Chapter 4 Options
� Observations and Residuals – When selected, adjusted observations, residuals, the
standard errors and standardized residuals will be shown in the listing file. This is a
tabulation of all adjusted observations, organized by the type of observation.
Although this section may be turned off to shorten the output listing file, it is an
important part of any final report and normally should be included because it clearly
shows how much each observation was changed in the adjustment process.
� Coordinates, Sideshot Coordinates, Geodetic Positions – When these items are
selected, final adjusted coordinates, sideshot coordinates (when the job includes
sideshots) and geodetic positions (when the job is grid) will be listed in the output
listing file. When the presence of one or more of these adjusted coordinate items in
the listing file is not important, these options can be unchecked to significantly
reduce the size of the listing file.
� Convergence and Grid Factors – When selected and the job is grid, a table showing
the convergence angle, grid factor, elevation factor, and combined grid factor at each
station in the network will be created.
� Azimuths and Horizontal Distances – When selected, a table of adjusted bearings
and horizontal distances will be created between all points connected by
observations. If error propagation is performed, the table also includes relative
confidences of the azimuth and distances. This table also includes additional
connections that can be defined by using the “.RELATIVE” inline data option.
� Traverse Closures – When selected, and if observations have been entered in your
data using the Traverse data type, a summary of each unadjusted traverse closure,
along with closure precisions, will be included in the listing file.
� Standard Deviations, Error Ellipses and Relative Ellipses – When selected, these
sections will be included in the listing if error propagation is performed. Each can be
independently selected depending on what you want shown in your listing.
� Coordinate Changes from Entered Provisionals – When selected, a tabulation of the
differences between hand-entered provisional coordinates and the final adjusted
coordinates is included in your listing. This is particularly useful in deformation
studies when you are trying to determine the movement of specific stations since the
previous survey was performed. Only those stations that have explicitly hand-entered
provisional coordinates are listed in this section - not those stations whose
approximate coordinates are computed by the program.
� Coordinate Changes for Each Iteration – When selected, changes in coordinates plus
the sum of squares and changes in the sum for each iteration are shown in the output.
You would normally not include this section, but it sometimes can be useful when
debugging a problem adjustment. If an adjustment takes excessive iterations, for
example, you may want to review this section to see if coordinates in some area of
the network are having difficulty converging to a solution, or perhaps to determine if
a larger convergence value may be required in some unusual cases.
