  “城市绿地覆盖”译为未确定词的双语例句
     To plan and manage greenland reasonably, we employ remote sensing to obtain the information for the covergage of greenland, and then build and manage the greenland database in the GIS environment. Using the new district of Urumqi as a case study, this work utilized the ActiveX control object“MapObjects”(which provides the capabilities of drawing and space analysis) and the VB programming environment, and developed a software system for classification and management of greenland information, based on geenspace’s characteristics.
     为了合理地对城市绿地进行规划管理,运用遥感手段获取城市绿地覆盖信息,进而在GIS环境中建库和管理绿地数据,本研究以乌鲁木齐新市区作为试点对象,结合提供制图与空间分析功能的ActiveX控件MapObjects,以及VB的程序设计环境,针对城市绿地特有属性开发了一套用于城市绿地分类及信息管理的软件系统。

     As the main data sources for urban vegetation high resolution imagery provides a good basis for recognizing and monitoring small scale structure changes. Going far beyond the methodical limits of pixel based and manual interpretation approaches,multi resolution image segmentation and object oriented image analysis approaches are used for extracting information from airborne remote sensing data. This paper presents a snapshot of work to detect vegetation information in Daqing city using this new patented technique.
     高分辨率遥感影像是城市绿地信息快速提取的主要数据源 ,文中以多尺度影像分割与面向对象影像分析方法为主要技术 ,利用样本多边形对象的成员函数建立训练区 ,自动提取大庆市城市绿地覆盖信息 ,达到清查城市绿地的目的。

Monitoring urban vegetation is one of the major environmental applications in remote sensing today.As the main data sources for urban vegetation high resolution imagery provides a good basis for recognizing and monitoring small scale structure changes. Going far beyond the methodical limits of pixel based and manual interpretation approaches,multi resolution image segmentation and object oriented image analysis approaches are used for extracting information from airborne remote sensing data.This paper presents a snapshot of work to detect vegetation information in Daqing city using this new patented technique. It allows the segmentation of an image into highly homogeneous image objects in any chosen resolution and the generation of a network of image objects. The process does not classify single pixel but rather image object.Not only spectral information but also spatial, physical and contextual characteristics of image objects are used for classification.Classification is conducted by fuzzy logic,and image objects are evaluated using membership function classifiers.Membership functions are used to produce class description, which consists of a set of fuzzy expressions from appropriate sample objects.The result of vegetation information extraction is promising and the precision of classification is higher than other conventional processes.It is obvious that this new image analysis approach offers a satisfying solution to extract information quickly and efficiently.
