中国边界测图地理信息网络化保障系统的研究与实现

在各种比例尺地图数据的生产中,凡涉及与周边国家接壤的图幅,都存在国界要素关系处理问题;特别是比例尺大于1∶100万的各种地图的制作生产,国界要素的表示程度较为详细,需以双边签订的议定书为依据,议定书附图作参考,一一对照进行数据制作和成果检校。本文系统结合现实需求,利用目前多比例尺、多投影、多存储格式的边界地理信息数据,结合多源数据融合与基于金字塔模型的瓦片技术,实现了国界数据数字化管理和网络化共享的"一站式"在线服务。

Research and Implementation of Network Support System for China Border Mapping Geoinformation

In the task of mapping the topographic maps with neighboring countries' borders in various scales,there must be border elements to deal with.Particularly when the scale is greater than 1 ∶ 1 000 000,border elements need to be signed in more details according to the bilateral agreement and the protocol map.Based on the realistic needs and the geography information data of multiscale,multi-projection and multi-storage format,the proposed system realized the one-stop services of digital management and network sharing for China boundary topographic data using the multi-source data fusion and the tile pyramid technology.
