@(笔记)[百度地图|高德地图|坐标系转换]
有些公司（比如高德，百度，腾讯）是先经度，再纬度，即Point(lng, lat)。但谷歌坐标的顺序恰好相反，是(lat, lng)。
所以本人提供了一个小工具，提供坐标转换，支持批量导入经度纬度，或者纬度经度
可以尝试左边输入：
116.598121,39.902044;116.598164,39.900781;116.598203,39.899863;116.598042,39.899782;116.597223,39.899918;116.594668,39.900266;116.594567,39.900384;116.594488,39.902108;116.594602,39.902201;116.595013,39.902222;116.597885,39.902249;116.598121,39.902044
然后点击"经纬度 转 纬经度"按钮
结果展现： 39.902044,116.598121;39.900781,116.598164;39.899863,116.598203;39.899782,116.598042;39.899918,116.597223;39.900266,116.594668;39.900384,116.594567;39.902108,116.594488;39.902201,116.594602;39.902222,116.595013;39.902249,116.597885;39.902044,116.598121
