Automatic 

In automatic mode the position coordinates used to create your survey map will be obtained by the available sources in the following order:

  • External (for premium customers)
  • Mobile/Handheld device
  • Locator

RD MAP+ records all position coordinates. These can be exported for post processing

 

External

This premium option works when an external GNSS is available.

You must set up the external GNSS source

 

Mobile device

When this mode is selected the position coordinates are obtained from your handheld device

 

You must share your device position with RD Map+

 

Locator

When this option is selected the map will be created using your locator GNSS coordinates

 

The Locator option will work only if the locator model has a built in GNSS receiver, if this is enabled and if a location fix is available.

 

External GNSS

Position Accuracy reporting mode

You can choose to have a Position Accuracy Indicator on RD Map+ map screen while doing a survey whilst using your mobile devices or Trimble Catalyst DA2 as position source.

This is useful to understand the level of accuracy that you can expect from your surveys.

The widget and icon features will not work if Locator is selected or if you are using a generic third party GNSS receiver.

Available options are:

 

UI Widget and Icon

The UI numeric accuracy widget is shown on the map screen. This provides the numeric value of the horizontal and vertical accuracy obtained.
The numeric values is provided in Metrics only.


The widget and satellite icon are both color coded depending on the  target horizontal and vertical accuracy settings, as follow: 

Green: both targets are met

Orange: only one target is met

Red: both targets are not met
