Note : You can also explicitly check the spatial reference by using IClone::IsEqual

Example:

//To check spatial reference efficiently
IPoint pointIn = null;
IPointCollection ptColl = null;
ISpatialReference pSpatialReferenceOfCollection = null;

//The next line will not do anything if the two projections are equal
pointIn.project(pSpatialReferenceOfCollection);
ptColl.updatePoint( 1, pointIn);

Description

SetEmpty returns the Geometry to its original initialization state by releasing all data referenced by the Geometry.

Remarks


Use the SetEmpty method to clear geometries and release memory. For example, a polygon with 100 rings will have an internal array of 100 pointers to ring objects. That array will go away and Release will be called on each ring. If that polygon had the only reference on those rings, then they'll go away, which releases all their segments, which may also then go away.

Description

Returns the unique Envelope that binds the Geometry object. This is the smallest Envelope that Contains the object.

Remarks

Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.

project

public void project(ISpatialReference newReferenceSystem)
             throws IOException,
                    AutomationException
Projects this geometry into a new spatial reference.

Description

To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.

A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.

The Project method must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometry types.

If a geometry is projected to a projected coordinate system that can't represent the geographic area where the geometry is located (or if trying to move an xy coordinate from outside the projected coordinate system back into geographic), the geometry will be set to empty.

Remarks

Note: This method can only be called upon the top level geometries (Points, Multipoints, Polylines and Polygons). If the from/to spatial references have different geographic coordinate systems, the Project method looks for a GeoTransformationsOperationSet. If the set of Geotransformations is present in memory, Project will use it to perform a geographic/datum Transformation. To use a specific geotransformation, use the IGeometry2::ProjectEx method.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
project in interface IGeometry
Parameters:
newReferenceSystem - A reference to a com.esri.arcgis.geometry.ISpatialReference (in)

Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.

Remarks

SnapToSpatialReference rounds all coordinates to the resolution defined by the geometry's spatial reference system. This has a similar effect on the geometry as storing the geometry in a Geodatabase.

Remarks

GeoNormalize acts on geometries whose geographic system coordinates are below -180 degrees longitude or over +180 degrees longitude or on geometries that span the +-180 degrees longitude.
This method requires the geometry to have a valid spatial reference (geographic or projected coordinate system).

              throws IOException,
                     AutomationException
Same as Project, but with additional parameter projectionHint.

Description

To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.

A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.

The projectionHint parameter contains information about whether a geometry will cross the coordinate system horizons. If it doesn't, parts of the code that check this and intersect the geometry with the horizons can be omitted. This can dramatically improve performance. Use ISpatialReference3::ProjectionHint to initialize this parameter.

                            AutomationException
Deprecated. This method uses C style arrays which are not supported in the ArcGIS API for Java. It is replaced by GeometryEnvironment.replaceSegments(com.esri.arcgis.geometry.ISegmentCollection, int, int, com.esri.arcgis.geometry.ISegment[]).

Removes and inserts from segments. This method is intended for internal use only.

Description

Removes a specified number (goingAway) of Segments from a Segment Collection starting at a given index and replaces them (starting at the same index) with a specified number (comingIn) of Segments from an array of Segments.

Remarks

ReplaceSegments will return an error ("The index is either too large or too small") if the inputs are inconsistent. For example, specifying index = 4 on a polyline with only 2 segments.

On multipart geometry, segments cannot be replaced on more than one part at the time. For example, an error (("The index is either too large or too small") is returned on a polyline with two parts containing three segments each when specifying index= 2, incoming= 2, removal= 2. The error is returned because the first part doesn't contain enough segments to remove two segments starting at index = 2. This behavior is enforced for performance reasons. Please see the example.

                 throws IOException,
                        AutomationException
Adds a reference to the input geometry either at the end, or before, or after the specified index.

Remarks

When applying the AddGeometry method give either the before or after index and not both. Adding a Geometry to the collection as the first one is done by setting the before index as 0.

