Question

英语翻译
Geographic information system (GIS) technology can be used for scientific investigations,resource management,and development planning.For example,a GIS might allow emergency planners to easily calculate emergency response times in the event of a natural disaster,or a GIS might be used to find wetlands that need protection from pollution.
What is a GIS?
A GIS is a computer system capable of capturing,storing,analyzing,and displaying geographically referenced information; that is,data identified according to location.Practitioners also define a GIS as including the procedures,operating personnel,and spatial data that go into the system.
How does a GIS work?
Relating information from different sources
The power of a GIS comes from the ability to relate different information in a spatial context and to reach a conclusion about this relationship.Most of the information we have about our world contains a location reference,placing that information at some point on the globe.When rainfall information is collected,it is important to know where the rainfall is located.This is done by using a location reference system,such as longitude and latitude,and perhaps elevation.Comparing the rainfall information with other information,such as the location of marshes across the landscape,may show that certain marshes receive little rainfall.This fact may indicate that these marshes are likely to dry up,and this inference can help us make the most appropriate decisions about how humans should interact with the marsh.A GIS,therefore,can reveal important new information that leads to better decisionmaking.
Many computer databases that can be directly entered into a GIS are being produced by Federal,State,tribal,and local governments,private companies,academia,and nonprofit organizations.Different kinds of data in map form can be entered into a GIS (figs.1a,1b,1c,1d,1e,1f,and 2).A GIS can also convert existing digital information,which may not yet be in map form,into forms it can recognize and use.For example,digital satellite images can be analyzed to produce a map of digital information about land use and land cover (figs.3 and 4).Likewise,census or hydrologic tabular data can be converted to a maplike form and serve as layers of thematic information in a GIS

Answer 1

技术可能作为科学的调查,资源管理和发展计划的地理数据系统 (GIS).举例来说,GIS 可能允许紧急状况计划者容易地计算假使一个天灾的紧急状况回应时代,或 GIS 可能用来找来自污染的保护洼地.
GIS 是什么?
GIS 是能够捕获的一个计算机系统,储存,分析,而且显示地理地叁考的数据;也就是说,数据依照位置识别.从业者当做包括也定义 GIS 程序,操作人事 ,和进入系统的空间数据.
GIS 如何工作?
关联来自不同的来源数据
GIS 的力量来自能力和空间的上下文的不同数据有关联和有关这关系达成一个结论.我们有的大部份数据有关我们的世界包含位置叁考,在地球上的一些点放置那数据.当降雨数据被收集的时候,它很重要降雨被位于哪里.这被藉由使用一个位置叁考系统,像是经度和纬度做,和也许海拔.横过把降雨数据与其他的数据,像是沼泽的位置作比较风景,可能某沼泽接受小的降雨.这一种事实可能指出这些沼泽可能使,和这一个推论能帮助我们制造最适当的决定有关人应该如何以沼泽互相影响.GIS,因此,能揭露导致较好的 decisionmaking 的重要新数据.
参与 GIS 的可能是直接地的许多计算机数据库正在被生产被联邦的,州,部落的,和地方政府,私人的公司,学术界和非营利的组织.不同的类型数据以地图形式可能被参与 GIS(无花果树.1 一,1 b ,1 c ,1 d ,1 e,1 f,和 2).GIS 也能转换存在数传数据进它能而且使用的表格之内,可能仍然不以地图形式.举例来说,数传人造宇宙站图像可能被分析生产关于土地的数传资讯的地图使用,而且土地包括 (无花果树.3 和 4).同样地,户口普查或 hydrologic 制成表的数据可能被转换到 maplike 形式和服务如 GIS 的数层语干的数据
