Electronic map frame data updating method

Abstract

The invention provides an electronic map frame data updating method. The method is characterized in that on one hand, the method solves the problem that editing efficiency becomes lower due to the fact that geographic elements needing to be modified are increased when element conflicts exist in traditional spatial database version editing and mass data need to be edited, multi-user and multi-version concurrent editing is achieved, and the method is a novel updating operation method without data segmentation and edge matching; on the other hand, an increment updating information recorder is introduced for comprehensively and automatically recording information of updated content, such as operators, operation time and operation types (adding, deleting and modifying). A good basis is established for later statistics and analysis of updating conditions through automatic recording of updating information, and the workload condition can be effectively controlled.

Description

technical field [0001] The invention relates to the field of updating frame data of an electronic map, in particular to a method for updating frame data of an electronic map. Background technique [0002] The current status of electronic map frame data is one of the important symbols to measure its use value. How to ensure the current status of this kind of data has become an important challenge faced by surveying and mapping departments and the GIS industry. The technology and strategy of electronic map frame data update has also become a research hotspot in academic circles and industrial units. [0003] The process of the traditional electronic map frame data update method is as follows: first, cut out the data to be updated from the source data (that is, the data to be updated) according to the scope of the change, and after all the data to be updated is updated, it is then compared with the original data. The changed areas are border-joined, and finally the frame d...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for updating the frame data of an electronic map, which solves the problem of element conflicts in traditional spatial database version editing and the low editing efficiency caused by the increase of modified geographic elements when editing massive data , so as to truly realize multi-user, multi-version concurrent editing, and a new update operation method that does not need data block and edge connection; at the same time, it solves the problem that the traditional operation method cannot record the update content, which leads to the inability to realize the incremental update of spatial data and the inability to Problems with stats updates
