Chapter 5 Preparing Input Data
INLINE OPTION: .MEASURED [Bearing] [Distance] [Angle] [Direction]
.GRID [Bearing] [Distance] [Angle] [Direction]
These options are used only for “Grid” projects. When preparing data for grid jobs, the
“.MEASURED” and “.GRID” inline options may be used to change the meaning of a
type of observation.
By default, entered bearings or azimuths are assumed to be “grid” values. Similarly,
entered distances, angles and directions are assumed to be measured values, i.e. observed
in the field. During an adjustment, the program applies grid corrections to “measured”
observations and no corrections to “grid” observations.
The keywords BEARING, DISTANCE, ANGLE and DIRECTION may be used with
these inline options to indicate which observations types you want to redefine.
For example, the inline option below specifies that all subsequent bearings should be
interpreted as measured (geodetic) bearings. The program will apply grid corrections to
these bearings (t-T and convergence), and the resulting adjusted bearings will be shown
in the output listing with their own headings indicating they are measured geodetic.
.MEASURED BEARING #following bearings are measured geodetic
B 21-22 N33-44-55.78E
B 33-37 S22-35-11.84W
B etc...
.GRID BEA #to change back to grid if necessary
One or more of the keywords may be placed on a single option line. For example, if you
are combining measured field observations with “grid” values from an existing map, you
might prepare your 2D data as shown in the example below. Angle and distance
observations you are “creating” from the map are defined as “grid” using the inline
option, and therefore no grid corrections will be applied to them.
M 52-51-53 133-23-55 143.243 #default is measured
M 53-52-54 97-44-31 135.981
.GRID ANG DIST #change to grid mode
M 78-74-75 120-27-56 76.50
M 78-74-77 102-44-34 100.00
A 74-73-85 91-02-53
D 74-82 255.25
.MEAS ANG DIST #back to measured mode
M 65-62-94 112-22-33 234.27
etc...
Note that when you specify distances as “grid” distances, they must be entered as
horizontal distances. A “grid slope distance” doesn’t make any sense!
