Input Resection

(This functionality is available with the Input / Output module)

Allows manual input of direction observations to obtain a least squares resection solution. The observations are stored in a Field File.

The Input/Resection command is selected from the Field Transfer task.

Data which is input using this command is stored in a Field File which may then be edited using the Field Transfer/Resolve/Edit Field File command to correct any data entry errors.

The data may be reduced and transferred as objects to the data base using the Field Transfer/Resolve/Reduce Field File command.

You may use the Field file dialog box to select the data path and the name of the field file to be used for storing the observations entered.

Select the required data path by double clicking the required folder in the folders list box. Then click in the file field and key in a new field file name, or select an existing field file from the field file list box. Click the OK button to open the field file. If the selected file already exists, you may append to it or overwrite it by clicking the appropriate button when warned of the file's existence.

After selecting the field file, use the Resection dialog box for entering the observations.

In the New Point Occupied group box, click in the Point Identifier field and key in the identifier of the new point from which the directions were observed and for which the resected co-ordinates are required. You may also enter a Code and description for this point.

After entering the New Point Identifier, click the OK button to transfer focus to the sighted to group box.

With the focus in the Sighted To group box, click in the Point Identifier field and key in the identifier of the first point observed. Use the TAB key or the mouse to move to the other data fields and key in the observed values for Direction and SD (Standard Deviation). Press the ENTER key or click the OK button to record the observation in the field file. The focus will go to the Point Identifier field for entry of the next observation. After entering all observations click the Exit button to close the dialog box.
