Auto Topo (GNSS)
To automatically collect points with GNSS rover receiver by auto-saving a point each time a specified criterion is met.
Auto Topo survey is supported in GNSS survey configurations with a GNSS rover receiver and allows you to collect points automatically. While the GNSS rover receiver obtains the required GNSS solution, MAGNET Field checks the status of the criterion in real time and saves the obtained coordinates as another auto topo point in the job at the moment the criterion condition is met.
The required GNSS solution and the criterion that triggers the saving of a point are defined in the Auto Topo Survey dialog. This dialog is a part of the Configuration wizard for GNSS survey. It's possible to review and change the criterion at any time in the auto topo survey by clicking
in the Auto Topo dialog's title bar.
Use the view selector in the dialog title bar to switch between Normal view and Map view at any time:
- Normal view - contains tools to supervise collected point names and codes, displays the current status of auto topo mode and features the auto topo mode start / stop, auto topo points logging pause / continue and instant manual save controls.
- Map view - shows the current position of GNSS rover receiver in real time on the map along with collected points and features the auto topo mode start / stop, auto topo points logging pause / continue and instant manual save controls.
Switch to the Normal view to review and modify collected points data before going to the auto topo mode.
- The Point field displays the name of the first collected point. Enter a point name manually or keep an automatically offered name.
Note: Further points collected in auto topo mode in this survey session will be named automatically according to point naming settings.
- Set a code and attribute information for the point:
- Select an existing Code from the drop-down list. You can manually type a code name. If there is no code with such name, the Code dialog will open when saving. There you can quickly create a new code with entered name.
- If the code type is Line or Area, the respective icon indicates that the point belongs to a line or area. Set a Code String and, if required, select an available Control Code (single or dual) from the drop-down list.
- Click the Code
button to access more code and attribute parameters in the Point Attributes dialog.
Note: Further points collected in auto topo mode in this survey session will have the code of the starting point if the Codes box was checked in the Persistence tab of the Code Options dialog.
- In the Note field, enter a description for the first collected point.
- Enter the antenna height. Click the button to select a method used to measure the antenna height (
Vertical or
Slant). Type the antenna height value manually or click the button to select one of the previously used values from the context menu.
Note: If the Unknown antenna model is selected during configuration, only the Vertical antenna height measurement method is available.
Note: In the mmGPS+ survey and stakeout routines, the antenna height value should be entered as the vertical height from the ground point to the rover's ARP. More...
Switch to the Map view to start the auto topo survey and automatically collect points.
- Click
to start collecting points in auto topo mode. MAGNET Field immediately saves the coordinates obtained from the GNSS rover receiver as an auto topo point, if the specified GNSS solution exists. The next point is automatically saved when the auto topo criterion is met.
- During an auto topo session, click
to pause the logging of auto topo points. To continue paused session click
, MAGNET Field immediately saves another auto topo point and continues to automatically save points according to the criterion.
- Click
to save the currently obtained coordinates as a point immediately, regardless of the criterion status. Such a point is saved as an auto topo point in the job but doesn't affect the current status of the criterion.
- Click
to finish current auto topo session. MAGNET Field stops auto saving points. Between sessions, it is possible to modify point naming, codes, etc., switch to the Normal mode and review and modify data for further points. Click
to start a new auto topo session.
Note: To make auto topo points and their coordinates viewable in the job, open the Points dialog (click
>
>
to open), click
/
in the title bar, select filter by Type from the drop-down menu and check the Auto Topo Points box in the list of point types. To display auto topo points on the Map, check the Auto Topo box in the Points tab of the Map Properties dialog (click
>
>
to open).
For GNSS survey configurations with enabled post processing (the Post Processing box is checked in the Receiver Make dialog), the GNSS raw data file logging controls are available in both, Normal view and Map view of the Auto Topo dialog:
- Click
to start GNSS raw data logging into a file according to the settings in the Rover PP Setup dialog. For the user-defined file name, enter the file name at the logging start. More...
- Click
to stop raw data logging into a file.
For more information on the available controls and GNSS receiver statuses, see the Status Panel (GNSS survey) and Topo panel (GNSS survey).
Click
to change the Auto Topo Survey settings.
Click
to open the dialog menu with additional options. More...