The spatial reference of the GeometryCollection is transferred (objects projected if necessary) to any objects added to it. However the spatial reference of the added geometry is not transferred to the GeometryCollection. Always make sure to set the spatial reference on the object GeometryCollection prior to add other geometries to it to avoid creating invalid geometry. For example, adding geometry objects to a GeometryBag that doesn't have a well-defined spatial reference will set an undefined spatial reference to all the objects added to the bag. Using this GeometryBag may cause unexpected behavior with the ITopologicalOperator::ConstructUnion method.

                                  AutomationException
Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.

Description

Finds the Point on the specified extended curve nearest to the input point and the distance between those points. Also returns information about the side of the curve the input point is on as well as the distance along the curve that the nearest point occurs.

Remarks

AsRatio is an input parameter that only affects the DistanceAlongCurve

distanceFromCurve is an output parameter that represents the minimum distance between the curve and the input point.

DistanceAlongCurve is an output parameter that represents the distance between the Frompoint of the input curve and the returned point on the curve.

                        throws IOException,
                               AutomationException
Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).

Description

ReverseOrientation changes the direction of the curve without changing the spatial position of the curve. The From Point and To Point of each Segment in each part of the curve are interchanged.

Remarks

The ReverseOrientation method works the same way as the Arcedit FLIP command. It reverses the order of the vertices in the Curve.

Caution should be taken in using ReverseOrientation on Polygons. Since ReverseOrientation changes the direction of each Ring within the Polygon, all Exterior Rings become Interior Rings and vice versa.

densify

             throws IOException,
                    AutomationException
Converts this polycurve into a piecewise linear approximation of itself.

Description

Converts Polycurve into a Polycurve composed of Line segments with length maxSegmentLength (or less) that are within maxDeviation of the original polycurve. If maxDeviation = 0, maxDeviation is ignored and Line segments with length maxSegmentLength are constructed with vertices laying on the original curve. All of the segments in the final polyline will be Lines.

Remarks

If the maxSegmentLength is negative IGeometryEnvironment::AutoDensifyTolerance is used. IGeometryEnvironment::AutoDensifyTolerance default value is 0. This value can be explicitly set via IGeometryEnvironment::AutoDensifyTolerance.

If the maxDeviation is negative IGeometryEnvironment::DeviationAutoDensifyTolerance is used. The default value is 2*XYResolution * 100 (2/XYUnits * 100). This value can be explicitly set via IGeometryEnvironment::DeviationAutoDensifyTolerance.

In order to avoid the creation of too many segments, the geometry system uses a maxdeviation = 2*xyResolution * 100 as default value if maxSegmentLength is 0 and the maxDeviation is 0.

If the maxDeviation is positive but smaller than 2*XYResolution of the spatial reference then the maxDeviation used is 2*XYResolution * 100

NOTE: The default values given in this topic are subject to change without notice. If specific values want to be maintained we recommend using the methods on IGeometryEnvironment to set those explicitly.

The start and end points are always honored and remain the same as for the original feature.

Generalizes this polycurve using the Douglas-Poiker algorithm.

Description

Generalizes each part of a Polycurve into a generalized collection of Line segments. Generalize performs a Douglas-Poiker Generalization algorithm with a specified maximum offset tolerance given as input. For Line segments, the Generalized output is a subset of the original input vertices. For non-Linear segments, the Generalized output contains points along all parts of the curve, not necessarily only the vertices.

Remarks

For polycurve with non-linear segments, the output curve may contain more vertices than the input curve, but all output segments will be linear.

weed

public void weed(double maxAllowableOffsetFactor)
          throws IOException,
                 AutomationException
Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.

Description

Weed Generalizes each part of a Polycurve into a generalized collection of Line segments. Weed performs a Douglas-Poiker Generalization algorithm with a specified multiple of the internal tolerance given as input. For Line segments, the Generalized output is a subset of the original input vertices. For non-Linear segments, the Generalized output contains points along all parts of the curve, not necessarily only the vertices.

Remarks

For polycurve with non-linear segments, the output curve may contain more vertices than the input curve, but all output segments will be linear.

Weed(X) = Generalize(X * InternalTolerance)

smooth

public void smooth(double maxAllowableOffset)
            throws IOException,
                   AutomationException
Converts this curve into a smooth curve containing only Bezier curve segments.

