摘要
地理信息在我国土地资源中的地位十分重要,随着地理信息系统的应用越来越广泛,地理信息的及时更新也越来越重要,测绘是建立地理信息系统的基础工作,以测绘地理信息系统为核心的信息链已经基本形成并得到了广泛的应用。随着各种应用对地理信息的精确度的要求越来越高,传统测绘方法已经不能满足地理信息产业链的需求。本文简要介绍了地理信息系统、地理测绘系统和及其应用,并指出了地理测绘信息系统的设计重点。
The status of geographic information in China's land resources is very important. As the application of geographic information system becomes more and more widespread, it is more and more important to update the geographical information in time.Surveying and mapping is the basic work to establish geographic information system. The information chain whose core is surveying and mapping geographic information system has been basically formed and widely used. With the increasing demands of various applications for the accuracy of geographic information, the traditional surveying and mapping methods have been unable to meet the needs of the geographic information industry chain. This article briefly introduces the GIS and geographic mapping system and their applications, and points out the design priorities of surveying and mapping geographic information system.
