在2个晶格和经度点之间以米的距离找到距离



这是我的2分

52.33816422 -106.282889952.33816422 -106.2828634

所有凸台程序都在寻找ddmm.mmmmmmm和dddmm.mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

  rkm = 6371                  # Earth radius in kilometers
  rm = rkm * 1000             # Radius in meters
  dlat_rad = (loc2[0]-loc1[0]) * rad_per_deg  # Delta, converted to rad
  dlon_rad = (loc2[1]-loc1[1]) * rad_per_deg

  lat2_rad, lon2_rad = loc2.map {|i| i * rad_per_deg }
  a = Math.sin(dlat_rad/2)**2 + Math.cos(lat1_rad) * Math.cos(lat2_rad) * Math.sin(dlon_rad/2)**2
  c = 2 * Math::atan2(Math::sqrt(a), Math::sqrt(1-a))
  rm * c # Delta in meters
end
puts distance [52.33816422, -106.2828899],[52.33816422, -106.2828634]
# Will return the answer
