Indicates the type of shape represented by this geometry.

Namespace: ESRI.ArcGISExplorer.Geometry

Assembly: ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public enum GeometryType

Visual Basic (Declaration)
Public Enumeration GeometryType

Members

	Member name	Description
	Envelope	Indicates the geometry is an Envelope, representing a rectangle with sides parallel to the coordinate system.
	Multipatch	Indicates the geometry is a Multipatch, representing a 3D shape such as a building or a tree.
	Multipoint	Indicates the geometry is a Multipoint, representing an ordered collection of Point objects.
	None	Indicates a non-spatial Table or otherwise unknown type of Geometry which cannot be directly represented by any of the types of Geometry class in ArcGIS Explorer.
	Point	Indicates the geometry is a Point, representing a single location.
	Polygon	Indicates the geometry is a Polygon, representing a shape defined by one or more rings, where a ring is a path that starts and ends at the same point.
	Polyline	Indicates the geometry is a Polyline, representing a shape defined by one or more paths, in which a path is a series of connected linear segments.

Remarks

This enum is returned by a number of properties, and is used to work out which type of shape is represented by the objects:

Geometry.GeometryType - Indicates the underlying class type of the Geometry object.
Column.GeometryType - Indicates the type of geometries stored in the spatial (Geometry) Column of a Table.
Table.GeometryType - Indicates the type of geometries stored in the Table.

Effectively, the Column, FeatureLayer and Table GeometryType properties are all shortcuts to the same information. Each spatial Table can have only one type of Geometry, which may be either Point, Multipoint, Polyline, Polygon or Multipatch. Envelopes cannot be stored as the Geometry in spatial Tables or FeatureLayers.

Non-spatial Tables will return the None GeometryType.

The GeometryType enum is also used in a number of members within the other ArcGIS Explorer namespaces:

GetDefault(GeometryType) - This static method will return a default Symbol for use with the indicated GeometryType.
GeometryTypeToSymbolType(GeometryType) - This static method can be used to identify the appropriate type of SymbolType for drawing the specified GeometryType.

The relationship between SymbolType and GeometryType is constant, but not 1:1; see the SymbolType topic for more information.

Examples

The example below summarizes the number of FeatureLayers in the current Map which have different types of geometry, using the GeometryType property of the FeatureLayer class.

CopyC#

// Get all of the FeatureLayers in the Map.
ESRI.ArcGISExplorer.Mapping.MapDisplay disp = ESRI.ArcGISExplorer.Application.Application.ActiveMapDisplay;
System.Collections.ObjectModel.ReadOnlyCollection<FeatureLayer> flyrs = disp.Map.GetMapItems<FeatureLayer>();

// Count each type of feature layer geometry.
int ptLyrs = 0;
int mptLyrs = 0;
int plineLyrs = 0;
int pgonLyrs = 0;
int mpchLyrs = 0;
foreach (FeatureLayer lyr in flyrs)
{
  switch (lyr.GeometryType)
  {
    case GeometryType.Multipatch:
      mpchLyrs++;
      break;
    case GeometryType.Multipoint:
      mptLyrs++;
      break;
    case GeometryType.Point:
      ptLyrs++;
      break;
    case GeometryType.Polygon:
      pgonLyrs++;
      break;
    case GeometryType.Polyline:
      plineLyrs++;
