Configuration of the Conversion

This dialog box is activated by clicking on the Configure button in format selection. It allows one to generically control of differences between point and station observations, in addition to any actions one may wish to perform should there be repetitions or inverse circle observations. Some of the formats available distinguish between different kinds of observation. In such cases, these options have no bearing on the conversion.

All options described in the dialog box can be stored in a file with a .CFG extension by pressing the Save button and subsequently recovered using the Load button.

Original total station file observations are considered point observations by default. In order for them to be considered as total station observations, the following options are available:

· Code. Observations are considered as station observations if their code is within those entered in the field. Several can be shown, separated by commas.

· Prefix. Observations are considered as station observations if their names start with one of the prefixes specified in this box. Several can be shown, separated by commas.

· Ordinal. If this option is activated, only the observations falling within the Minimum and Maximum values entered are considered as station observations. The rest are considered as point observations.

· Alphanumeric Ordinal. Observations are considered as station observations if their names are not numerical.

· Observations to Instrument Set-Ups. If this option is enabled, a preliminary analysis is performed to check the source of all the observations. Observations are considered as station observations if they are origin observations. For instance, if observations from stations 1,2 and 3 are found, the observations from stations 1 to 2 and from 1 to 3 are considered to be station observations.

· Observations from Different Instrument Set-ups. A point should not be read from several stations, since only one set of coordinates can be stored. If this option activated, these points are considered as station observations.

The reason why observations have been considered as station observations is indicated in the Check Observations dialog box’s status line

The checks conducted by the program are as follows:

· Inverse Circle. If this option is activated, the second observation is considered to be the inverse of the first one if the program finds two consecutive observations with more or less complementary vertical angles.

· Repeated Observations. If this check box is marked, observations are highlighted as repeated observations and the program takes whatever action has been specified in the Action for Repetitions section when repeated observations of a point or station are found.

The actions that may be chosen should repeated readings be found include the following:

· Save First. Only the first observation is saved. The rest are discarded.

· Save Last. The last observation found is saved. The previous ones are discarded.

· Average Observations. One observation is created from the average of all the observations.