Description

Converts the Polycurve into a Polycurve containing only BezierCurve segments. If the maxAllowableOffset parameter is zero, each segment of the input Polycurve becomes a separate Bezier curve. If maxAllowableOffset if greater than zero, the polycurve is generalized first by the Douglas-Poiker method using the maxAllowableOffset value. Bezier curves are then created for each of the remaining segments. The created BezierCurve polycurve is an approximation of the original polycurve. At each vertex, the adjoining BezierCurves have complementary tangents which creates a continuous (smooth) transition between segments.

As an alternative, compare IConstructCurve2::ApproximateByBeziers.

densifyByAngle

                    throws IOException,
                           AutomationException
Converts this polycurve into a piecewise linear approximation of itself. Vertices are introduced at points where the included angle between tangents at those point is maxAngleDeviation.

Description

Converts a Polycurve into a Polycurve composed of Line segments with length maxSegmentLength (or less) that are within maxDeviation of the original polycurve. If maxDeviation = 0, maxDeviation is ignored and Line segments with length maxSegmentLength are constructed with vertices located on the original curve. All of the segments in the final polyline will be Lines. The maxDeviation is an angle in radians.

Remarks

If the maxSegmentLength is negative IGeometryEnvironment::AutoDensifyTolerance is used. IGeometryEnvironment::AutoDensifyTolerance default value is 0. This value can be explicitly set via IGeometryEnvironment::AutoDensifyTolerance.

If the maxDeviation is negative IGeometryEnvironment::AngularAutoDensifyTolerance is used. The default value is Pi / 18.0. That value can be explicitly set via IGeometryEnvironment::AngularAutoDensifyTolerance.

In order to avoid the creation of too many segments, the geometry system uses a maxDeviation = 2*XYresolution * 100 (or 2/XYUnits * 100) as the default value if maxSegmentLength is 0 and the maxDeviation is 0.

The maximum number of segments that can be produced is 2000, an external user cannot modify that value.


NOTE: The default values given in this topic are subject to change without notice. If you have specific values that you want to be maintained, we recommend using the methods on IGeometryEnvironment to set them explicitly.

The start and end points are always honored and remain the same as for the original feature.

                     throws IOException,
                            AutomationException
Densifies and reshapes existing segments so that the output segments follow the shortest ground path connecting input vertices. maxSegmentLength is in the units of the axis of the underlying spheroid of this polyline's gcs (usually meters).

Description

The GeodesicDensify method modifies a polyline or polygon by inserting vertices. The original geometry is interpreted as a sequential collection of "stops" on the Earth's surface. The inserted vertices define the shape of the shortest ground path connecting those stops. The geometry must be associated with a geographic coordinate system.

The maxSegmentLength parameter is in the units (usually meters) of the semi-major axis of the coordinate system's ellipsoid. The minimum allowable value for this parameter is 1/10,000 of the length of the semi-major axis. This minimum value will be used for densification if the input value of maxSegmentLength is less than that.

Remarks

The image below shows the results of applying the GeodesicDensify method to a polyline representing a flight path with stops in Honolulu and Los Angeles. The original polyline is modified by adding additional segments that identify the shortest ground distance between these locations.

Removes zero length segments (zero in 2 dimensions), merges parts at endpoints that only connect to each other, reorients segments that are pointing against the prevailing orientation for a part.

Description

Performs a partial simplification of the Polyline to ensure necessary consistency for a valid Network but not true topological simplicity. SimplifyNetwork performs the following alterations to the base Polyline:

1) Deletes empty and zero length segments.
2) Removes empty parts.
3) Makes segment orientation mutually consistent. Ensures that the following FromPoints and preceding ToPoints of connected segments are equal.
4) Creates new parts for discontiguous segments or segments with different attributes.
5) Merge parts where exactly two parts share an endpoint.
6) For a pair of segments in a part that share an endpoint such that one segment has NaN attributes and the other has non-NaN attributes, assign the non-NaN attributes of one to the corresponding NaN slots of the other.

