摘要
传统的遥感制图需要专业人员借助专业软件对大量分散的局部遥感影像进行复杂的处理,具有很大的局限性。基于Google全球高分辨率遥感影像、Google Maps API V3与KML语言提出一套简易的交互式网上地理数据采集与制图的方案。该方案基于B/S架构,利用Google Maps API侦听器获取地物轮廓特征点的经纬度坐标并按照自定义地理模型渐进地构造地物图形,利用Ajax技术实现前后台数据通信,利用Microsoft XMLDOM方法解决后台数据存储与操作,利用KML图层鼠标事件返回的属性及临时KML图层解决数据选择与操作的可视化。该方案用户界面友好,可用于快速制作大比例尺街区图。
Traditional remote sensing lize specialized software to carefully desired information,have serious 1 m mapping methods,which need professionals to take long time and uticope with a lot of local and isolated remote sensing images to get their itations. This paper presents an interactive geographic data acquisition and mapping solution,which all based on Google＇s global high-resolution remote sensing image and Google Maps API V3. The solution is built into an application of B/S structure. It utilizes the Google Maps API listeners to pick the latitude and longitude coordinates of the special points in landmarks＇ outlines and to progressively construct their graphics with customized geographic models. It also uses Ajax technology to accomplish the data communication between browser and server,and adopts Microsoft XMI.DOM methods to store and process the data in KML files. The visualization of selecting and editing KML data is performed with the help of KML layer mouse event＇s properties and a temporary KML layer. The technology application has a friendly user interface and can be used to produce the large-scale street map quickly.
