为推动行业高质量发展,规范测绘市场秩序,测绘地理信息主管部门提出要加强“双随机、一公开”监督检查、测绘行业信用体系建设等方面来强化测绘活动的事中事后监管。本文以测绘项目为抓手,提出了从项目招投标、项目备案、成果汇交、成果应用到“双随机”巡查、信用体系建设的全闭环管理思路,基于WebGIS、数据融合、大数据、工作流等技术,构建了面向省市县三级管理部门的测绘地理信息行业管理与服务平台,阐述了该平台的需求分析、数据组织、技术架构、主要功能和应用情况,并在江苏省等地进行了实地应用,可为国内省级测绘行业管理平台的建设提供参考。 相似文献

Geospatially Enabled Scientific Workflows offer a promising toolset to help researchers in the earth observation domain with many aspects of the scientific process. One such aspect is that of access to distributed earth observation data and computing resources. Earth observation research often utilizes large datasets requiring extensive CPU and memory resources in their processing. These resource intensive processes can be chained; the sequence of processes (and their provenance) makes up a scientific workflow. Despite the exponential growth in capacity of desktop computers, their resources are often insufficient for the scientific workflow processing tasks at hand. By integrating distributed computing capabilities into a geospatially enabled scientific workflow environment, it is possible to provide researchers with a mechanism to overcome the limitations of the desktop computer. Most of the effort on extending scientific workflows with distributed computing capabilities has focused on the web services approach, as exemplified by the OGC's Web Processing Service and by GRID computing. The approach to leveraging distributed computing resources described in this article uses instead remote objects via RPyC and the dynamic properties of the Python programming language. The Vistrails environment has been extended to allow for geospatial processing through the EO4Vistrails package ( http://code.google.com/p/eo4vistrails/ ). In order to allow these geospatial processes to be seamlessly executed on distributed resources such as cloud computing nodes, the Vistrails environment has been extended with both multi‐tasking capabilities and distributed processing capabilities. The multi‐tasking capabilities are required in order to allow Vistrails to run side‐by‐side processes, a capability it does not currently have. The distributed processing capabilities are achieved through the use of remote objects and mobile code through RPyC. 相似文献

蔬菜是人们摄取各种营养成分主要来源之一,由于南极的特殊环境,科考队员所需的各种营养成分很难得到满足。为重视、解决这一问题,文中详细讨论了选用传统东北人冬季食用蔬菜制品,代替南极科考队的越冬食用蔬菜,来满足生理需要。 相似文献
