| 摘 要： | 随着科技的发展,地图学、测量学、遥感技术、地理信息科学等学科日新月异,出现了各种新概念。特别是椭球体、基准面、地理坐标系、大地坐标系、投影、空间参考等概念中外翻译不一致、容易混淆,常造成概念的指代不明和交叉含糊,给学者之间的交流带来误解。文章通过研究,对这些概念进行了系统解释,澄清了概念之间的继承关系,对比了常用的参数,并说明它们在ArcGIS中的应用。

| Abstract: | With the development of science and technology,cartography,surveying,remote sensing technology,geographic information science change with each passing day.All sorts of new concept appear.At the same time,there are many problems.For example,the Chinese and foreign translation to some concept such as the ellipsoid,datum,geographical coordinate system,the earth coordinate system,projection and the spatial reference are not consistent,easy to confuse,which often cause Ambiguous Reference of Pronouns and cross ambiguity of their concepts.In the paper,we give a detailed explanation of the concept,clarify their inheritance relationship,compare common parameter,and illustrate the application in ArcGIS. |
