#### Parameters

*geometry1*- The base geometry.
*geometry2*- The comparison geometry.

#### Return Value

True if if geometry1 and geometry2 overlap.

ArcGIS Pro 3.3 API Reference Guide

The base geometry.

The comparison geometry.

Overlaps Method (GeometryEngine)

In This Topic

Returns true if geometry1 and geometry2 overlap.

Syntax

*geometry1*- The base geometry.
*geometry2*- The comparison geometry.

True if if geometry1 and geometry2 overlap.

Exceptions

Exception | Description |
---|---|

System.ArgumentNullException | Either geometry1 or geometry2 or both are null. |

System.NotImplementedException | The method is not implemented for GeometryBag. |

System.InvalidOperationException | Incompatible spatial references between the input geometries. |

Remarks

Two geometries overlap if the dimension of each is equal to the dimension of their intersection, but the intersection itself is not equal to either one.

Example

Determine if geometries overlap

MapPoint pt1 = MapPointBuilderEx.CreateMapPoint(1.5, 1.5); MapPoint pt2 = MapPointBuilderEx.CreateMapPoint(1.25, 1.75); MapPoint pt3 = MapPointBuilderEx.CreateMapPoint(3, 1.5); MapPoint pt4 = MapPointBuilderEx.CreateMapPoint(1.5, 2); // // point and point overlap // bool overlaps = GeometryEngine.Instance.Overlaps(pt1, pt2); // overlaps = false overlaps = GeometryEngine.Instance.Overlaps(pt1, pt1); // overlaps = false // Two geometries overlap if the region of their intersection is of the same dimension as the geometries involved and // is not equivalent to either of the geometries. List<MapPoint> pts = new List<MapPoint>(); pts.Add(pt1); pts.Add(pt2); pts.Add(pt3); List<MapPoint> pts2 = new List<MapPoint>(); pts2.Add(pt2); pts2.Add(pt3); pts2.Add(pt4); // // pt and line overlap // Polyline polyline = PolylineBuilderEx.CreatePolyline(pts); bool isSimple = GeometryEngine.Instance.IsSimpleAsFeature(polyline); // isSimple = true overlaps = GeometryEngine.Instance.Overlaps(polyline, pt1); // overlaps = false // // line and line // Polyline polyline2 = PolylineBuilderEx.CreatePolyline(pts2); isSimple = GeometryEngine.Instance.IsSimpleAsFeature(polyline2); // isSimple = true overlaps = GeometryEngine.Instance.Overlaps(polyline, polyline2); // overlaps = true
