Sensor manager

The Sensor manager was introduced in Cartograph Maps 3.4.0. The sensor manager handles all sensors, including GPS, rotation (compass), and Bluetooth (heart rate, cadence, speed sensor, …).

Settings

• Use altitude from DEM model: If enabled (and altitude data has been downloaded for the current area) then DEM data (e.g. SRT/HGT) is used instead of GPS altitude measurements.
• Keep GPS always on: If enabled then GPS is always kept on when the app is in foreground.
• Show error message when location service fails: If checked then error messages are shown when the GPS receiver cannot be activated.
• Min. distance: The minimum distance between two GPS measurements. If the distance is smaller then the measurement is treated as invalid and ignored.
• Min. interval: The minimum interval between two GPS measurements. If the time of the new measurement is smaller than the interval then the measurement is ignored.
• Min. accuracy: If the GPS signal is less accurate than this value then the measurement is ignored. For instance, if the this value is set to “100 meters” and the current GPS signal accuracy is “200 meters” then the measurement is ignored.
• Min. altitude gain: If the measured altitude gain between two measurements is smaller than this value then the measurement is ignored.
