I'm a developer currently working on a custom Data Field for Garmin watches, specifically designed for hiking. I'm trying to enhance the navigation experience by displaying key route statistics directly on the watch face.
My main challenge is accessing detailed elevation data from a loaded route. Specifically, I'm looking for a way to retrieve the following information:
The maximum elevation of the entire route.
The remaining total ascent (elevation gain) from the current position to the end.
The remaining total descent (elevation loss) from the current position to the end.
