Abstract:

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.
