Dynamic updating method and apparatus for integrated plan and graph

Abstract

The invention provides a dynamic updating method for an integrated plan and a graph. The method comprises the steps of extracting achievement data from an achievement database according to a captured demand adjustment instruction, and generating a rule modification base drawing, wherein the achievement data is parcel map spots, the parcel map spots have additional attributes, and the additional attributes include a global identifier code and a timestamp; receiving editing operation on the plan modification base drawing, updating the parcel map spots of the plan modification base drawing according to the type of the editing operation, and performing storage to obtain plan compilation achievement data; and capturing updating and storage operations, performing two-way circular comparison on the plan compilation achievement data and the achievement database according to the global identifier code and the timestamp, and realizing storage of the plan compilation achievement data and updating of the achievement database. The invention furthermore provides a dynamic updating apparatus for the integrated plan and the graph. The frequent achievement updating demand of the integrated plan is met and the scientific standard ordered management is realized.

Description

technical field [0001] The invention relates to the field of geographic information, in particular to a method and device for dynamically updating "multi-plan integration" and "one map". Background technique [0002] "Multi-plan integration" refers to strengthening the connection and coordination of various plans such as urban and rural planning, overall land use planning, and environmental protection planning based on national economic and social development planning, and delineating ecological control lines on a unified spatial scale , Basic farmland control lines, urban growth boundary control lines, and industrial block control lines, etc., to achieve the goals of optimizing urban and rural spatial layout, effectively allocating land resources, promoting economical and intensive use of land, and improving government administrative efficiency. As an important means of researching and exploring the spatial planning reform of cities and counties, "integration of multiple pl...

Problems solved by technology

Although this traditional overall update method can solve the periodic and annual update requirements, it cannot solve the daily update requirements well. The existing technology adopts the overall layer update operation method, which has the following disadvantages :

[0006] First, the result update period is long, which cannot meet the regular update requirements of the "multi-plan integration" construction project site selection and the "one map" conflict. The entire layer has a large range, a large amount of data, and a long modification time. The examination and approval of the construction project of planning and planning requires rapid adjustment and improvement

[0007] Second, planners and database managers need a lot of communication and docking work to complete the description of data updates, and the work efficiency is very low

After the modification of the data of the same layer is completed, the planner needs to explain to the database manager whether the modification is done one by one. The modified map needs to explain what information has been modified, and the update verification workload is heavy.

[0008] The third is that after the results are updated and stored in the database, other people can only use the latest results, and it is difficult to quickly know the detailed update status of the two sets of results before modification and after modification

Historical results are not stored or stored in the form of historical layers, so quick version comparison at any time is impossible, and the difference information between versions needs to be manually identified

[0009] Fourth, it is often impossible to grasp whether the compilation unit has revised the plan based on the existing "one map" results, and the existing data is not fully utilized or the planning is not based on the latest data.

When the compilation unit does not adopt the existing unified "one map" results, when coordinating and handling the planning contradictions within the project scope, the different data versions may cause contradictions in other land plots outside the project scope, which will bring new problems to the data update work. unintended serious consequences

[0010] Fifth, both modified and unmodified patches in the update layer are stored multiple times, resulting in large redundancy of database storage and waste of resources