Remarks

It is possbile for network features to have an inconsistent geometry requiring simplification, for example, a network edge can be a multipart feature whose parts share an endpoint. To correct the feature's geometry, set IsKnownSimple to False and call SimplifyNetwork on the feature to correct the inconsistency.

                               AutomationException
Updates Ms along the shortest path between the specified endpoints. The interpolation ratio is determined by the input ms and euclidean distance along that path. The update method is given as a combination of esriGeometryUpdateMEnum values.

Remarks

The updateHow argument is given as a combination of esriGeometryUpdateMEnum values. When combining multiple values, the bitwise Or operator should always be used. This assures an error-free combination of the values (as long as the attempted combination is valid). Do not use the addition operator (+) to combine the values as unexpected results may occur.

For example, to interpolate between the input points and to extrapolate before and after the input points, you would use 7, which equates to: esriGeometryInterpolate OR esriGeometryExtrapolateBefore OR esriGeometryExtrapolateAfter

                                           AutomationException
Calibrates Ms of existing vertices using new Ms from the input points and the shortest path distances along the polyline between those points. The update method is given as a combination of esriGeometryUpdateMEnum values.

Remarks

The updateHow argument is given as a combination of esriGeometryUpdateMEnum values. When combining multiple values, the bitwise Or operator should always be used. This assures an error-free combination of the values (as long as the attempted combination is valid). Do not use the addition operator (+) to combine the values as unexpected results may occur.

For example, to interpolate between the input points and to extrapolate before and after the input points, you would use 7, which equates to: esriGeometryInterpolate OR esriGeometryExtrapolateBefore OR esriGeometryExtrapolateAfter. A value of 0 will only split the input polyline and assign the Ms value to the new created vertex. If an input point has the same X (or projected to the same X) as an existing vertex the Ms value of the existing vertex will be updated.

Note : The "After" and "Before" for the updateHow parameter is define by the order of the points in the multipoints. Ex : If the points are define from left to right the "Before" will be at the left of the first point and the "After" will be at the right of the last point.

The cutoffDistance parameter is an input Double that represents the distance from the polyline from where points are not considered anymore as being valid calibration points.

The following picture demonstrates graphically the method behavior. A updateHow paramater of 7 has been used.

esriGeometryInterpolate = 0001 (1)
esriGeometryExtrapolateBefore = 0010 (2)
esriGeometryExtrapolateAfter = 0100 (4)

isSimple

public boolean isSimple()
                 throws IOException,
                        AutomationException
Indicates whether this geometry is known (or assumed) to be topologically correct, after explicitly determining this if the geometry is not already known (or assumed) to be simple.

Description

Returns TRUE if the geometry is topologically Simple (refer to the discussion for the Simplify method). If the geometry is not Simple, it may be necessary to call Simplify to enforce topological consistency. Editing a geometry can change the IsSimple state of the geometry.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

The xy cluster tolerance value of the geometry's associated spatial reference is used by this method. If the goal of this method is to determine if a geometry can be persisted in an sde (or other integer-based) layer without alteration, you may wish to use the minimum xy cluster tolerance value (ISpatialReferenceTolerance::SetMinimumXYTolerance) before applying this method (don't forget to set it back).

This method does not support GeometryBags.

isKnownSimple

public boolean isKnownSimple()
                      throws IOException,
                             AutomationException
Indicates whether this geometry is known (or assumed) to be topologically correct.

Description

Returns TRUE when the geometry is aware that it is Simple. IsKnownSimple may return FALSE even if the geometry is simple as long as the geometry is not aware of its IsSimple state. Calling either IsSimple or Simplify makes the IsSimple state known to the geometry. Topologically altering the geometry makes the IsKnownSimple state FALSE until the IsSimple state is again checked.

