Altitude vs. Elevation
- The only Altimeter related functions provided by the Oregon 6x0 are
limited to these data fields:
- All remaining
Elevation Plot page features are directly related to:
- Elevation
- Ambient Pressure
- Barometric Pressure
- See
Altitude vs. Elevation for additional information.
Accuracy
The Oregon 6x0 is designed for recreational navigation purposes and is not intended for activities requiring precise measurements.
When calibrated properly, the Oregon 6x0 can report elevation values between -2,000 and 30,000 feet with +/-50 foot accuracy.
The accuracy of the elevation values displayed and/or recorded can and will be affected by multiple factors:
- Changes in Weather or Air Pressure
- Fluctuations in weather produce the most significant changes in air pressure.
- For example, when a storm is approaching, the sudden drop in air pressure may simulate the effects of moving to a higher elevation.
- Similarly, changes in air pressure occur when moving from indoors to outdoors and vice versa, particularly when moving in and out of climate-controlled buildings.
- Changes in Ambient Air Temperature
- Since barometric altimeters are not temperature-compensated, changes in ambient air temperature can affect altimeter accuracy.
- When significant changes in ambient temperature are experienced, the altimeter must be recalibrated to restore accuracy.
- Calibration Method
- For greatest accuracy, calibration should be performed using a known elevation,
such as a
Benchmark.
- Calibration by GPS alone cannot guarantee accuracy within +/-50 feet.
- A clear view of the sky is essential to obtaining the most accurate
GPS based elevation possible.
Graphing Data
While Garmin may have chosen to label this application 'Elevation Plot' (likely due to being the most frequently used function), it is actually capable of plotting several useful data parameters, and could have just as easily been titled 'Data Plot'. The Elevation Plot application may be used to review the elevation profile of saved tracklogs as well as the currently active tracklog, to calculate the elevation plot of the path ahead to your current destination, or to review ambient and barometric pressure trends to help predict the weather forecast!
