Remarks:

Registering allows you to take a geometric shape generated in a planar system and attach it to the ground in a Geographic Unit.

A common scenario is integrating geometric shapes from external programs (such as CAD software or a modeling system) and placing them onto a map. You may have the schematics of a building in a CAD system and the relationship between all the points of the building are in feet. You want to then take the CAD image and attach it to where it really exists on a map. You would use the register method to do this.

Registering is also useful for scientific modeling, where software models things such as a plume of hazardous materials or the fallout from a volcano. The modeling software typically generates these models in a fictitious planar system. You would then use the register to take the abstract model and attach it to a map with real coordinates.

Overriding:

Please ensure that you validate the parameters being passed in and raise the exceptions defined above.

TranslateByOffsetCore(Double, Double, GeographyUnit, DistanceUnit)

This method moves the base shape from one location to another based on an X and Y offset distance.

protected void TranslateByOffsetCore(double xOffsetDistance, double yOffsetDistance, GeographyUnit shapeUnit, DistanceUnit distanceUnit)

Parameters

xOffsetDistance Double

        This is the number of horizontal units of movement in the DistanceUnit specified by
        the distanceUnit parameter.

yOffsetDistance Double

        This is the number of horizontal units of movement in the DistanceUnit specified by
        the distanceUnit parameter.

shapeUnit GeographyUnit
This is the GeographicUnit of the shape you are performing the operation on.

distanceUnit DistanceUnit
This is the DistanceUnit you would like to use as the measurement for the move. For example, if you select miles as your distanceUnit, then the xOffsetDistance and yOffsetDistance will be calculated in miles.

Exceptions

ArgumentOutOfRangeException
If you pass in a distanceUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

ArgumentOutOfRangeException
If you pass in a shapeUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

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

Remarks:

This method moves the base shape from one location to another based on an X and Y offset distance. It is important to note that with this overload the X and Y offset units are based on the distanceUnit parameter. For example, if your shape is in decimal degrees and you call this method with an X offset of one and a Y offset of one, you're going to move this shape one unit of the distanceUnit in the horizontal direction and one unit of the distanceUnit in the vertical direction. In this way, you can easily move a shape in decimal degrees five miles to on the X axis and 3 miles on the Y axis.

Overriding:

Please ensure that you validate the parameters being passed in and raise the exceptions defined above.

TranslateByDegreeCore(Double, Double, GeographyUnit, DistanceUnit)

This method moves the base shape from one location to another based on a direction in degrees and distance.

protected void TranslateByDegreeCore(double distance, double angleInDegrees, GeographyUnit shapeUnit, DistanceUnit distanceUnit)

Parameters

distance Double

        The distance is the number of units to move the shape using the angle specified.
        The distance unit will be the DistanceUnit specified in the distanceUnit parameter. The
        distance must be greater than or equal to 0.

angleInDegrees Double
A number between 0 and 360 degrees that represents the direction you wish to move the shape with zero being up.

shapeUnit GeographyUnit

        This is the GeographicUnit of the shape you are performing the operation
        on.

distanceUnit DistanceUnit

        This is the DistanceUnit you would like to use as the measurement for the move. For
        example, if you select miles as your distanceUnit, then the distance will be calculated
        in miles.

Exceptions

ArgumentOutOfRangeException
Passing an invalid angleInDegrees which is not between 0 and 360 will throw an ArgumentOutOfRangeException.

ArgumentOutOfRangeException
If you pass in a shapeUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

ArgumentOutOfRangeException
If you pass in a distanceUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

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

ArgumentOutOfRangeException
Passing an invalid distance which is not greater than or equal to 0 will throw an ArgumentOutOfRangeException.

Remarks:

This method moves the base shape from one location to another based on angleInDegrees and distance parameter. It is important to note that with this overload the distance units are based on the distanceUnit parameter. For example, if your shape is in decimal degrees and you call this method with a distanceUnit in miles, you're going to move this shape a number of miles based on the distance and the angleInDegrees. In this way, you can easily move a shape in decimal degrees five miles to the north.

If you pass a distance of 0, then the operation is ignored.

Overriding:

Please ensure that you validate the parameters being passed in and raise the exceptions defined above.

RotateCore(PointShape, Double)

This method rotates the shape a number of degrees based on a pivot point.

protected void RotateCore(PointShape pivotPoint, double degreeAngle)

Parameters

pivotPoint PointShape
The pivotPoint represents the center of rotation.

degreeAngle Double
The number of degrees of rotation required from 0 to 360.

