CanCalculateCoordinates Method

In This Topic

Determines if coordinates can be calculated for the traverse using COGO.

Syntax

Visual Basic (Declaration)
C#

Public Function CanCalculateCoordinates() As Boolean

public bool CanCalculateCoordinates()

Return Value

True if the coordinates can be calculated.

Remarks

The traverse is well defined if the following is true - there must be at least 1 course in the traverse; the first course cannot be defined by a tangent curve or an angle/distance line. In addition in order to calculate coordinates, the traverse should also have a StartPoint defined.

It is important to call this method prior to CalculateCoordinates to ensure that coordinates can be calculated.

Example

Calculating Coordinates

var startPoint = MapPointBuilderEx.CreateMapPoint(7500500.0, 445900.0, spatialReference);
travParcel.StartPoint = startPoint;
      
// The geometry of the features created is affected by the ground to grid correction.
// This correction is also assigned to the traverse and in the following code the
// active map's ground to grid correction is used.
var g2gCorrection = map?.GetDefinition()?.GroundToGridCorrection;
if (g2gCorrection != null)
{
  travParcel.UseGroundToGridCorrections = true;
  travParcel.GroundToGridCorrection = g2gCorrection;
}
else
  travParcel.UseGroundToGridCorrections = false;

// calculate coordinates 
if (travParcel.CanCalculateCoordinates())
{
  var coords = travParcel.CalculateCoordinates();
  var sb = new StringBuilder();
  sb.AppendLine("Calculated Coordinates:");
  foreach (var coord in coords)
  {
    sb.AppendLine($"{coord.X:F2}, {coord.Y:F2}");
  }
}
