The 'degree' column gives the map width in degrees, for map at that zoom level which is 256 pixels wide. Die Werte für "m / Pixel" sind berechnet mit einem Erdradius von 6372.7982 km. "Scale" (map scale) is only an approximate size comparison and refers to distances on the equator. In addition, the map scale will be dependent on the monitor. These values are for a monitor with a 0.3 mm / pixel (about 85.2 American DPI)
Berechnung für Meter pro Pixel
The distance represented by one pixel (S) is given by
- S=C*cos(y)/2^(z+8)
- C: Umfang der Erde am Äquator
- z: Zoom-Level
- y: Breite des interessierenden Ortes
Make sure your calculator is in degrees mode, unless you want to express latitude in radians for some reason. C should be expressed in whatever scale unit you're interested in (Seemeilen, Meilen, Meter, Fuss, smoots, etc). Since the earth is actually ellipsoidal, there will be a slight error in this calculation. But it's very slight. (0.3% maximaler Fehler)
