Provides access to standard operations on geometric 'value' objects. The input geometries are never modified by these operations. Designed for use in building web services and web applications.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
This interface is new at ArcGIS 9.3.
Members
| Description | ||
|---|---|---|
 |
Buffer | Buffers an array of geometries by each distance specified in an array of distances. The distance units can optionally be specified. Geometries buffered at a given distance can optionally be unioned together. |
|
Densify | Applies the ArcObjects 'Densify' operation to each element of the geometry array. |
|
FindSRByWKID | Defines an SR based upon its well known identifier (WKID) and optionally a WKID for a vertical datum. The resolution and xy tolerances are either computed from the sr horizon or set to defaults. 'authority' is typically either 'EPSG' or 'Esri'. |
|
FindSRByWKT | Defines a spatial reference object based upon its well known text string (WKT) and optionally a WKT for a vertical datum. The resolution and xy tolerances are either computed from the sr horizon or set to defaults. The output sr is always high precision. |
|
FindUnitsByWKID | Defines a unit object based upon its well known identified (WKID). 'authority' is typically either 'EPSG' or 'Esri'. |
|
FindUnitsByWKT | Defines a unit object based upon its well known text string. |
|
GetAreasAndLengths | Calculates areas and perimeter lengths for each polygon in the specified array. |
|
GetLabelPoints | Calculates an interior point for each polygon. |
|
GetLengths | Calculates the length of eacch polyline in the specified array. |
|
Project | Projects an array of geometries from their current spatial reference (pInSR) to a destination spatial reference (pOutSR). The projection process can optionally include a datum transformation if the source and destination SRs have different GCSs. |
|
Relation | Determines the pairs of geometries from the input geometry arrays that participate in the specified spatial relation. |
|
Simplify | Applies the ArcObjects 'Simplify' operation to each element of the geometry array. |
CoClasses that implement IGeometryServer
| CoClasses and Classes | Description |
|---|---|
| GeometryServer (esriGeoDatabase) | Provides access to standard operations on geometric 'value' objects. The input geometries are never modified by these operations. Designed for use in building web services and web applications. |
| GeometryServerImpl | Provides access to standard operations on geometric 'value' objects. The input geometries are never modified by these operations. Designed for use in building web services or other kinds of distributed applications. |
Remarks
The GeometryServer lets clients programmatically apply common geometric operations to arrays of geometry 'value' objects. Buffering, projection of geometries from one spatial reference system to another, and evaluation of spatial relations are some of the operations provided.
For on overview of this interface, please refer to the documentation for the GeometryServer object defined in the geodatabase object library (esriGeodatabase).
