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...

简介:ArcSWAT报错:数据集未投影;Dataset must have a projected coordinate system 1 报错内容 此报错解决较为简单,报错的内容表明在进行某项操作之前,ArcSWAT要求数据集必须具有投影坐标系统(projected coordinate system),而当前数据集使用的是地理坐标系统(geographic coordinate system)。要解决此问题,你需要为DEM数据...

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
A projected coordinate system (PCS) is a GCS that has been flattened using a map projection. Your data must have a GCS before it knows where it is on earth. Projecting your data is optional, but projecting your map is not. Maps are flat, so your mapmusthave a PCS in order to know...
2) 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...
ARCGIS里的两个坐标系统：地理坐标系统和投影坐标系统。你现在的数据是经纬度的地理坐标系，既然要计算面积那就需要转换为单位为长度的投影坐标系统。同一个文件要么采用地理坐标系，要么采用投影坐标系，不能同时使用。.WGS只是一种世界范围的地理坐标系，同时属于地心坐标系。要计算面积的话就需要转换为...
