The Data editor

The Data editor displays as tables various information related to the aerotriangulations of Aerotri. It is split into two halves, each one of them displays a different kind of information.

Top half

It shows the contents of the input files. Each page corresponds to a file, except the approximate values of projection centres and points, that are shown in two different pages but belong to the same file.

Their contents can be edited and afterwards saved to a file, clicking with the right button over the table. In contrast to the editing in any text editor it has the advantage that certain details about the file formats need not be known, but it has the disadvantage that moving through the data is usually slower.

Bottom half

It shows the residuals of the adjustment. It is an information that cannot be edited.

The first two pages display the same contents, the residuals of the photo coordinates, but orginised in different ways. In the first one they are sorted by photographs; thus, for each photograph it is shown the residuals of the points appearing in it. The page “by points”, on the other hand, displays the residuals grouped by points, showing for each point the photographs in which it appears, with its corresponding residuals.

In both cases next to the point it is indicated those coordinates that the point serves as control point (for example, ‘XY’ if it is a planimetric control point and ‘XYZ’ if it is a complete control point). An exclamation mark at the row of a point means that the point is not a control point and it has only been observed in two photographs or is an control point only measured in one photo.

The third page displays the residuals of the control points, and the last one those of GPS an inertial system observations.

The contents of the tables can be sorted regarding different criteria, clicking with the right button.

Open

There can be opened two different kind of files: input files (photographs, approximate values, points and gps/ins) and files of results (with extension bnf). The first ones are text files that can be edited in any text editor. The last ones have a particular format. As well as the results they include the name of the files that where used as input files in the adjustment, so that they can be opened in case they are found.

Right button

When clicking with the right button over any of the tables, a menu with different options is shown. The options vary for each table.

Save all and calculate

This option is offered only when the Data editor is being executed in a coordinated way with Aerotri by means of Aerotri Manager. All the tables corresponding to input files that have been modified are saved, and at Aerotri the adjustment is started, using the files indicated in the main window from Aerotri (that if nothing has been modified since the last adjustment they will be the same that those of the Data editor we have just saved).
