Remarks

This class is used as the base class for line shapes such as:

LineShape
MultilineShape

It can be inherited from to create your own specialized line geometry. If you choose to do this, your new class must conform to one of the well-known text standard shapes in order for the base implementations to work properly.

Constructors

LineBaseShape()

This is the default constructor for AreaBaseShape.

protected LineBaseShape()

Remarks

This constructor simply calls the base constructor.

Methods

ConvexHull()

This method returns the convex hull of the shape defined as the smallest convex ring that contains all the points in the shape.

public RingShape ConvexHull()

Returns

RingShape

This method returns a RingShape defined as the smallest convex ring that contains all the points in the shape.

Remarks

This method is useful when you want to create a perimeter around the shape. For example if you had a MultiPolygon which represented buildings in a campus you could easily get the convex hull of the buildings and determine the perimeter of all of the buildings together. This also works with MultiPoint shapes where each point may represent a certain type of person you are doing statistics on. With convex hull you can get an idea of the regions those points are located in.

As this is a concrete public method that wraps a Core method we reserve the right to add events and other logic to pre or post process data returned by the Core version of the method. In this way we leave our framework open on our end but also allow you the developer to extend our logic to your needs. If you have questions about this please contact support as we would be happy to work with you on extending our framework.

Exceptions

InvalidOperationException

In the event you attempt to call this method on a shape which has no points, it will throw an InvalidOperationException.

ConvexHullCore()

This method returns the convex hull of the shape defined as the smallest convex ring that contains all the points in the shape.

protected virtual RingShape ConvexHullCore()

Returns

Parameters

shapeUnit GeographyUnit

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs.
