经常碰到这两个概念:Geographic coordinate system和projected coordinate sys tem 1、首先理解Geographic coordinate system,Geographic coordinate system直译为 地理坐标系统,是以经纬度为地图的存储单位的。很明显,Geographic coordinate syst em是球面坐标系统。我们要将地球上的数字化信息存放到球面坐标系统上,如何进行操作...
1) projected coordinate system 投影坐标系1. The paper introduces the geodetic coordinate system and the projected coordinate system;it elaborates the transforming ways between the geodetic coordinate system and the projected coordinate system. 为了解决地图制图中不同坐标系之间的相互转换的问题,采用构建...

2000国家大地坐标系也包括地理坐标系(Geographic Coordinate System)和投影坐标系(Projected Coordinate System),无论是地理坐标系还是投影坐标系,都既可以用经纬度表示也可以用距离(一般单位是米或千米)表示。如地理坐标系表示地球上的任意一点位置是与本初子午线(0°经线)以及赤道(0°纬度)的距离,但是,这种表示方法很...
A two-dimensional Cartesian coordinate system that uses x, y, and z coordinates to represent point, line, and area feature locations in two or three dimensions. A projected coordinate system is define
ILinearUnit getCoordinateUnit() The linear unit of a projected coordinate system. void getDomain(double[] xMin, double[] xMax, double[] yMin, double[] yMax) Get the domain extent. int getESRISpatialReferenceSize() The number of bytes required to hold the persistant representation of th...
1、首先理解Geographic coordinate system,Geographic coordinate system直译为地理坐标系统,是以经纬度为地图的存储单位的。很明显,Geographic coordinate system是球面坐标系统。我们要将地球上的数字化信息存放到球面坐标系统上,如何进行操作呢?地球是一个不规则的椭球,如何将数据信息以科学的方法存放到椭球上?这必然要求我...
The following example is the string representation of the California State Plane Zone #1, which is a projected coordinate system. PROJCS["NAD_1983_California_I",GEOGCS["GCS_North_American_1983", DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]], PRIMEM["Greenwich",0...
A projected coordinate system is a flat, two-dimensional representation of the Earth. It is based on a sphere or spheroid geographic coordinate system, but it uses linear units of measure for coordinates, so that calculations of distance and area are easily done in terms of those same units....
