Topo

The Topo dialog enables you to conduct a stationary survey and can be opened in two views: Normal and Map. Click the Topo dialog's title bar to switch between Normal and Map modes.

Note: In specific RTK and DGPS configurations, when starting the base, you can receive the following warning:

"Your rover firmware does not recognize the base antenna. Make sure that height of measured points is correct".

Refer to this section to solve the issue.


Topo Normal View

The dialog contains the Status panel at the top.

To perform measurements:

  1. Enter the name of the Point to be logged. For a new job, default numbering for a topo point starts with 100. Exact naming depends on the parameters selected on the Name tab of the Point Attributes dialog or Config: Point Naming dialog, specifically:

  2. Enter code and attribute information for the point.
  3. Enter the Antenna Height and set the type of height measurement (Vertical or Slant).

    Note: If the Unknown antenna model is selected during configuration, Topo and Stake dialogs allow only Vertical antenna height measurement method.

    A note regarding mmGPS+ survey and stakeout routines: in the Ant Height field, the antenna height value should be entered as the vertical height from the ground point to the rover's ARP. See below:

  4. The current coordinates values display in the coordinate system assigned in Configure Display dialog.
  5. Click to open a file for data logging in surveys with post processing. This button is shown if you have selected the Post Processing check box in the Receiver Make dialog. For the user-defined file name, enter the file name at the logging start. Click to stop data logging into a file.
  6. Start the measurement operation according to your preference:

Topo Map View

The dialog shows the stored points graphically and presents the information similar to the Normal View so all the survey process can be done from here as well.

The Map View contains three main instruments:

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.

The Map pane has six data fields in its bottom part, three on the left and three on the right side. Click on any data field to open Select Value to display dialog for that field. Select the desired parameter from the list and click to display its value during the survey. You can change the parameter to display by clicking on it at any time.

A note regarding mmGPS+ survey and stakeout routines: in the Ant Height field, the antenna height value should be entered as the vertical height from the ground point to the rover's ARP. See below:

Context menu

The dialog's context menu is displayed on a right-click in empty space of the map. The menu contains the following items:


Note: When measuring points for multiple lines or areas, you may need to extend an existing line or area. As a rule, you have codes and strings assigned to each of them. To extend a line or area, simply click it - this will instruct MAGNET Field that selected line (area) should be extended with the point you are going to measure next. You can identify your selection: the code in the bottom part of the dialog will be selected automatically.

The line will be extended depending on the side the line is clicked.


If you are using Quick Codes buttons, you can press and hold on the necessary Quick Code. In the context menu that appears, there are the +/- items.

If the quick code/string value is a number, the code/string number will increment/decrement, respectively. This allows to increase or decrease the code/string number in a simple way rather than having to type in the number.


Select Value to Display

Select the required item from the list and click to display its value during the survey.
