Interpret positioning performance

Available for an ArcGIS organization licensed with the IPS extension.

ArcGIS IPS allows you to visualize and interpret positioning quality data using basic and advanced visualizations.

Note:

If you detect locations in your environment where ArcGIS IPS performance is poor, review the ArcGIS IPS deployment guidelines to configure ArcGIS IPS for optimal performance.

Basic visualizations

The following sections describe basic visualizations that you can apply to the ArcGIS IPS quality dataset to gain insights about the positioning quality of your deployment.

Identify the accuracy levels

The Accuracy Level field of the Reference Positions feature class represents a classification of the positioning performance based on the distance between your actual location and the location computed by the ArcGIS IPS engine.

Symbolizing the reference position features on a map allows you to visualize and identify areas where ArcGIS IPS performs at different levels of accuracy. Complete the following steps to identify the accuracy levels:

  1. Add the Reference Positions feature class to a map.
  2. Configure the map as floor aware.
  3. Configure the Reference Positions layer as floor aware.
  4. Choose the Reference Positions layer in the Contents pane.
  5. On the Feature Layer tab, in the Drawing group, click the arrow below Symbology Symbology and choose Unique Values Unique Values.

    The Symbology pane appears, allowing you to further customize the way the layer is classified and symbolized.

  6. Click the Field 1 drop-down arrow and choose Accuracy Level.

    The color of the reference position features are based on the Accuracy Level field, allowing you to visualize areas with different levels of accuracy.

  7. Optionally, choose a color scheme from the Color scheme drop-down list in the Symbology pane or manually edit the symbol of each class on the Classes tab.
  8. Optionally, create a filter on the layer to view a subset of reference position features on the map.

    This can be helpful for clear visualization if there are many Reference Positions features that overlap or are located close to one another.

    You can do the following to filter the layer:

Match location level

The Level Match field of the Reference Positions feature class reports if your actual location and the location computed by the ArcGIS IPS engine are at the same level.

Symbolizing the reference position features on a map allows you to visualize and identify the areas where ArcGIS IPS locates you on the wrong floor. Complete the following steps to match location levels:

  1. Add the Reference Positions feature class to a map.
  2. Configure the map as floor aware.
  3. Configure the Reference Positions layer as floor aware.
  4. Choose the Reference Positions layer in the Contents pane.

    You can do the following to filter the layer:

Set the location source

The Location Source field of the Reference Positions feature class indicates the technology used by the ArcGIS IPS engine to compute your position. The supported location sources are Bluetooth, Wi-Fi, Apple indoor positioning, or Global Navigation Satellite System (GLONASS).

Note:

The location source may differ from the type of positioning supported by an indoor positioning file. This is because the ArcGIS IPS engine also uses other available sources to compute the best possible indoor location.

Symbolizing the reference position features allows you to visualize which location technology is used in different areas of your environment and perform appropriate steps to correct unexpected behaviors. For example, if you have a Bluetooth-based deployment, and the areas use GLONASS instead, review your beacon deployment and ensure that you define proper entrance and exit transitions.

Complete the following steps to visualize location sources:

  1. Add the Reference Positions feature class to a map.
  2. Configure the map as floor aware.
  3. Configure the Reference Positions layer as floor aware.
  4. Choose the Reference Positions layer in the Contents pane.
  5. On the Feature Layer tab, in the Drawing group, click the arrow below Symbology Symbology and choose Unique Values Unique Values.

Use spatiotemporal analysis

The IPS Time field in the Reference Positions and Computed Positions feature classes indicates the time when a position was computed by the ArcGIS IPS engine. This field together with the Recording GUID field creates a unique correspondence between the reference position features and the computed position features.

Combine the analysis

You can visualize data by combining multiple fields of the Referenced Positions feature class. A multifield visualization allows you to identify trends based on field correlation that may have contributed to suboptimal ArcGIS IPS performance.

Symbolizing the reference position features on a map by combining the Level Match, LOS to Computed, and Accuracy Level field values gives you a general overview of the quality of your deployment.

Complete the following steps to visualize ArcGIS IPS performance by combining analysis fields:

  1. Add the Reference Positions feature class to a map.