Exceptions

ArgumentNullException
If you pass a null as the pivotPoint, we will throw an ArgumentNullException.

ArgumentOutOfRangeException
Passing an invalid degreeAngle which is not between 0 and 360 will throw an ArgumentOutOfRangeException.

InvalidOperationException
In the event you attempt to call this method on a shape which is not valid, it will throw an InvalidOperationException.

Remarks:

This method rotates the shape by a number of degrees based on a pivot point. By placing the pivot point in the center of the shape, you can acheive in-place rotation. By moving the pivot point outside of the center of the shape, you can translate the shape in a circular motion. Moving the pivot point further away from the center will make the circular area larger.

Overriding:

Please ensure that you validate the parameters being passed in and raise the exceptions defined above.

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

ArgumentOutOfRangeException
If you pass in a shapeUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

Remarks:

This method returns point of the current shape that is closest to the target shape. It is often the case that the point returned is not a point of the object itself. An example would be a line with two points that are far apart from each other. If you set the targetShape to be a point midway between the points but a short distance away, the method would return a point that is on the line, but not one of the two points that make up the line.

GetDistanceToCore(BaseShape, GeographyUnit, DistanceUnit)

This method computes the distance between the current shape and the targetShape.

protected double GetDistanceToCore(BaseShape targetShape, GeographyUnit shapeUnit, DistanceUnit distanceUnit)

Parameters

targetShape BaseShape
The shape you are trying to find the distance to.

shapeUnit GeographyUnit
This is the GeographicUnit of the shape you are performing the operation on.

distanceUnit DistanceUnit

        This is the DistanceUnit you would like to use as the return value. For example,
        if you select miles as your distanceUnit, then the distance will be returned in
        miles.

Returns

Double

        The return type is the distance between this shape and the targetShape in the
        GeographyUnit of the shape.

Exceptions

ArgumentException
If you pass in a targetShape which does not have any points, we will throw an ArgumentException.

ArgumentNullException
If you pass a null as the targetShape, we will throw an ArgumentNullException.

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

ArgumentOutOfRangeException
If you pass in a shapeUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

ArgumentOutOfRangeException
If you pass in a distanceUnit that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

GetWellKnownTextCore(Int32)

This method returns the well-known text representation of this shape.

protected string GetWellKnownTextCore(int vertexCountInQuarter)

Parameters

vertexCountInQuarter Int32

        This parameter specifies how many points will make up each quarter of the
        ellipse.

Returns

String
This method returns a stringthat represents the shape in well-known text.

Exceptions

InvalidOperationException
In the event you attempt to call this method on this shape which has invalid upper left and lower right points, it will throw an InvalidOperationException.

ArgumentOutOfRangeException
Passing an invalid vertexCountInQuarter which is not greater than 0 will throw an ArgumentOutOfRangeException.

Remarks:

This method returns a string that represents the shape in well-known text. Well-known text allows you to describe geometries as a string of text. Well-known text is useful when you want to save a geometry in a format such as a text file, or when you simply want to cut and paste the text between other applications. An alternative to well-known text is well-known binary, which is a binary representation of a geometry object. We also have methods that work with well-known binary. Below are some samples of what well-known text might look like for various kinds of geometries.

ValidateCore(ShapeValidationMode)

This method returns a ShapeValidationResult based on a series of tests.

protected ShapeValidationResult ValidateCore(ShapeValidationMode validationMode)

Parameters

validationMode ShapeValidationMode

        This parameter determines whether the test is simple or advanced. In some cases, the
        advanced tests can take some time. The simple test is designed to always be
        fast.

Returns

ShapeValidationResult

        This method returns a ShapeValidationResult based on a series of
        tests.

Exceptions

ArgumentOutOfRangeException
If you pass in a validationMode that is not defined in the enumeration, it will throw a ArgumentOutOfRangeException.

Remarks:

We use this method, with the simple enumeration, internally before doing any kind of other methods on the shape. In this way, we are able to verify the integrity of the shape itself. If you wish to test things such as whether a polygon self-intersects, we invite you to call this method with the advanced ShapeValidationMode. One thing to consider is that for complex polygon shapes this operation could take some time, which is why we only run the basic, faster test. If you are dealing with polygon shapes that are suspect, we suggest you run the advanced test.
