工农业生产也需要它,特别是农业更明显,几千年按节气下种,实际上是按日照区的纬度下种。天文地球仪不仅显示节气(季节)同时显示日照角度和每天的光照时间长短。办公与居家都需要知晓日常的天文、时间等信息,它作办公室与居家的陈设品也十分雅致,标致主人的文化素质。特别在住房越来越宽畅的前提下,为它的陈设创造了条件。

用紧密而伸缩性小的细线、细金属丝或纸条,量出地球仪上赤道的周长(单位为毫米),再按公式求地球仪的比例尺(有的地球仪上已标注了标准比例尺,此步可省去)。地球仪的直线比例尺=图上距离/实地距离,即地球仪上赤道周长(mm)/地球赤道实际长(即mm),即可算出地球仪的直线比例尺)。再用上法量出任何两地在地球仪上的图距(mm)除以地球仪的直线比例尺,即可算出两地间的实际水平(其实是球面)距离。也可先量出任何两地在地球仪上的图距(弧长),再利用地球仪上赤道圈的刻度,量算这段距离的弧度,然后将量出的弧度乘以111.1千米(111.1千米是赤道上每度的弧长,是40076千米除以3600所得),就可求得两地间的实际水平距离。
