摘要(Abstract):
针对目前主流的网络地图与大多数的GIS桌面系统所支持的OGC的WFS、WMS、WCS等空间数据服务发布规范不兼容导致无法直接被GIS桌面系统集成的问题,该文提出了一种基于Web嵌入的网络地图集成模式,将网络地图作为参考图层集成至GIS桌面系统,通过矢量数据采集工具的开发,将基于网络地图采集的地理信息数据添加至GIS桌面系统的矢量数据图层中,并对网络地图与GIS系统的交互方法进行了研究。由于大多数网络地图都进行了位置加密处理,该文通过位置纠偏方法对位置偏差进行纠正,提高了矢量数据采集的位置精度。最后,该文实现基于网络地图的矢量数据采集工具的开发,并使用该工具对山南地区乃东县的居民地数据进行了采集,验证了该文提出的观点和方法。
