Compute Positioning Quality (Indoor Positioning)

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

Summary

Populates an IPS Quality dataset generated by the Create IPS Quality Dataset tool.

This tool extracts the positions computed by the IPS engine from IPS Quality recordings collected using the ArcGIS IPS Setup app and associates them with reference positions along the recording trajectory. Reference positions are obtained through a temporal interpolation of the waypoints (called survey points in the IPS Setup app) of a recording trajectory.

Usage

• The output point features will be appended to the Computed Positions and Reference Positions feature classes in the specified Target IPS Quality Dataset parameter value.

• This tool creates the following fields:

  • Level Match
  • LOS to Computed
  • Distance to Computed
  • Level of Accuracy

  See Compute IPS positioning quality for more information.

• The Target IPS Quality Dataset parameter value must be a feature dataset in a file or enterprise geodatabase containing two feature classes that conform to the Computed Positions feature class and Reference Positions feature class in the IPS model.

• The IPS Recordings Features parameter value must be a feature layer, feature class, or feature service that conforms to the IPS Recordings feature class in the IPS model.

• The Sight Blocking Details Features parameter value must be a feature layer, feature class, or feature service that conforms to the Details feature class in the Indoors Information Model. Filter these features to include only those that are blocking the line of sight. For example, use a definition query to only select features representing walls. Typically, this information is encoded in the Use Type field.

Code sample

ComputePositioningQuality example 1 (Python window)

The following Python window script demonstrates how to use the ComputePositioningQuality function to populate an IPS Quality dataset.

# Name: ComputePositioningQuality_example1.py 
# Description: Populates an ArcGIS IPS Quality dataset 
 
# Import system modules 
import arcpy 
 
# Set local variables 
 quality_dataset  = r"C:\\demo.gdb\\IPS_Quality" 
 quality_recordings = r"C:\\demo.gdb\\IPS_Recordings" 
 details_lyr = r"C:\\demo.gdb\\Details"  
 
# call the Compute Positioning Quality tool to populate the quality dataset
arcpy.indoorpositioning.ComputePositioningQuality(quality_dataset, quality_recordings, details_lyr)
