Research On Sharing Mechanism Of Lunar Data Base On Spatial Information Service Cloud

The moon is the nearest planet of earth.Human has been filled with longing andyearning to hope to know the friend. The beginning of the study from humanobservation has been a few hundred years, the human use a variety of techniques toprobe the moon.Through hundreds of years of perseverance and efforts, human lunardata and information, especially in recent years, human use of remote sensingtechnology, digital mapping technology and other high-tech comprehensive detectiontechnology on the moon, lunar mass probe data and information for humanunderstanding of the moon, and the understanding of the moon, to further explore themoon has accumulated a great deal of valuable asset. Lunar exploration data andresults of human understanding, the basis of the understanding of the moon, is thebasis to further explore the moon, and national organizations and scholars to study inorder to obtain more information and resources wealth of lunar data.Lunar data organized by individual countries to detect their own research, themoon data from the beginning to the multi-source, heterogeneous, multi-scalecharacteristics of China’s own lunar probe satellite ‘Chang’e ‘satellite also has its owncharacteristics, which is to study by those who want a different Moon Data Mooninconvenience. And terrestrial applications in the Chang-e works, the Chinese lunardata storage, while the moon scientists scattered throughout the country, and howscientists have convenient access to the lunar data to study the moon AppliedResearch. Establish a unified lunar data format, unified management and publishingdata of the mass of the moon, to enable people to share a valuable asset of mankind,academics and researchers have a lot of research.The rise of cloud technology, data storage and management hate to progress, application and development of cloud computing to the G/S mode is given a newconcept, the S-side development for spatial information service cloud to cloudcomputing and cloud storage, data transmission standards for spatial information andmetadata management infrastructure to HGML industry identifies XXML applicationindustry vast amounts of data classification and organization of metadata for furtherrefinement in order to improve data search the efficiency of data sharing. As the datastorage space information service cloud dispersed, the use of dynamic redundancy andload balancing technology to ensure data integrity and disaster recovery, thus ensuringto provide users with transparent data services.In this paper, the characteristics of existing lunar data, structure, format, and thecurrent geographic information sharing way, shared technology, shared standards, thesharing mechanism of learning and research, for lunar data sharing needs, combinedwith the development trend of the spatial information, and is now the shortcomings ofdata sharing technology, digital lunar shared platform as the platform, set up a lunardata sharing Markup Language MDSML description of lunar data, to propose anddesign a space-based information service cloud moon-sharing mechanisms.The result of this paper include the following aspects:(1) Classification of lunar data.In-depth analysis of the characteristics of existing lunar data, according to thelunar data with massive, heterogeneous, multi-source, multi-scale, distributed andunstructured complex features, the classification of lunar data. The characteristics andrequirements of distributed lunar data storage management, and metadatamanagement to facilitate the lunar data to classify the spatial properties and spatialdata and non-spatial data.(2) Designed of the lunar data sharing Markup Language MDSML.Depth study and analysis of geospatial information, the basis of the markuplanguage in XML, GML and HGML, combined with the characteristics of lunar datafeatures and data sharing need to follow GML and HGML-grammar rules on theXML-based design and implementation of a lunar data sharing identity languageMDSML, to describe the moon spatial data and non-spatial data and the outcome dataof the moon, especially to describe the metadata information in the moon.(3) Designed a establishment of a lunar space-based information service clouddata sharing mechanism.To use MDSML moon Metadata to be identified, unified management andoperation of data registry on the moon metadata. Use data registry lunar data publishing and sharing.On the basis of research results, this paper has achieved two of the followinginnovation.(1) Proposed the language of Moon data sharing Markup Language--MDSML.Depth study and analysis of geospatial information, the basis of the markuplanguage in XML, GML and HGML, combined with the characteristics of lunar datafeatures and data sharing need to follow GML and HGML-grammar rules on theXML-based design and implementation of a lunar data sharing identity languageMDSML, to describe the moon spatial data and non-spatial data and the outcome dataof the moon, especially to describe the metadata information in the moon.(2) Proposed the Lunar data sharing mechanism base on spatial informationservice cloud.Depth study and analysis of geospatial information, the basis of the markuplanguage in XML, GML and HGML, combined with the characteristics of lunar datafeatures and data sharing need to follow GML and HGML-grammar rules on theXML-based design and implementation of a lunar data sharing identity languageMDSML, to describe the moon spatial data and non-spatial data and the outcome dataof the moon, especially to describe the metadata information in the moon.
