To collect points with the GNSS rover receiver by determining coordinates of locations on the survey site and storing points at the user's command.
MAGNET Field allows the user to save a point to the job if the current GNSS solution matches the solution type that is set for the current GNSS survey configuration in the Topo Survey Settings dialog. Always check the current GNSS solution in the Status panel at the top of the Topo survey dialogs. To see more details about current GNSS parameters open the Status dialog by clicking in the top left corner and selecting Status in the dialog menu. The GNSS solution requirements for saving points can be changed at any time by clicking
in the dialog title bar and opening the Topo Survey Settings dialog.
The Topo dialog offers various Offset modes to support collection of some inaccessible points by determination of coordinates of accessible locations. See details on offset modes available in the Topo Survey (GNSS). Choose a specific Offset mode in the dialog menu - click and choose the desired mode from the Measure sub-menu.
Use the view selector in the dialog title bar to switch between Normal view and Map view at any time:
Collecting points is possible in both dialog views, Normal view and Map view. Use buttons at the bottom of the dialog to log coordinates and save a point to the job. Brief on-screen text information and tips assist the saving process.
Switch to the Normal view to set up, review and modify collected points data before or during the topo survey.
Note: Next point collected in this survey session will have the code of the previous point if the Codes box was checked in the Persistence tab of the Code Options dialog. The user can manually enter a new code or remove currently used code for the next point at any time.
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 at any time to visually overview the current position and the positions of possible reference objects. Tools available in the Map view:
To avoid cluttering of the elements displayed on the map at the current zoom level, they are combined. Closely positioned points are displayed as a single point with a bracketed number of hidden points next to its name: for example, P001{5}, where 5 is the number of hidden (not displayed) points. If there are more than 99 cluttered points, they will be displayed as {99+}. Hidden elements become visible with the further zoom in.
Note: When measuring lines or areas with points having code of Line or Area type, you may need to extend an existing line or area. As a rule, you have a common code and an individual numeric code string assigned to each of them. To extend a line or area, simply click it - this will instruct MAGNET Field that the selected line or area should be extended with the point you are going to measure next. You can identify your selection: the code and code string in the topo panel at the bottom will be adjusted to the selected object automatically.
The selected line will be extended depending on the side the line is clicked.
The Map view is required to use overlay buttons with quick codes to collect field data and save a point with assigned code or codes by single tap or click.
Quick code buttons with assigned code of Line or Area type feature their own context menu available on right click (long tap). This menu allows the user to quickly add the desired control code to the point. If a numeric code string is assigned to the code on the quick code button, this menu is also useful to quickly increase or decrease the code string number and switch to another line / area in a simple way rather than having to type in the number.
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 Topo dialog:
For more information on the available controls and GNSS receiver statuses, see the Status Panel (GNSS survey) and Topo panel (GNSS survey).
