简介:一、前言ESRI公司推出了新一代的GIS软件ArcGIS9。其中增加了ArcObjects的产品:面向开发的嵌入式AE(ArcGISEngine)。AE进行开发时彻底地脱离了ArcGIS桌面平台,提高了开发效率和开发的方便程度,从而为用户提供了一个低成本的GIS应用选择。AE提供了COM、.NET和C++的应用程序编程接口(API)。这些编程接口不仅包括了详细的文档,还包括一系列高层次的组件,使得临时的编程人员也能够轻易地创建ArcGIS应用程序。本文对AE进行了介绍,并对其开发和部署进行了初步的探索和研究。
简介:【 摘要 】 目前,城镇公共排水管网建设主体多元化,竣工后的排水管网,无法正常移交到专业单位进行规范化管理。为了解决城镇排水问题,实现水环境质量根本性好转,改善城市生态环境,促进城市生态文明建设,通过先进的技术方法和仪器设备,查清城镇排水管道的健康状况并进行评估,为排水管道养护维修提供重要的基础数据和参考依据。 【 Abstract 】 At present, the main body of urban public drainage network construction is diversified. After completion, the drainage network can not be transferred to professional units for standardized management. In order to solve the problem of urban drainage, realize the fundamental improvement of water environment quality, improve the urban ecological environment and promote the construction of urban ecological civilization, through advanced technology, methods and equipment, the health status of urban drainage pipelines is checked and evaluated, which provides important basic data and reference basis for maintenance of drainage pipelines.
