Oracle Enterprise Asset Management directly integrates with an ESRI GIS System. With this integration, ESRI is the primary source GIS system. The geometry would be part of the ESRI GIS, and EAM holds the reference of the geometry and pulls the geometry whenever required.

This applies both for discrete assets which can refer to Point geometry, and linear assets which can refer to Line geometry of an ESRI Feature Class.

Prerequisites

• Required Software Licenses

  1. ArcGIS for Server

  2. ArcGIS for Desktop

  3. Esri Roads and Highways Extension for Desktop and Server: Applies only for linear assets and if line geometry has measure dimensions. This is needed to publish the line geometry with Linear Referencing capabilities.

• Prerequisite Steps Before Asset Association

  Perform the following steps before associating assets:

  1. Publish the ESRI Feature Class that the discrete or linear asset needs to reference.

  2. Set up the parameters in Map Manager. See Using Map Manager for more details.

   ESRI Geometry:

ESRI maintains the geometry in the Feature Class. Each row has a shape and can be identified by a unique ID.

As part of the ESRI integration implementation, the ESRI Feature Class which has either a point shape or polyline shape should be published to the Server using the ArcGIS for Desktop tool.

If the Feature Class has a polyline shape and a measure dimension, the published webservices must also have linear referencing capability. This option requires ESRI Roads and Highways Extension for Desktop and Server to publish the webservices with linear referencing capability. This would generate additional webservices of geomentrytomeasure and measuretogeometry.

After the required Feature Classes are published, the generated URLs must be seeded in the Map Manager under the linear asset and discrete asset webservices section, based on the polyline or point Feature Class published. Refer to Using Map Manager for more information regarding how the generated URLs should be set up.

   Mapping ESRI Geometry to EAM Linear Assets:

The ESRI Polyline Feature class is mapped to the EAM Linear Asset Segment so that the geometry is associated to the linear asset. If the ESRI integration option is selected, the segment table will include additional columns, ESRI Feature Class and ESRI Feature ID. Use these columns to choose the Feature Class that is set up in Map Manager and enter the unique ID pointing to a row in chosen Feature Class to create the association between the ESRI Polyline Geometry and the EAM linear asset. If geometry has a measure dimension, you can enter the measures and length to specify the portion of measure that the linear segment is mapped.

During the asset visualization in Map Workbench, the geometry is fetched using Webservice Query URLs seeded in the Map Manager by passing the unique ID entered in Linear Asset Segment fields using the Linear Asset Workbench.

The mapping between ESRI Unique ID and the EAM Linear Asset can be performed in several ways. You can select from various mapping options based on the length of geometry and how you wanted to view, manage, or maintain the asset in Enterprise Asset Management. This gives flexibility to define linear assets based on operational needs but not driven by GIS feature objects.

Mapping Options

   Mapping ESRI Geometry to EAM Discrete Assets:

The ESRI Point Feature Class is enabled so that it can be associated to the EAM discrete asset. When the ESRI integration option is selected, the Location tab will display additional fields of ESRI Feature Class and ESRI Feature ID in the Define Asset Number and Define Rebuildable Serial Number forms. Use these fields to choose the Feature Class setup in the Map Manager and enter the unique ID pointing to a row in the selected Feature class to create the association between the ESRI Point Geometry and the EAM discrete asset.

During the asset visualization in the Map Workbench, the geometry is fetched by passing the unique ID using Webservice Query URLs seeded in the Map Manager.