Remarks

Here is the status of the IsKnownSimple flag in some common situations:


IsKnownSimple = 'False'
- A non-empty newly created geometry. For example, creating a polygon using IPointCollection sets the flag IsKnownSimple = 'false' on that geometry.
- Geometry after projection (IGeometry::Project )
- Geometry after generalization (IPolycurve::Generalize ) or smoothing(IPolycurve::Smooth )
- …

IsKnownSimple = 'True'
- A geometry coming directly from a feature class
- An empty geometry
- Output geometry of any method on ITopologicalOperator
- …

simplify

public void simplify()
              throws IOException,
                     AutomationException
Makes this geometry topologically correct.

Description

Simplify permanently alters the input geometry, making its definition "topologically legal" with respect to its geometry type:


The XY tolerance property of the geometry's associated spatial reference is used during the simplify operation for polylines and polygons.

Remarks

This method first looks at the ITopologicalOperator::IsKnownSimple flag before starting processing. If the flag is 'true' then operation is interrupted and the geometry is considered simple. If the flag is 'false' then the geometry consistency is checked and the geometry is updated as needed.

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

Remarks


The buffer distance is in the same units as the source shape that is being buffered.

A negative distance can be specified to produce a buffer inside the original polygon. This cannot be used with polyline. ITopologicalOperator methods must be applied on top-level geometries only. Top-Level geometries are point, multipoint, polyline and polygon. To use this method with segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped with a top-level type.

Description

The ConvexHull of a geometry is the minimal bounding polygon such that all outer angles are convex. The ConvexHull of a point is the point itself.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

                           AutomationException
Constructs the geometry that is the set-theoretic intersection of the input geometries. Use different resultDimension values to generate results of different dimensions.

Description

The Intersection of two Geometries of the same Dimension is a Geometry containing only the regions of overlap between the original geometries.

Remarks

Intersection is basically an AND between input geometries.

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon.

constructOffset

public void constructOffset(IPolycurve inCurve,
                            double offset,
                            Object offsetHow,
                            Object bevelRatio)
                     throws IOException,
                            AutomationException
Constructs a curve being the locus of points offset a given distance from another curve. See the enumeration esriConstructOffsetEnum to information on different ways that offset curve can be generated.

Description

ConstructOffset constructs the offset of the given input Polycurve. If the offset parameter is positive, the constructed offset will be on the right side of the curve (left side offsets are constructed with negative offset parameters). Tracing the curve from it's first vertex to the last will give you a direction along the curve. It is to the right and left respective of this direction that the positive and negative parameters will dictate where the offset is constructed. In these terms it is simple to infer where the offset of even horizontal polycurves will be constructed. The offsetHow parameter determines how outer corners between segments are handled. Rounded offset rounds the corner between extended offsets. Bevelled offset squares off the corner after a given ratio distance. Mitered offset attempts to allow extended offsets to naturally intersect, but if that intersection occurs too far from the corner, the corner is eventually bevelled off at a fixed distance.

Remarks

This results produced by this method are sensitive to large offset distances, particularly when the offset distance is larger than the length of the segments in the reference geometry. The remove self intersecting arcs feature is particularly problematic when extremely large offsets are involved.

The sides of the curve are determined from the order of the vertices of the curve. Tracing the curve from the first vertex to the last will give you a direction along the curve it is to the right and left of this direction that the positive and negative parameters will dictate where the offset is constructed. In these terms it is simple to infer where the offset will be constructed.

One alternative is to use buffer to generate the offsets.

                                 AutomationException
Constructs a curve which approximates the input curve by a small number of Bezier segments.

Description

ApproximateByBeziers constructs a curve consisting Bezier segments that being the approximation of input polycurve inCurve. The maxDistance parameter defines the maximum distance between the vertices of the input curve to the generated curve. If maxDistance is zero then for each segment of inCurve there is one Bezier segment created for this geometry. The parameter smoothClosedParts defines whether or not the last segment of the input polyline curve which is closed should be smoothed with the first segment of the curve. The smoothClosedParts parameter is only used if both this geometry and inCurve are polylines. If this geometry or inCurve is a polygon then smoothClosedParts is overwritten and set to true.

The resulting geometry is a polygon or polyline depending on the type of "this geometry" rather than the type of inCurve. If "this geometry" is a polygon and inCurve is a polyline with any open path, an error is returned (result is an empty polygon).
