Description
Technical field
The present invention relates to wisdom urban geographic information access technique field, relate in particular to a kind of polynary remote sensing observations data andThe method of the unified access of metadata information.
Background technology
Along with geographic information data coding standard development, the metadata schema of observation data is constantly improved. GML(GeographyMarkupLanguage) be geographical indication language, it is by OGC(Open Geographic Information System association) inWithin 1999, propose, within 2007, GML has been updated to 3.2 versions. GML is the application of XML in geospatial information field, definitionThe structure of geometric attribute, coordinate attributes, topological relation, observation, coverage attribute, can represent geographical space objectSpatial data and non-space attribute data. But GML metadata schema is loosely organized, meticulous not, and level of abstraction is higher. ForSupport observation data coding, 2007, Open Geospatial Consortium issued general observation and has measured encoding model 1.0 editionsThis. General observation and a kind of general observation data encoding mechanism of having measured encoding model 1.0 version definition, but this codingModel universality is higher, cannot become more meticulous and describe the abundant metadata information of remotely-sensed data. 2010, Open Geospatial ConsortiumIssue general observation and measure encoding model 2.0 versions. General observation with measure encoding model 2.0 versions provide observation withMeasure the careful metadata schema of encoding model 1.0, but it is still not enough to the meticulous abundant first number of description remotely-sensed data that reachesIt is believed that the requirement of breath.
Remotely-sensed data carries abundant metadata information. When obtaining, remotely-sensed data have corresponding sensor, sensor to put downStation information, corresponding with sensor have sensor type, resolution information, an observation attribute information. Remotely-sensed data has correspondingCoverage information, coverage can be polygon, can be also specific rectangle. Corresponding with polygon have summit, inThe geographical coordinate information of heart point. There is address information the chained address of remotely-sensed data, also has the quick browsing information of address information. RemoveOutside this, except basic information, also comprise product hierarchy, the data center of data storage, the data lattice of observation dataFormula, the information that obtains data product, the spectral characteristic type of product, the archive information of product.
General observation is encoded a kind of general coded system is provided for observation data with measuring coded system, provides a descriptionThe ability of metadata information of general observation data, but in encoding model element type can only to describe observation data generalAttribute type, as observation data, observation attribute, coverage, observed result, the type in its metadata schema is abundant not,The structure of metadata schema is meticulous not. Therefore, observation and measurement encoding model expression metadata information is limited in one's ability. ForImprove the ability to observation data metadata information coding, 2012, Open Geospatial Consortium proposed one and has seen over the ground numberAccording to encoding model, this encoding model derives from general observation and measurement encoding model 2.0, and this coded system is remotely-sensed data productCoding provides a set of general coding rule, has provided specific definition and example especially for metadata encoding. Earth observationIt is upper that encoding model is used in earth observation data product coding, as from satellite, and the earth observation number that aircraft, fire balloon getAccording to. Earth observation encoding model provides abundanter, and finer metadata description rule has greatly improved to describe over the ground and seenSurvey the ability of data metadata information. But, too redundancy, numerous and diverse of element in this remotely-sensed data coding structure, Partial ElementsType can not occur substantially in general actual coding, as Doi element (for identifying the digital object identifier of product),VendorSpecific/SpecificInformation/localAttribute element (container of special metadata, notBe worth with particular task or expansion), vendorSpecific/SpecificInformation/localValue element(the container of special metadata is unworthy with particular task or expansion), orientation element (determines that satellite coversThe right direction of the lid polygonal outline coordinate in region). Therefore earth observation encoding model structure is slightly aobvious numerous and jumbled, refining not.
Comprehensive analysis, there is following problem in current polynary Remote Sensing Data Access method:
(1) scarce capacity of the metadata information of general observation and the polynary remotely-sensed data of measurement Coding and description. Earth observationThe metadata information of the observation data of sensor is abundant, comprises observation time started, observation end time, observation attribute, observationPlatform, observation sensor type, observation sensor resolution ratio, observation coverage, key element interested, observed result, and at presentThe specific aim of metadata information of the polynary remotely-sensed data of description not strong. General observation and measurement data coding method have pervasiveProperty, its level of abstraction high, metadata schema that code element type is general can not meet polynary remotely-sensed data unit number preferablyAccording to information coding to becoming more meticulous, the demand of the metadata schema that code element type is abundant.
(2) observation data encoding model is described the metadata information ability surplus of polynary remotely-sensed data. Earth observation numberAbundant according to element type in encoding model structure, there are 70 kinds of element left and right, extremely element type refinement, abundant is passable for theseMeet the metadata information of describing polynary remote sensing. But the lengthy and tedious structure of earth observation encoding model has exceeded polynary remotely-sensed data to be compiledThe complexity of code book body, has brought barrier to polynary remotely-sensed data coding, is not suitable with the unified access of polynary remotely-sensed data.
Summary of the invention
