This dialog also displayed for the following data collectors: Carlson SurveCE, Microsurvey Field Genius and Thales Z-Max.
Use this option to protect the position record (SP and OC) coordinates as they are imported. If you do not protect the coordinates (default), they are recomputed by the raw data that was imported.
Use this option to update existing points in the survey with the data being imported. If an imported point has the same label as an existing point, the imported coordinates are copied to the existing point.
If this option is off (default), and an imported point has the same label as an existing point, TPC creates a new survey point for the imported point. The one exception to this is that if an imported stored point (08KI) has the same label and coordinates as an existing point, the imported point is assumed to be the same as the existing point and a new point is not created.
Insert comment records into the traverse as a Note record.
Use this option to create a traverse point for each stored point (SP) being imported. If this option is off (default), stored points are added to the survey and therefore can be accessed through the Points Manager, but are not added to the traverse created by the import.
Use this option to treat the first observation (TR) after a station record as a backsight observation. Although typically not needed for TDS, it is available should you omit the BK records.
Use this option to eliminate redundant points in the traverse created from the import.
The TDS file format includes the following records for each foresight (OC-station, BK-backsight and TR-foresight). This results in the following traverse point sequence.
1 OP
99 BS
2 SS
2 OP
1 BS
3 SS
3 OP, etc.
This option reduces this sequence to the following
1 OP
99 BS
2 FS
3 FS, etc.
This format is much cleaner to work with and is typical of how the traverse would look if you had entered the data manually.
Creates a detailed report in the Message View, showing how the file was converted. You will also see the following:
Unsupported records - displays the entire record
Every station (OC) and backsight (BK) record, even if you choose to combine them.
All comments, even if you choose not to include notes in the traverse.
Turn this option on to show unsupported records. TPC does not read the individual observations in a horizontal angle set for this format. If you don't want these to show up as unsupported records, turn this option off.
Use this option to convert horizontal circle readings to angles. TPC does this by subtracting the BS circle reading from any observations and setting the BS circle reading to zero.
Some surveyors set the BS circle to the reference azimuth of the BS. Any angles turned can be read as a direct azimuth if desired. TPC computes these observations just fine, but if you then copy data to the scrap traverse and include raw data you can loose the association of the circle reading and its original backsight. Converting from a circle reading to the resulting angle can eliminate the side effects of these actions.
If you turn this option on when exporting a RAW or RW5 file, TPC includes TR and SS records for traverse points with raw data. If a traverse point does not contain raw data, no record is written for it.
Notice in the lines shown here the TPC has included a SS record for each SP record. If you do not turn on this option, you will get just the SP records.
