Chapter 4 Options<br />

Observations and Residuals – When selected, adjusted observations, residuals, the<br />

standard errors and standardized residuals will be shown in the listing file. This is a<br />

tabulation of all adjusted observations, organized by the type of observation.<br />

Although this section may be turned off to shorten the output listing file, it is an<br />

important part of any final report and normally should be included because it clearly<br />

shows how much each observation was changed in the adjustment process.<br />

Coordinates, Sideshot Coordinates, Geodetic Positions – When these items are<br />

selected, final adjusted coordinates, sideshot coordinates (when the job includes<br />

sideshots) and geodetic positions (when the job is grid) will be listed in the output<br />

listing file. When the presence of one or more of these adjusted coordinate items in<br />

the listing file is not important, these options can be unchecked to significantly<br />

reduce the size of the listing file.<br />

Convergence and Grid Factors – When selected and the job is grid, a table showing<br />

the convergence angle, grid factor, elevation factor, and combined grid factor at each<br />

station in the network will be created.<br />

Azimuths and Horizontal Distances – When selected, a table of adjusted bearings<br />

and horizontal distances will be created between all points connected by<br />

observations. If error propagation is performed, the table also includes relative<br />

confidences of the azimuth and distances. This table also includes additional<br />

connections that can be defined by using the “.RELATIVE” inline data option.<br />

Traverse Closures – When selected, and if observations have been entered in the data<br />

using the Traverse data type, a summary of each unadjusted traverse closure, along<br />

with precisions, will be included in the listing file.<br />

Standard Deviations, Error Ellipses and Relative Ellipses – When selected, these<br />

sections will be included in the listing if error propagation is performed. Each can be<br />

independently selected depending on what you want shown in your listing.<br />

Coordinate Changes from Entered Provisionals – When selected, a tabulation of the<br />

differences between hand-entered provisional coordinates and the final adjusted<br />

coordinates is included in your listing. This is particularly useful in deformation<br />

studies when you are trying to determine the movement of specific stations since the<br />

previous survey was performed. Only those stations that have explicitly hand-entered<br />

provisional coordinates are listed in this section - not those stations whose<br />

approximate coordinates are computed by the program.<br />

Coordinate Changes for Each Iteration – When selected, changes in coordinate<br />

values will be shown in the output listing file for each iteration. This can sometimes<br />

be useful while debugging a problem adjustment. Normally, you will not want to<br />

include this section since it causes the listing to become substantially longer,<br />

especially if the adjustment takes several iterations to complete.<br />
