You can use ArcGIS IPS Setup to collect radio reference data for an indoor positioning system by creating and surveying paths that pass through every area where you want to enable indoor positioning. It is recommended that you survey each area in both directions of the planned survey path to ensure sufficient data collection.
Plan a survey
Survey planning can be completed remotely using ArcGIS Pro before the site visit or onsite using Plan mode in the IPS Setup app.
Before starting the survey, ensure that the survey device's sensors are enabled.
If you planned survey paths in advance, a pop-up appears when you start the survey, with the following options:
- Select existing path—Provides a list of available survey recording paths that can be run immediately without manual sketching and modifications. When you choose this option, a list of survey paths that have been planned for the active floor in the facility appears. Existing survey paths are split into the following categories:
- Planned—Paths that are prepared in advance and facilitate a faster and more efficient survey.
- Surveyed—Paths that were surveyed and can be used if the indoor positioning areas need to be surveyed again. Surveyed paths are visualized with a green buffer around them.
- Create new path—Provides an option to sketch and survey a path if planned paths are not available for an area or floor designated for ArcGIS IPS.
It is crucial to plan sufficient survey recordings to ensure that all defined indoor positioning system (IPS) areas are covered. To create an effective survey path that thoroughly covers a floor plan, place survey points every 30 to 60 feet (10 to 20 meters) and at every point of direction change. Positioning survey points near visible landmarks can help with their identification during the survey.
Tip:
Keep the following in mind when sketching a survey path:
- Sketch the survey path at the location where you want to record. This will help prevent survey paths that go through solid objects such as walls, columns, or furniture.
- Place a survey point on each location along the survey path where the direction changes, such as turning a corner.
- A survey plan must contain at least two points—one to represent the start and one to represent the end of the survey path.
- A survey must be completed continuously without stopping or pausing. Sketch a path that is at least 10 meters (30 feet) long and can be recorded in three minutes or less to reduce the chances of mistakes or interruptions.
- At least one survey point must be placed within a building level, meaning IPS survey recordings should not be sketched and completed outdoors.
To plan a survey using IPS Setup, complete the following steps:
- Open IPS Setup and sign in if necessary.
The map list appears and displays the web maps with an ArcGIS IPS tag that are shared to your ArcGIS organization.
- Tap the name of the web map you want to open.
The web map opens in Map mode.
Note:
In areas with limited internet connectivity, you can load a map while connected and survey a facility without a connection. For example, you can load a map using a stable online connection while outside or while connected to a Wi-Fi network and enter a facility to conduct the survey. In such situations, recordings are cached in the recordings list and automatically uploaded when a connection is established.
- Tap the floor picker and choose the floor to survey.
Note:
To enable the floor picker in a map that contains multiple facilities, zoom to or tap the facility to work on it.
- Tap Survey
.
Note:
If the sensor check bar is red, a pop-up message appears on the screen indicating that the survey cannot be started. Tap the sensor check bar to open the Sensor Check menu and resolve any sensor issues, such as poor compass accuracy or no Bluetooth connection.
If existing surveys are available for the selected map and facility, a pop-up appears with the option to choose an existing path or create a new one.
- Choose Create new path.
- Pan and zoom the map to center the crosshairs over the survey starting point.
- Tap Add Survey Point to add the first survey point.
- Pan the map to center the crosshairs over the next survey point location.
A dotted line appears showing the potential survey path.
- Tap Add Survey Point to add the next survey point.
- Create more survey points as needed.
- Optionally, tap the options button
in the Survey Point pane to edit the survey path.Choose from the following options:
- Reverse path
—Changes the direction of the sketched path by converting the last survey point into the first survey point. - Remove last survey point
—Removes the last survey point that was added. - Discard all survey points
—Removes all survey points. - Save path
—Saves the path to the planned paths section and enables an alternative to the desktop survey planning workflow. - Load path
—Displays the planned paths list and allows existing paths to be loaded, modified, and surveyed. - Undo
—Undoes the previous action.
- Reverse path
- Tap Finish to complete the path.
