已知大地经纬度，转化成为WGS84坐标系下的XY坐标？

Question

如题，已知大地经纬度B,L。我想将其转化成为WGS84坐标系的XY坐标，都不考虑高程问题，就想问下，这种情况要不要考虑中央子午线的经度呢？谢谢
那我输入的中央子午线经度是按3度带算还是6度带算呢，我自己试着算了一下，这两种分带的中央子午线经度分别计算的结果不同啊

需要，一、用EXCEL进行高斯投影换算从经纬度BL换算到高斯平面直角坐标XY（高斯投影正算），或从XY换算成BL（高斯投影反算），一般需要专用计算机软件完成，在目前流行的换算软件中，存在一个共同的不足之处，就是灵活性较差，大都需要一个点一个点地进行，不能成批量地完成，给实际工作带来许多不便。笔者发现，用EXCEL可以很直观、方便地完成坐标换算工作，不需要编制任何软件，只需要在EXCEL的相应单元格中输入相应的公式即可。下面以54系为例，介绍具体的计算方法。完成经纬度BL到平面直角坐标XY的换算，在EXCEL中大约需要占用21列，当然读者可以通过简化计算公式或考虑直观性，适当增加或减少所占列数。在EXCEL中，输入公式的起始单元格不同，则反映出来的公式不同，以公式从第2行第1列（A2格）为起始单元格为例，各单元格的公式如下：单元格单元格内容说明A2输入中央子午线，以度.分秒形式输入，如115度30分则输入115.30起算数据L0B2=INT(A2)+(INT(A2*100)-INT(A2)*100)/60+(A2*10000-INT(A2*100)*100)/3600把L0化成度C2以度小数形式输入纬度值，如38°14′20〃则输入38.1420起算数据BD2以度小数形式输入经度值起算数据LE2=INT(C2)+(INT(C2*100)-INT(C2)*100)/60+(C2*10000-INT(C2*100)*100)/3600把B化成度F2=INT(D2)+(INT(D2*100)-INT(D2)*100)/60+(D2*10000-INT(D2*100)*100)/3600把L化成度G2=F2-B2L-L0H2=G2/57.2957795130823化作弧度I2=TAN(RADIANS(E2))Tan(B)J2=COS(RADIANS(E2))COS(B)K2=0.006738525415*J2*J2 L2=I2*I2 M2=1+K2 N2=6399698.9018/SQRT(M2) O2=H2*H2*J2*J2 P2=I2*J2 Q2=P2*P2 R2=(32005.78006+Q2*(133.92133+Q2*0.7031)) S2=6367558.49686*E2/57.29577951308-P2*J2*R2+((((L2-58)*L2+61)*O2/30+(4*K2+5)*M2-L2)*O2/12+1)*N2*I2*O2/2计算结果XT2=((((L2-18)*L2-(58*L2-14)*K2+5)*O2/20+M2-L2)*O2/6+1)*N2*(H2*J2)计算结果Y
