“天地图·河南”连续七年获评五星级省级节点

日前,2020年度地理信息公共服务平台(“天地图”)省级节点综合评估结果公布,河南省地理信息公共服务平台(“天地图·河南”)再次获评“五星级”省级节点。这是自开展综合评估以来,“天地图·河南”连续七年获此殊荣。“十三五”期间,河南省测绘地理信息局着力推动河南省地理信息公共服务平台资源整合,持续开展国家、省、市(县)数据融合更新.     

基于“天地图”的旅游地理信息服务系统设计

"天地图"是国家地理信息公共服务平台,"天地图"旅游是基于"天地图"的旅游地理信息服务平台。"天地图"旅游频道以"天地图"2.0的地理信息数据为基础,聚合国家旅游局的权威旅游信息资源,拥有丰富、全面、权威、可靠、精准的综合旅游信息,并将旅游资源与在线地图服务紧密结合,实现了各类旅游信息的空间定位、分类表达和查询检索,向公众提供专业、特色的基于空间位置的旅游地理信息服务。本文介绍以天地图为基础平台的旅游地理信息服务系统设计,实现国家级、省级、市级旅游信息资源的服务聚合与协同,向用户提供旅游地理信息"一站式"服务。     

空间目标匹配在“天地图·福建”道路数据融合中的应用

数据融合是"天地图·福建"建设的最重要内容之一,每年都会进行1次,其成果是"天地图·福建"电子地图等产品的主要数据源。由于道路数据来源比较多,不同来源的数据之间的变化需要人工提取,导致数据融合耗时费力。本文引入空间目标匹配来提取不同来源道路数据的变化信息,分别使用不同比例尺和相似比例尺的道路数据进行了两次实验,不同比例尺道路匹配精度达93.3%,相似比例尺道路匹配精度达99.4%。空间目标匹配能有效解决属性不一致性问题,提高道路数据融合的效率。     

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.

Relationship of Arctic sea ice and Northern Hemispheric 500 hPa Polar vortices

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated.
