getMetersPerPixelAtLatitude method

Future<double> getMetersPerPixelAtLatitude(
  1. double arg_latitude,
  2. double arg_zoom
)

Calculate distance spanned by one pixel at the specified latitude and zoom level.

@param latitude The latitude for which to return the value. @param zoom The zoom level.

@return Returns the distance measured in meters.
