None, inaccurate or wrong GPS location and elevation

Locus Map processes location and elevation gain from the data it receives from your phone GPS and other location/orientation sensors. If the data is incorrect or contains deviations, the resulting location fix and elevation gain are incorrect. Locus Map, however, offers a few methods for limiting these deviations.

There are a few reasons why the app might not show your location on the map:

• the GPS indicator is white:
  
• tap it and then tap either the skyplot or the button to turn on getting location:
  

• the GPS indicator is orange, there is a badge on the centering button and a warning emerges:
  
• turn on your phone's GNSS:
  

• the GPS indicator is white and tapping the centering button or the GPS skyplot displays a warning:
  
• in system settings, allow Locus Map access to precise location all the time:
  

Open Locus Map settings > GPS&sensors and set the following

• Location filter > select medium or heavier filter
• Google Services assisted location > turn it ON (or OFF, it depends on your device)
• Altitude manager > settings tab > SRTM data - select Optimize GPS values
• Altitude manager > settings tab > Pressure sensor > turn ON (if available)
• Altitude manager > settings tab > Altitude filter - select medium or heavier filter

Sometimes it happens that the GPS chip is malfunctioning or terrain/weather conditions are so demanding that elevation data is incorrect even after applying the measures mentioned above. Then try the following:

• Open Locus Map settings > GPS&sensors > Altitude manager > settings tab > SRTM data - select Replace GPS values - this option calculates elevation gain from offline elevation data without using GPS

Those who are still unsatisfied with the result can change the elevation gain calculation by applying a custom altitude threshold:

• open Expert settings > Customize altitude threshold > enable it
• open a track or route detail > select Edit from the bottom menu
• change altitude threshold with the slider
