GPS Altitude Chart

A GPS Altitude Chart (or elevation profile) is a visual graph that plots an object’s height against time or distance traveled. It is heavily used in aviation, fitness apps like ⁠Ride with GPS, hiking software, and drone mapping to track vertical movement. How the Chart Works

X-Axis: Represents either elapsed time (common in aviation/flight logs) or distance covered (common in hiking/cycling apps).

Y-Axis: Represents altitude (height), usually displayed in feet or meters.

Data Sources: Generated using mathematical triangulation from at least four satellites to measure geometric height. Understanding the WGS84 Base (The Shape Error)

A raw GPS altitude chart can look inherently wrong if not properly calibrated. Naviter.com GPS Altitude vs. Pressure Altitude – Naviter.com
