InputShorelines: Input shorelines vector segment
Specifies the input vector segment that describes the shorelines for which transects are to be made.
InputBaseline: Input baseline vector segment
Specifies the baseline input vector segment that defines the normal direction in which transects are to be made.
Output: Output transects vector segment
Specifies the output vector segment to receive the generated transects.
Field containing the Year
Specifies a field, associated with each input vector segment, to use as the year marker.
Interval Between Perpendicular Transects
Specifies, in ground units, the interval to use for the automated transects.
Query String for Selecting Shorelines
Optionally specifies a vector query expression used to selectively use vectors that satisfy the search criteria.
"year < 1970"
TRANSEC uses only vectors that have "year" values of less than 1970.
Method for Computing New Shorelines
Specifies the method to use to compute a new shoreline.
Years of Erosion/Erosion Rate
If STR2 (Method for Computing New Shoreline) is AVERAGE or ENDPOINT, specifies the number of years of erosion to simulate.
If STR2 is FIXED, specifies the total erosion.
Report
Specifies where to direct the generated report.

Transects are created along the base line vectors every NUM1 units. Should a transect interval span an interior vertex of the base line, a bisector is created for the transect at the interior vertex. In all other cases, a transect perpendicular to the baseline is created. A minimum of two line segments are created for each line segment.
A vertex is created where each transect crosses a shore boundary. A shore may cross a transect more than once and all vertices are recorded. If several shoreline layers are specified, vertices are added sequentially to each transect for each shoreline segment.
A record is created with each transect, with each field denoting the distance between the baseline and shoreline. Each field will be marked with the values obtained from the field specified by FLDNME (Field Containing the Year).
In the case of a shore boundary that crosses the transect multiple times, the closest one to the baseline is recorded.
Where a shoreline does not cross the transect, the distance recorded will be -1.
If the specified Method for Computing New Shorelines (STR2) is not NONE, a predicted shoreline will also be created based on either calculated or provided erosion rates.
