This dialog determines what shape types TPC imports.

Symbol & Browse

Choose the Object file for the symbol you want to attach to any Point shapes imported into a drawing. The Symbol is not used when importing shapes into a survey.

Traverse Threshold

Enter the number of shape file records at which TPC issues a warning stating that the shape files contains a large number of records and should probably be imported into a drawing instead of the survey.

Shape files can include thousands of short polylines that define drainage lines, contours, etc. These shape files are not appropriate to be imported into the survey via the Points Manager or Traverse View because each Polyline shape creates a traverse. You should import these shape files into a drawing, then convert the appropriate polyline objects to traverses.

Starting Point Label & Next Label

When importing shapes into a survey, the first shape is assigned this point label. This label is then incremented for additional shapes.

Choose the Next Label button to find the next available label.

Point Description

When importing shapes into a survey, this description is copied to each created survey point.

Coordinate System

If the shape file you are importing has a corresponding projection file (.prj), TPC will use that information to render the imported shapes.

The Coordinate System of a shape file is defined in it's corresponding projection file (.prj). If one exists, TPC parses it, looking for either a PROJCS tag, indicating a Projected Coordinate System or a GEOGCS tag, indicating a Geographic Coordinate System.

In the absence of a projection file, TPC evaluates the extents of the shapes on import and prompts you to read them as geographic positions if their extents are within the range of -360 to 360 (values of latitude and longitude in degrees). Coordinates for these geographic positions are generated using the current CRS of the survey.
