Geoid modelDropdownEmbedded EGM96Select the geoid model for height correction (see Height and Geoid Models)
Antenna heightNumber1.30 mAntenna height offset subtracted from all recorded heights

Map Display​

SettingTypeDefaultDescription
Show GPS info line on mapToggleOffDisplay a condensed GPS status line (position, accuracy, satellites) at the top of the map
Show altitude and speedToggleOffDisplay real-time altitude and ground speed on the map

Accuracy Control​

SettingTypeDefaultDescription
Use minimum accuracyToggleOffReject positions that exceed the accuracy threshold
Minimum accuracy unitDropdownMetresUnit for the accuracy threshold (metres or centimetres)
Minimum accuracy allowedSlider150Maximum acceptable accuracy value - positions less accurate than this are rejected
Apply RMS multiplierToggleOffMultiply the RMS accuracy by a custom factor
RMS multiplierNumber1.00Multiplier applied to RMS values (e.g., 1.96 for 95% confidence)

Position Averaging​

SettingTypeDefaultDescription
Position averagingToggleOffCollect multiple samples and average them when placing points
Number of samplesNumber2How many position readings to average

Rangefinder​

SettingTypeDefaultDescription
New point as distance and bearingToggleOffPlace points using rangefinder offset from current position
Use paired rangefinderToggleOffConnect to an external Bluetooth laser rangefinder
Show base points on mapToggleOffDisplay rangefinder base points (where you stood) on the map
Show base point layerToggleOffInclude the base point layer in the layer management screen

Data Collection​

SettingTypeDefaultDescription
Remember last featureToggleOffPre-fill attribute values from the last collected feature
Keep default field valuesToggleOffPreserve default field values between features

Tracking Settings​

Found in Settings > Miscellaneous under the Tracking category.

These settings control GPS track recording behaviour.

SettingTypeDefaultRangeDescription
Show track recording buttonToggleOn-Show/hide the track recording button on the map toolbar
Minimum time between updatesSlider2 seconds0-60 sMinimum time interval between recorded track points
Minimum distance between updatesSlider2 metres0-100 mMinimum distance interval between recorded track points
tip

For vehicle surveys, increase the time interval (5-10 s) and distance (10-50 m) to avoid excessive point density. For walking surveys on foot, the defaults (2 s, 2 m) work well.

Settings Not in the UI​

Some location-related values are managed internally and not directly exposed in the settings screens:

ValueDefaultDescription
Center on GPSOffWhether the map follows the GPS position - toggled via the map toolbar GPS button
Location providerInternal GPSResolved automatically based on which connection toggles are enabled
