Meridian These are similar to UTM zones. Both apply to large areas based on a line of longitude, both are often left out of field data, and the position is not uniquely defined without them!
子午线与通用横向麦卡托分区相似，同样以一条经线为基础询问大区域，同样通常忽略现场数据，且位置不是绝对的。
Greenwich thus became established as the location of the prime meridian of longitude, and the base line for calculating time zones around the world.
由此格林威治不仅作为起初子午线的所在地，也成为全球计算时区的基准线。
The Greenwich meridian was adopted in 1884 by the International meridian Conference as the line with zero degrees of longitude.
国际本初子午线大会于1884年把横过英国格林尼治天文台的一条经线定为参考线，在该线上经度为零。
This paper mainly introduces how to realize plottings of longitude and latitude grid line, standard map fram and type of graph in the geophysical and geochemical map by WIN-SURFER system.
本文主要介绍了如何在WIN-SURFER环境下实现物化探图件中的经纬网绘制、标准图框绘制、曲线类型图绘制方法。
After the occurrence of flares either the arrangement of magnetic polarity or the neutral line of the longitude field tends to a relatively stable state.
在耀斑爆发后，无论是磁极性排列和纵场中性线都趋于相对稳定状态。