Once you finish sketching the survey path, you can complete a survey recording for that path.
Complete a survey
Once you add survey points and sketch the path in Plan mode or load an existing path from the planned or surveyed list, you can start performing a survey. The device collects Bluetooth signals from beacons placed in your vicinity. Collected signal strength readings are used to build a radio fingerprint map when using the survey-based method of the Generate Indoor Positioning Dataset tool in ArcGIS Pro. To record a survey, start at the first survey point on the selected path and walk along the planned survey path. Ensure that each survey point is as accurate as possible when you reach its location. Surveys should be at least 10 seconds long, contain at least two survey points, and be limited to approximately three minutes to maintain concentration and avoid interruptions.
When you finish and upload a survey, you are prompted to reverse your path and record from the opposite direction. This can reduce the influence of the shadowing effect caused by the human body on the radio signal. Survey each path in both directions to generate adequate reference data. For example, if you are surveying a corridor that runs north to south, first walk north, then reverse your path and survey south.
When you reverse a path, IPS Setup stays in Survey mode and the path begins at the last survey point. Alternatively, you can edit the path in Plan mode and save sketched survey paths using the options button.
Caution:
Use devices of the same brand and model to record all surveys for a facility. Using devices of different brands can negatively affect the quality of the indoor positioning data and the ArcGIS IPS accuracy.
After sketching a new path or selecting an existing path, complete the following steps to capture the survey recording:
- Position yourself at the first survey recording point.
Tip:
Tap Zoom to Location
to center the map at your location. - Tap Start Recording.
Note:
The IPS Setup app continuously captures radio signals during the survey. Keep your phone oriented in the direction of travel to ensure that the sensor maintains a consistent frame of reference. Follow the planned path as closely as possible, maintaining a steady pace.
- Move at a steady pace to the next survey point and tap Confirm Survey Point upon arrival without stopping or pausing.
Tip:
Follow the planned path as closely as possible. Ensure that the survey points are positioned exactly where they were placed in the Plan mode. For example, if a point was sketched near a wall, move to that location and confirm the point near the wall.
- Confirm each survey point location in sequence until you reach the last one.
Once the last survey point is confirmed, the recording stops and the Upload button appears. The survey recording is completed and can be uploaded to the IPS Recordings feature service.
When you have surveyed every area in the facility where you want to enable ArcGIS IPS, you can use the recordings to create and enable indoor positioning data.
Upload a survey recording
When you confirm the final survey point on a path, the survey automatically ends and the Upload Recording button appears. You can now upload the survey to your ArcGIS organization and use it to create indoor positioning data.
To upload a survey recording, complete the following steps:
- Tap Upload Recording to upload the recording to the IPS Recordings feature service.
Note:
If an internet connection is not available, survey recordings are cached and their status is displayed in the Recordings list. Once a connection is established, the upload process starts automatically.
- Optionally, add comments about the survey recording in the text box in the Upload menu.
Note:
Comments can be used to keep track of survey areas, the direction of survey recordings, and surveyor names, or identify as a reminder for potential mistakes during a recording.
- Tap Upload to upload the survey recording.
The survey recording is added to the IPS Recordings feature service. If there is no connection, the recording is automatically uploaded when a stable connection is available.
Once the survey is uploaded, you have the option to reverse the path.
- Optionally, reverse the path.
If you choose to reverse the path after initially selecting an existing survey path, you can start surveying the reversed path immediately. Alternatively, if you manually created a survey path, the app opens in Plan mode and you can edit the reversed survey path before conducting it.
When you finish surveying a facility, sign in to your ArcGIS organization to review the IPS Recordings feature service and verify that all the survey recordings have been added. If all the recordings were successfully added, you can use the Generate Indoor Positioning Dataset tool to create indoor positioning data.
Once survey recordings are processed, and the indoor positioning data is successfully added to the IPS_Positioning_Datasets, IPS_Positioning_Points feature classes, and the IPS_Positioning_Signals table. Share an Indoor Positioning Data Service and use it to make your map IPS aware. Then, return to the IPS Setup app to test the positioning accuracy.
