BDS与GIS融合数据采集技术应用研究

Application research on data fusion acquisition technology of BDS and GIS

针对地理信息综合数据采集与应用需求,基于北斗导航系统和开源MapWinGIS技术,研制了基于北斗导航系统的数据采集应用平台,解决了多源技术融合数据采集、坐标系自适应转换与快速匹配等关键技术问题。经过不同方案应用测试,结果表明,平台定位与底图匹配精度高,能够满足一般性的综合地理信息数据采集与底图调绘需求,可广泛应用于地理国情普查与监测、野外数码调绘及其他行业外业数据采集应用。

Aiming at data collection and application of geographic information, based on the BDS navigation system and MapWinGIS technology, this paper developed the Geographic Information Acquisition Platform Based on BDS for integrated. The key problems such as synchronous acquisition of multi-source data, adaptive transformation of coordinate system and fast matching are solved. Different schemes test indicated that the platform had the high precision for positioning and mapping, and can meet the general geographic information data collection and map annotation needs. And also can be widely used in geographic conditions monitoring, field digital mapping and outside data collection services and other industries.
