①101.12202 21.774541
②100.168439 21.485952
③101.833532 21.613757
④101.609325 21.176121
答
按3度带投影换算,结果为：
1,X=2409094.984938,Y=409192.596646,
2,X=2377335.054481,Y=621091.743239,
3,X=2391043.170664,Y=482764.109574,
4,X=2342627.856873,Y=459428.950344,那六度带呢？什么时候用三度带什么时候用六度带？大比例尺地图用三度带，小比例尺地图用六度带。按6度带投影换算，结果为：1,X=2410345.225023,Y=719505.687628,2,X=2377335.054481,Y=621091.743239,3,X=2393708.448741,Y=793470.341381,4,X=2344808.445834,Y=771042.887407,
