At present, a large number of spatio-temporal data models have been researched by scholars at home and abroad, and relevant scholars have deeper research on the service sharing of the models. The method comprises the steps of realizing geographic model sharing based on a cloud computing platform; model sharing is achieved through schemes such as meta-model design, interface design, model encapsulation and model deployment.

Research finds that the model sharing research is mainly oriented to a geographic analysis model, and the time-space data model serving sharing research is less. In the space-time data model sharing research, the dynamic feature description scheme, the model interaction strategy and the interface design research of the geographic object are insufficient, so that the space-time data model has the problems of difficult sharing and the like.

Based on this, the present invention designs a 3 DPS-based spatio-temporal data model to solve the above-mentioned problems.

Preferably, the document attributes are divided into necessary attributes and optional attributes, and the necessary attributes include: id is used for declaring the unique code of the document, type is used for describing the current document type, the value is document, parent and previous records the parent document and the front document of the current document, and version number version; optional attributes assist in recording document information, including: the document name, the author, the creation time, the modified version, the model information and the basic description can completely describe the complete content of the current geographic object space-time dynamic feature description document by defining the document attributes, and lay a foundation for the geographic object space-time dynamic description.

Preferably, the attributes of the geographic object are divided into standard attributes and extended attributes, and the standard attributes are divided into four classes, namely basic attributes, geographic attributes, data attributes and geometric attributes. In the space-time data model service sharing description scheme, the description of the geographic object attributes directly influences the application effect of the space-time data model and the dynamic expression of the space-time characteristics of the geographic object.

Preferably, the basic attribute is an essential attribute, and is used for accurately describing basic information and other information of the current geographic object, and the other information includes id, parent, previous, version and description.

Preferably, the geographic attribute is a core attribute of the geographic object, the geographic attribute includes a geographic sub-attribute, the geographic attribute includes an attribute position, a direction orientation, a coordinate system and a camera view camera of the geographic object position, and the sub-attribute includes a positioning dependent attribute, a positioning independent attribute, a heading, a pitch and a roll. The location-dependent attribute is a single-point location, that is, the location of a certain entity is determined by a single coordinate, and the geographic entity using the location-dependent attribute is usually a point, a character, a model, or the like. Entities that use location independent attributes are typically lines, planes, etc. The coordinateSystem is used for accurately describing data coordinate system information, and the attribute is processed through a model function, so that data of different coordinate systems can be uniformly expressed. A camera view camera for determining a camera orientation.

Preferably, the data attribute is used to describe a data source and its own attribute information: address url, type, parameter, time clock, and description. The relevance among all the attributes in the data attributes is strong, namely the modification of the current attribute often influences the change of other attributes, so that the scheme adds a restriction relation to all the data attributes, namely after a certain attribute value changes along with the time, other restricted relation attributes also change along with the change of the attribute value. The data attribute is a core attribute of the geographic object space-time dynamic feature description scheme supporting the multi-source heterogeneous data, and the dynamic expression of the multi-source heterogeneous data in the geographic scene is realized through the integrity design of the attribute.

The geometric attributes are 15 categories in total, each attribute comprises sub-attributes, and some sub-attributes are basic sub-attributes including position, material, border, color and the like. Still others are used to control how smooth the geometry is to extend the child property, granularity, resolution.

Preferably, the extended attributes of the geographic objects are to express more complex geometric models and to extend the high level functionality of the description schemes, and can be defined by the application needs of the user in a customized manner. When defining the extended attribute, the user-defined prefix is required to be identified before the extended attribute so as to avoid the conflict with the document attribute and the geographic object standard attribute.

Preferably, the document sub-package design and the stream transmission mechanism are designed to unpack the spatio-temporal data description documents, the stream transmission is performed by combining SSE, each time a client receives a packet, an event is triggered, a large amount of spatio-temporal data description documents are processed in a stream mode, the significance is that when a large amount of space-time data is processed, the client can progressively acquire, transmit and process data with changed space-time dynamic characteristics of the geographic object, the visualization effect of real-time data is improved, when the space-time data describes the dynamic change of the geographic object, the change of single or complex attributes of the same object or the change of single or complex attributes among a plurality of objects can occur, aiming at the complexity of the situation, the research proposes to adopt the geographic object id to realize the association between the packages, i.e. each package comprises one or more attributes of the geographical object id, other attributes that need to be changed can be stored in the same package or between different packages. Therefore, in some cases, dynamic changes of a certain geographic entity can be described by multiple packets. How to control the data volume of each packet in the subpackaging process to adapt to the efficient visualization of the client is one of the key problems in the subpackaging process. The change attributes of the geographic entities all define render attributes, the attributes indicate the complexity of the current geographic object attribute change rendering, the higher the coefficient is, the greater the requirement on the required client visual rendering capability is represented, and therefore, the data volume of each packet needs to be reduced during sub-packaging so as to balance the rendering pressure of the client. For geospatial objects which dynamically change with time, the attributes such as spatial positions and the like of the objects change with the lapse of time, and the description documents of the spatiotemporal data are increased. The excessive data volume can cause the network transmission to be limited and the client to be difficult to analyze, and can affect the real-time or near real-time dynamic expression.

The Modlstart interface is used for starting a model (chain), and a user needs to provide a model (chain) model ID parameter and a controlType control type parameter under the interface so as to realize the control of the model in the service platform.
