Configuring GPS and Survey Devices

Note: Before connecting your survey devices, ensure that the 1Edit device extension has been installed. For more details, please see the 1Edit Release Notes.

Survey Device settings are accessed from the Settings menu in the Charms bar (see Charms Bar).

Integrate a GPS device

1. Open the Charms Menu and select Settings > Survey Devices.

2. Under GPS Device, toggle GPS Support to On.

   

3. (optional) To track your current GPS position whether or not you are capturing points with your device, toggle Track GPS Position to On.

4. (optional) To automatically centre the map to your current position when using manual or continuous GPS capture, toggle Auto-pan map to follow position to On.

5. In the GPS Port list, select the COM port to which your device is connected.

6. In the Distance Tolerance field, enter a distance in dataset units.

   This is used to define the minimum distance between captured points when doing continuous capture (see Continuous Capture).

7. In the Angle of Deviation Tolerance field, enter an amount (in degrees) to control how far to deviate from a straight line before a new point is captured. This prevents lots of redundant points along a straight line being captured.

   Set this value to 0 if you want to capture all points.

8. In the GPS Quality Levels area, you can configure the ranges of values for coordinate quality levels.

   

   This determines if an amber or red quality level is shown, when either the Accuracy or the Fix drop to the amber or red thresholds.

   • In the Fix drop-down lists, select No fix value, 1-GPS, 2-DGPS, or 3-HPN for both the Amber and Red fields. These values are inclusive, so when the fix drops to the specified level, the warning is displayed.
   • In the Accuracy fields, enter values (in meters) for both Amber and Red.

9. Click the back arrow to close the menu and save your settings.

10. Open the lower app bar and select Devices > GPS.

    The GPS Status panel is displayed.

    

    Refer to any messages in this panel to resolve any issues.

Integrate a Total Station device

1. Open the Charms Menu and select Settings > Survey Devices.

2. Under Total Station Device, toggle Device Support to On.

   

3. In the Total Station Port list, select the COM port to which your device is connected.

4. Click the back arrow to close the menu and save your settings.

5. Open the lower app bar and select Devices > Total Station.

   The Total Station Status panel is displayed.

   

   1Edit checks whether or not Total Station support has been enabled, tests the connection to Total Station, and whether or not the Total Station setup is valid and accepted. Each status check is followed by a tick or cross, and contains information about any potential issues.

6. Click Reset to clear any previously stored settings and calibrations.

7. Click Setup.

   The Instrument Details page is displayed.

8. Enter the height of the Total Station (required) and the default height of the prism (if applicable).

9. Click Stations.

   The Station Selection page is displayed.

10. To indicate the location of the control station (the Total Station), click Pick Control and select a feature such as a point or vertex on the map.

11. To nominate a feature on the map as the reference station, click Pick Reference and then select the feature.

12. To carry out further error checking of the Total Station configuration, click Pick Check and select a point or vertex on the map to represent the check station.

    After you select each station, a construction point is placed at the location indicated, and each point is given a name that can be modified. The height of the selected map feature associated with the station is also displayed.

    If you want to use the height value of the station for calibration, tick the Height box. If a height is not selected, any observations captured from the Total Station will be assigned the current digitising height.

13. Click Calibration.

    This page initially shows the 2D distance from the control station location on the map to the reference and check stations on the map.

14. Target the Total Station at the reference object. Click Observe Reference to take a Total Station observation. Repeat this step for the check station if one has been nominated.

    After each observation the observed 2D distance, the distance is displayed and the difference between the map and observed distances.

    For the reference observation, the horizontal angle of the device is displayed. For the observation check, the observation error is displayed, which is the 2D distance between the location of the check station on the map and the computed location of the check station.

15. Tick Apply differential error to observations to apply the differential error between the map locations and observed locations to observations taken for this Total Station setup.

16. Click Accept to use the calibrated setup for any observations captured.
