GPS经纬度的表示方法及换算
想要认识GPS中的经纬度,就必须先了解GPS,知道经纬度的来源:1. GPS系统组成GPS是Gloabal Positioning System 的简称,意为全球定位系统,主要由地面的控制站、天上飞的卫星、咱们手里拿的接收机三大块组成,我们所使用的GPS包括手持机和车载导航机本质上都是GPS接受机。
2. GPS接收机接收机大大小小,千姿百态,有袖珍式、背负式、车载、船载、机载什么的。
一般常见的手持机接收L1信号,还有双频的接收机,做精密定位用的。
3. 坐标系地形图坐标系:我国的地形图采用高斯-克吕格平面直角坐标系。
在该坐标系中,横轴:赤道,用Y表示;纵轴:中央经线,用X表示;坐标原点:中央经线与赤道的交点,用O表示。
赤道以南为负,以北为正;中央经线以东为正,以西为负。
我国位于北半球,故纵坐标均为正值,但为避免中央经度线以西为负值的情况,将坐标纵轴西移500公里。
北京54坐标系:1954年我国在北京设立了大地坐标原点,采用克拉索夫斯基椭球体,依此计算出来的各大地控制点的坐标,称为北京54坐标系。
GS84坐标系:即世界通用的经纬度坐标系。
6度带、3度带、中央经线。
我国采用6度分带和3度分带:1∶2.5万及1∶5万的地形图采用6度分带投影,即经差为6度,从零度子午线开始,自西向东每个经差6度为一投影带,全球共分60个带,用1,2,3,4,5,……表示。
1∶1万的地形图采用3度分带,从东经1.5度的经线开始,每隔3度为一带,用1,2,3,……表示,全球共划分120个投影带4. 经纬度的来源为了精确地表明各地在地球上的位置,人们给地球表面假设了一个坐标系,这就是经纬度线。
那么,最初的经纬度线是怎么产生又是如何测定的呢公元344年,亚历山大渡海南侵,继而东征,随军地理学家尼尔库斯沿途搜索资料,准备绘一幅“世界地图”。
他发现沿着亚历山大东征的路线,由西向东,无论季节变换与日照长短都很相仿。
于是做出了一个重要贡献——第一次在地球上划出了一条纬线,这条线从直布罗陀海峡起,沿着托鲁斯和喜马拉雅山脉一直到太平洋。

3. 坐标系 地形图坐标系:我国的地形图采⽤⾼斯-克吕格平⾯直⾓坐标系。
在该坐标系中,横轴:⾚道,⽤Y表⽰;纵轴:中央经线,⽤X表⽰;坐标原点:中央经线与⾚道的交点,⽤O表⽰。
⾚道以南为负,以北为正;中央经线以东为正,以西为负。

坐标计算距离公式表格
坐标计算距离公式表格在地理和数学中,计算两个坐标之间的距离是一个常见的需求。
无论是导航系统、地图应用还是其他位置相关的应用,计算坐标之间的距离都是必不可少的。
本文将介绍三种常用的计算坐标距离的公式,并提供表格形式的示例。
1. 直线距离直线距离是最简单也是最直观的坐标之间的距离计算方法。
这个方法基于勾股定理,通过计算两点间的直线距离得出结果。
直线距离的计算公式如下:d = sqrt((x2 - x1)^2 + (y2 - y1)^2)其中,(x1, y1)和(x2, y2)表示两个坐标点的横纵坐标,d表示两点之间的直线距离。
以下是一个示例表格,展示了直线距离计算的结果:起点终点直线距离(0,0) (3,4) 5(-1,2) (4,6) 7.211(2,3) (2,3) 02. 曼哈顿距离曼哈顿距离是以曼哈顿街道的特点命名的一种距离计算方法。
它通过计算两点之间沿着网格线移动的总距离来得到结果。
曼哈顿距离的计算公式如下:d = |x2 - x1| + |y2 - y1|其中,(x1, y1)和(x2, y2)表示两个坐标点的横纵坐标,d表示两点之间的曼哈顿距离。
以下是一个示例表格,展示了曼哈顿距离计算的结果:起点终点曼哈顿距离(0,0) (3,4) 7(-1,2) (4,6) 13(2,3) (2,3) 03. 切比雪夫距离切比雪夫距离是一种以国际象棋中国王的走法计算距离的方法。
它表示两点之间在最短步数下移动的距离。
切比雪夫距离的计算公式如下:d = max(|x2 - x1|, |y2 - y1|)其中,(x1, y1)和(x2, y2)表示两个坐标点的横纵坐标,d表示两点之间的切比雪夫距离。
以下是一个示例表格,展示了切比雪夫距离计算的结果:起点终点切比雪夫距离(0,0) (3,4) 4(-1,2) (4,6) 7(2,3) (2,3) 0通过本文,你了解了三种常用的计算坐标距离的公式:直线距离、曼哈顿距离和切比雪夫距离。
GPS经纬度的表示方法及换算
想要认识GP S中的经纬度,就必须先了解GPS,知道经纬度的来源:1. GPS系统组成GPS是 Gloaba l Positi oning System的简称,意为全球定位系统,主要由地面的控制站、天上飞的卫星、咱们手里拿的接收机三大块组成,我们所使用的GPS包括手持机和车载导航机本质上都是G PS接受机。
2. GPS接收机接收机大大小小,千姿百态,有袖珍式、背负式、车载、船载、机载什么的。
一般常见的手持机接收L1信号,还有双频的接收机,做精密定位用的。
3. 坐标系地形图坐标系:我国的地形图采用高斯-克吕格平面直角坐标系。
在该坐标系中,横轴:赤道,用Y表示;纵轴:中央经线,用X表示;坐标原点:中央经线与赤道的交点,用O表示。
赤道以南为负,以北为正;中央经线以东为正,以西为负。
我国位于北半球,故纵坐标均为正值,但为避免中央经度线以西为负值的情况,将坐标纵轴西移500公里。
北京54坐标系:1954年我国在北京设立了大地坐标原点,采用克拉索夫斯基椭球体,依此计算出来的各大地控制点的坐标,称为北京54坐标系。
GS84坐标系:即世界通用的经纬度坐标系。
6度带、3度带、中央经线。
我国采用6度分带和3度分带:1∶2.5万及1∶5万的地形图采用6度分带投影,即经差为6度,从零度子午线开始,自西向东每个经差6度为一投影带,全球共分60个带,用1,2,3,4,5,……表示。
1∶1万的地形图采用3度分带,从东经1.5度的经线开始,每隔3度为一带,用1,2,3,……表示,全球共划分120个投影带4. 经纬度的来源为了精确地表明各地在地球上的位置,人们给地球表面假设了一个坐标系,这就是经纬度线。
那么,最初的经纬度线是怎么产生又是如何测定的呢公元344年,亚历山大渡海南侵,继而东征,随军地理学家尼尔库斯沿途搜索资料,准备绘一幅“世界地图”。

他发现沿着亚历山大东征的路线,由西向东,无论季节变换与日照长短都很相仿。
于是做出了一个重要贡献——第一次在地球上划出了一条纬线,这条线从直布罗陀海峡起,沿着托鲁斯和喜马拉雅山脉一直到太平洋。
