The following actions are available for Geo Fences:
A geofence is a named three-dimensional geographical area that is composed of four sets of latitude and longitude coordinates as well as parameters for minimum and maximum elevation. Geofences are specific to Divisions, and the RiskBand ARIES Manager only displays geofence locations for devices that are in the same division as the geofence.
After a geofence is defined, whenever a RiskBand device enters the defined area the geofence name will display in the Location field of the Users and Devices content panes. In Figure 8 a geofence has been defined for Panama Beach, Florida, and the device assigned to egray has reported GPS coordinates within that geofence. The device assigned to user.101 is not within the boundaries of any geofence defined for the Div division, so the location for that device is displayed as a dash. The device assigned to eecles could be within boundaries of defined geofences, but because that device is not included in the Div division where the geofence is defined, the location of the device is not displayed.
Figure 8: Geofence display examples
Geofences can be completely enclosed by other geofences. For example, a geofence named “Dartmouth Green” could be completely enclosed by a geofence called “Dartmouth Main Campus.” In these cases, the geofence that has the highest priority (as defined by the lowest “priority number” will be displayed. For example, if “Dartmouth Green” were set has the number 1 priority (by setting the Priority field as 1), and Dartmouth Main Campus were set as the number 2 priority (by setting the Priority field as 2), then devices located on the main campus would be display with a location of “Dartmouth Green” as soon as they entered that geofence. After leaving the “Dartmouth Green” geofence, the devices’ location would display as “Dartmouth Main Campus” until they leave that geofence. Then, if the device is still within a defined geofence, it’s location will be displayed as the geofence name that has the lowest priority number.
Describing Geofence Quadrilaterals
Geofences are described with four sets of GPS coordinates, and the order in which these coordinates are entered determines the shape of the geofence. As a general rule you want enter the coordinates in a continuous clockwise or counterclockwise order. For example, visualize a continuous line being drawn between the sets of coordinates in the order that they were entered, you never want the lines to cross. For example, in the figure below, geofence A describes a convex quadrilateral. Geofence B, on the other hand, describes a concave quadrilateral, and it could be difficult to understand when a location is inside or outside the geofence.
The altitude component of geofence is represented by a minimum altitude and a maximum altitude. This component is most often used in identifying what floor or level a device may be on in a building or structure. However, if your geofences typically just describe terrain, then altitude values can usually be set comfortably above and below the highest and lowest elevation points in the geofenced area.
When creating geofences that describe different levels in structures, the latitude and longitude coordinates stay relatively static, but the minimum and maximum altitude will vary. In the example below, the geofences named Floor 3, Floor 4, and Floor 5, have the same latitude and longitude coordinates, but differing altitude components are used to describe discrete three dimensional spaces.
To create a geofence with the RiskBand ARIES Manager:
1. In the navigation pane, under the Organization section, right-click Geo Fences
and select Create Geo Fence.
2. Choose the Division that the geofence will belong to and click OK.
The Create Geo Fence dialog box appears. This dialog box contains the following fields:
3. Enter values into all the fields of the dialog, and after you are finished click OK.
The geofence is added to the Geo Fences content pane.
You can also create geofences by importing them from a .csv file. This facilitates applying the same geofences to multiple divisions.
The following 12 fields are represented in CSV fileN
• Name
• Priority
• Minimum Altitude
• Maximum Altitude
• Lat1
• Long1
• Lat2
• Long2
• Lat3
• Long3
• Lat4
• Long4
In CSV format, here is an example of entries that will create geofences:
City,1000,-100,1000,30.214000,-85.900000,30.174000,-85.900000,30.174000,-85.800000,30.214000,-85.800000
Bayou,999,-100,1000,30.254000,-85.900000,30.214000,-85.900000,30.214000,-85.800000,30.254000,-85.800000
Bay,998,-100,1000,30.294000,-85.900000,30.254000,-85.900000,30.254000,-85.800000,30.294000,-85.800000

Note: A spreadsheet template is available from RiskBand support that can facilitate the creation of a CSV file for geofences. |
To import geofences from a CSV file:
1. In the navigation pane, under the Organization section, right-click Geo Fences and select Import Geo Fence.
The Import Geo Fence dialog box appears.
2. Click the more icon to the right of the CSV File field and navigate to and select the .csv file you want to import.
3. From the Division drop-down menu, choose the division the geofences will belong to.
4. Click OK.
The .csv file is processed and the geofence created.
To modify a geofence:
1. In the navigation pane, under the Organization section, click Geo Fences.
2. From the Geo Fences content pane, right-click the geofence you want modify and select Modify Geo Fence.
The Modify Geo Fence dialog box appears.
3. Modify the geofence values as required. A description of the geofence fields is provided in Components of Create Geo Fence dialog box.
4. After you have finished modifying the geofence values, click OK.
The Modify Geo Fence dialog box closes.
To view a geofence:
1. In the navigation pane, under the Organization section, click Geo Fences.
2. From the Geo Fences content pane, right-click the geofence you want view and select View Geo Fence.
The View Geo Fence dialog box appears. A description of the geofence fields is provided in Components of Create Geo Fence dialog box.
3. After you have finished viewing the settings, click OK.
The View Geo Fence dialog box closes.
To delete a geofence:
1. In the navigation pane, under Organization, click Geo Fences.
2. From the Geo Fences content pane, right-click the geofence you want to delete and select Delete Geo Fence.
3. Confirm that you want to delete the geofence by clicking OK.
The geofence is deleted.
