Turns Database

The Turns Database is a simple route system for storing information about Turn Functions.

Technical Details

The routes store information about the turn function as a whole, such as the function number, the atnode, and the number of an associated project (0 if it is a function of the Base Network).

The sections themselves contain no attributes beyond those added by ArcInfo. The item turns-id is set to 1 if the section represents the from arc, or 2 if it is the to arc.

For more information about how turns are stored, please refer to Item definitions for the Turns Database and The Project Database. For more information about using route systems and dynamic segmentation, please refer to the ArcInfo documentation.
