The survey page is filled with a map and several controls on and around the map. A screenshot of the survey page is shown below. The projects page also contains the map and has some extra functionalities. 

Map controls

The table below lists the controls that are embedded on or around the map. It is indicated in italic if the functionality is only available on the projects page. Not all controls are directly visible, and the Actions menu in the top bar will give access to a number of the options described in the table below.

Pause the meausurement. Note that the detector will continue collecting data. However, data points are not plotted in the web viewer, and these data points have been marked as 'paused' points.

As a result, data collected when the device was in paused mode can be retrieved from the project.

Centre the map on the last known GPS location

Survey Lines

Enable/disable survey lines that can be used as reference points when doing a survey. The line spacing and angle of the survey lines can be specified in meters or feet, depending on the unit settings.
The survey line settings are stored on the detector and will remain active across reboots of the detector.


If the grid is not visible, try zooming in.
