Example Embodiment
[0045] The specific embodiments and working principles of the present invention will be described in further detail below with reference to the accompanying drawings.
[0046] Such as figure 1 As shown, a method for integrated management of spatiotemporal data based on chain storage, the specific steps are as follows:
[0047] Step 1: Analyze the original data, create a chain storage structure, use the chain storage structure to establish the chain relationship between spatiotemporal data elements in different temporal versions, and form a spatiotemporal data link;
[0048] Such as figure 2 As shown, the chain storage structure includes four fields GUID, Time, OldGUID, and Status. The GUID field is used to store the global unique identifier of the current tense of the spatiotemporal data element, and the Time field is used to store the spatiotemporal data element. The time of adding, deleting, or editing, the OldGUID field is used to store the globally unique identifier of the last ...
