45×90点

位于美国威斯康辛州里特布罗克的45×90点标志

45×90点是地球上位于两极赤道正中以及本初子午线180度经线正中位置的四个点。

四个点中最知名的是45°0′0″N 90°0′0″W / 45.00000°N 90.00000°W / 45.00000; -90.00000,地处美国威斯康辛州里特布罗克(Rietbrock)。马拉松县公园委员会在此处设立了一座标志。随着个人GPS设备的普及,该标志上的说明进行了修改,以澄清真正的45×90点应位于标志后方约1063英尺(324米)处,而标志建于此处的原因则是由于其靠近公路。

另一个位于陆地上的45×90点是45°0′0″N 90°0′0″E / 45.00000°N 90.00000°E / 45.00000; 90.00000,地处中国新疆靠近蒙古边界的荒凉地区,位于乌鲁木齐东北约240公里。2004年4月13日,一位美国人格雷格·迈克尔斯(Greg Michaels)与一位中国出租车司机Ru Rong Zhao一同从距其110公里的奇台出发到达此地,并在经纬汇合工程中进行了记录。他们的访问表明此处没有任何指示的标志。[1]

另外两个45×90点则是分别位于南太平洋印度洋45°0′0″S 90°0′0″W / 45.00000°S 90.00000°W / -45.00000; -90.0000045°0′0″S 90°0′0″E / 45.00000°S 90.00000°E / -45.00000; 90.00000。有指马航MH370空难发生后的搜救行动曾一度以东南45×90点为轴心进行搜寻。
