric height indicator (blank for astronomic
record)
A : from framework file
F : height expressed in feet
H : H dop determination
I : interpolated from contours
L : local computation, source unknown
M : height expressed in meters
N : NGDB (National Geodetic Data Base)
P : provincial
S : scale
T : trigonometric
blank : not evaluated
Note: except for "F", none of these indicators is used by
GHOST during the adjustment and the only valid indicators
are the ones listed above along with the digits 0 to 9.
