Topo Survey (Optical)

To collect points with the total station by measuring locations on the survey site and storing points at the user's command.

Topo Survey offers different options and methods of point collection. The optical topo survey can be conducted in Sideshot mode, Traverse mode, and various Offset modes.

Set Sideshot, Traverse, or choose a specific Offset mode in the dialog menu - click and choose the desired mode from the Measure sub-menu.

Note: Offset modes are unavailable if the Direct/Reverse measurement method is selected.


Both Sideshot and Traverse modes support measurements using a total station in direct position only and measurement sets when total station is used in both direct and reverse position.

Set up the measurement method in the Survey Settings dialog. This dialog is a part of the Optical configuration wizard. It's possible to change the measurement method in the topo survey by clicking in the dialog's title bar. The dialog title will change according to the selection:

Use the view selector in the dialog title bar to switch between Normal view and Map view at any time:


Taking measurements is possible in both dialog views, Normal view and Map view. More...

Switch to the Normal view to set up, review and modify collected points data before or during the topo survey.


Switch to the Map view at any time to visually overview the occupation position, the positions of possible reference objects, and the current target location. 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.
