Wind, elevation & rain radar overlays¶

Wind overlay¶

The wind button in the toolbar shows live, animated wind particles on the map. Their color shows the speed of the gusts. Gusts are stronger than the average wind, so the values can be higher than in a general forecast. The wind shows only from zoom level 10. If you zoom out more, the button becomes pale, and its tooltip tells you why. The wind data comes from Open-Meteo.

	Speed	Beaufort
	0–8 km/h	0–1
	8–15 km/h	1–2
	15–23 km/h	2–3
	23–31 km/h	3–4
	31–39 km/h	4–5
	39–46 km/h	5–6
	46–54 km/h	6–7
	over 54 km/h	7+

A legend at the bottom right shows the same scale on the map. Click its header to open or close it. While the overlay is on, point at the map: a small box at the bottom left then shows the wind direction (where the wind comes from, in degrees) and the gust speed at that point.

On route maps, the wind overlay also changes the color of the route. The color shows the effect of the wind at each point: green for tailwind, yellow for crosswind, red for headwind. Move the mouse pointer on the route to see the headwind or tailwind value in km/h at that point. The legend shows only the speed scale of the particles. The route colors have no legend, because the colors are easy to understand and the pointer gives you the exact value.

Elevation / gradient overlay¶

On route maps, the mountain button in the toolbar colors the route by gradient. Move the mouse pointer on the route to see the gradient at that point. If your GPX file has no elevation data, OnRouteMap tells you that the gradient is not available for this route.

	Gradient
	under -15%
	-15% to -10%
	-10% to -6%
	-6% to -3%
	-3% to -1%
	-1% to 1% (flat)
	1% to 3%
	3% to 6%
	6% to 10%
	10% to 15%
	over 15%

Descents are blue. Climbs go from yellow through orange to red. Thus you see the climbs and descents quickly, without numbers. The Gradient legend at the bottom right opens and closes like the wind legend.

Note

The wind overlay and the gradient overlay both change the color of the route. Thus only one of them can be on. When you turn on one, the other one goes off.

Rain radar overlay¶

The rain cloud button in the toolbar shows an animated rain radar from the DWD (Deutscher Wetterdienst, the national weather service of Germany). It shows approximately the last hour and a forecast for approximately 2 hours. The data comes from Bright Sky. The button shows only if your route or search point is in Germany or near its borders, because the DWD radar covers only this area. The operator can also turn the radar off for all users if the data source has a problem. The same as the wind, the radar shows only from zoom level 10. It covers the visible part of the map, not the full route, so it works the same way for a short ride and for a tour of many days.

A legend at the bottom right shows this scale. It is the same as the official DWD radar legend:

	Intensity
	0.1–0.2 mm/h
	0.2–0.4 mm/h
	0.4–1.0 mm/h
	1.0–2.0 mm/h
	2.0–3.0 mm/h
	3.0–5.0 mm/h
	5.0–7.5 mm/h
	7.5–10 mm/h
	10–15 mm/h
	15–30 mm/h
	30–45 mm/h
	45–75 mm/h
	75–100 mm/h
	100–150 mm/h
	150 mm/h and up

A panel at the bottom of the screen controls the animation. You can start or stop it, go back to "now", or move the slider to see each frame. A label tells you if the frame is in the past, now, or a forecast. Click the arrow on the panel to make it smaller.

Note

If you move the map far away from your route or search point, or out of the covered area, the button tells you why the radar does not show.
