OSM在极地GIS中的应用

随着开源网络地图服务Open Street Map(OSM)数据精度的提高和数据覆盖范围的扩大,其应用已逐渐渗透到各个领域,国内外专家学者对OSM的研究也不断地深入。为探究OSM在极地科考领域的应用实现,同时促进我国极地信息化事业的快速发展,从应用角度出发,论证了OSM在补充谷歌地图实现"雪龙在线"网络信息平台功能的可行性。实现了本地OSM全球地图数据库的建设,并在实现极地网络地图服务(WMS)功能基础之上提出多源空间数据的融合与可视化表达的技术路线,为极地海冰检测与动态变化研究提供了有利的支持,为极地主管部门决策的制定与实施提供了可靠的保障。

Application of OSM in Polar GIS

The application of the open source web mapping service OpenStreetMap(OSM) has gradually penetrated into many fields, following its expansion on data coverage and improvement on data accuracy. Experts and scholars are keepingidgging into the OSM. In order to implement the OSM application in the field of polar expeditons and to promote polar information technology development of China, this article discusses the feasibility of using the OSM as supplement of Google Maps TM when applied on the "XUELONG online" network information platform. A local OSM global database has been created. Meanwhile, a technical route has been put forward on fusion and visual representation of multi-source spatial data, which was based on the realization of WMS ability. This system provides a favorable environment to support dynamic detection of changes in polar sea ice, and it provides a reliable resource for expedition planning and polar devision-making.
