ArcGIS IPS Information Model

Available for an ArcGIS organization licensed with the ArcGIS IPS extension.

The ArcGIS IPS Information Model supports the management of indoor positioning information required to share properly configured web maps and mobile map packages for use with the ArcGIS IPS Setup app and other ArcGIS IPS-enabled apps. Additionally, it contains the data structures required to assess indoor positioning performance.

The information model consists of two parts:

• The ArcGIS IPS Data Model—Includes the tables and feature classes required to enable indoor positioning and maintain up-to-date information about the beacon infrastructure.
• The IPS_Quality dataset—Contains point feature classes that are used to assess the performance of an ArcGIS IPS deployment.

The information model can also use the following data from the ArcGIS Indoors Information Model:

• Floor plan data—Includes the Sites, Facilities, Levels, Units, and Details feature classes that contain floor plan and indoor spaces data.
• Transitions—In the Indoors model, the Transitions feature class contains features that represent transitions between floors, such as stairs and elevators. The ArcGIS IPS model extends this feature class by using a domain to include transitions between indoor and outdoor spaces.
• Pathways—Linear features that represent traversable space. When marked for use with the ArcGIS IPS app, path snapping is enabled to enhance positioning accuracy.

IPS Data Model

You can use the Create IPS Data Model tool to create the ArcGIS IPS Data Model in an existing Indoors workspace. The data model includes the following components, which are required to set up and enable the indoor positioning system:

• Feature classes:
  • IPS_Recordings
  • IPS_Beacons
  • IPS_Positioning_Datasets
  • IPS_Positioning_Points
• IPS_Positioning_Signals table

The IPS_Recordings feature class is used to plan and store survey recordings and quality recordings of an indoor environment. Sensor data and its metadata are stored as an attachment on this layer.

The Compute Positioning Quality tool transforms quality recordings into reference positions and computed positions features, which encode information about the performance of a deployment. Reference positions denote points for which a quality assessment is available, while computed positions represent the indoor positions generated by the ArcGIS IPS engine for each of these references.
