# Method NormalizeCentralMeridian

#### NormalizeCentralMeridian(Geometry)

Folds the geometry into a range of 360 degrees. This may be necessary when wrap around is enabled on the map. If Geometry is an Envelope then a Polygon will be returned unless the Envelope is empty then and Empty Envelope will be returned.

##### Declaration

`public static Geometry NormalizeCentralMeridian(this Geometry geometry)`

##### Parameters

Type | Name | Description |
---|---|---|

Geometry | geometry | The geometry that you want folded. |

##### Returns

Type | Description |
---|---|

Geometry | The folded geometry |

##### Remarks

Supports true curves.

##### Exceptions

Type | Condition |
---|---|

System.ArgumentNullException | geometry or geometry.SpatialReference |

Create, delete, and update features: Add, delete, and update features (geometry and attributes) in a feature layer.

Convex hull: Create a convex hull for a given set of points. The convex hull is a polygon with shortest perimeter that encloses a set of points. As a visual analogy, consider a set of points as nails in a board. The convex hull of the points would be like a rubber band stretched around the outermost nails.

Feature layer selection: Select features in a feature layer.

Nearest vertex: Find the closest vertex and coordinate of a geometry to a point.
