Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of geographic information processing, and in particular to an online and offline collaborative processing system for geographic information data. Background Art
[0002] With the continuous development of natural resource survey and monitoring, the accuracy and timeliness of geographic information data surveys are increasingly required. The traditional geographic information data processing methods are mainly 1. online collection and processing, 2. online collection, offline processing (no data collaborative processing system), 3. offline collection and processing. Any of the above methods has problems such as complex management, difficulty in multi-user collaboration, and low resource utilization. For example, relying on online collection and processing methods will lead to a large amount of key sensitive data in the intranet environment cannot be shared and used, reducing the quality requirements of the results data; relying on online collection and offline processing (no data collaborative processing system) methods is prone to data conflicts and chaotic management. The relationship between online collection and offline processing must be strictly coordinated, such as collection during the day and online processing at night, etc. Time-sharing isolation methods, but this is only suitable for simple small-scale geographic information survey operations. For geographic information surveys in complex scenarios such as large amounts of data and multiple regions in a short period of time, it is difficult to maximize work efficiency by relying solely on time management, and the complexity of management will increase exponentially. At the same time, once an emergency occurs, such as rain the next day, all collection and processing work must be rearranged according to the weather and progress at the time. The management is extremely difficult, and the number of collection and processing personnel is difficult to predict. In addition to the disadvantages of online collection and offline processing, offline collection and processing methods also have problems such as the inability to monitor the collection process in real time. Summary of the invention
[0003] The purpose of the present invention is to provide an efficient, accurate, multi-user online and offline collaborative processing system for geographic information data, aiming to solve the problems of difficult data fusion, complex task relationship management, low operating efficiency, etc. caused by the differences in working environment, purpose and operation mode between the two processes of geographic information data collection and data processing.
[0004] To achieve the above objectives, the present invention adopts an online and offline collaborative processing system for geographic information data, including a geographic information mobile phone collection terminal, an online data management system, a data quality inspection system, and an online and offline data fusion system.
[0005] The geographic information mobile phone collection terminal is used to receive the issued tasks in real time, and collect and edit photos and attribute data at the corresponding location in the field, and upload them to the system.
[0006] The online data management system is used to manage geographic information data tasks, including importing and issuing task spots, real-time monitoring of task status, batch editing of data, batch export of data, etc.
[0007] The data quality inspection system is used to perform quality inspection on data exported from the online data management system and processed by offline professional geographic information software before uploading to the system, including data structure verification, threshold inspection and numerical distribution statistical analysis.
[0008] The online and offline data fusion system is used to automatically fuse offline data that has passed the data quality inspection system with the latest online data.
[0009] The present invention provides an online and offline collaborative processing system for geographic information data. When used, first, the administrator uploads the map task to be collected through the online data management system, including the geographic location, photo field, and attribute field, and issues the task in different regions according to the area to which the map belongs. The user views the task map through the geographic information mobile phone collection terminal, and goes to the corresponding actual location to take photos, check the existing attribute information, and add new information. Offline data processing personnel can copy the data exported through the online data management system to the internal network environment offline, and use GIS software to overlay other thematic spatial data for spatial analysis, assignment, graphics processing and other operations. The processed data is imported into the data quality inspection system for pre-return inspection to check the data consistency and completeness. After the inspection is qualified, the online and offline data fusion system is used to compare and return the data record by record and field by field. In this way, the advantages of online collection in the field and offline processing in the office can be fully utilized, and operations can be performed simultaneously, which reduces the complexity of coordination between internal and external personnel, improves organizational efficiency, and shortens project progress.

[0015] In practical applications, the geographic information mobile phone collection terminal can use a customized mobile application running on a smart phone. The online data management system can be deployed on a cloud server and communicate with the online database through the network. The spatial database can use a relational database that supports geographic spatial types. The data quality inspection system can use a custom-developed application that supports a rule library and configure field inspection rules. The field inspection rules include field type verification, threshold verification, spatial relationship verification, etc. The online and offline data fusion system uses a single record and single field comparison judgment. The system compares the business layer data (after offline processing and quality inspection), business layer data (original), and business layer data (online version) at the same time. According to the data comparison, it is divided into online updated fields, offline updated fields, and online and offline updated fields at the same time. When only the online or offline updated fields are used, the updated values are taken; when the fields are updated both online and offline, they are divided into online priority fields (such as photo fields), offline priority fields (such as spatial graphic fields) and non-priority fields (such as update time, mark deletion fields) according to their priorities. The online priority fields take the online updated values, the offline priority fields take the offline values, and the non-priority fields define the final values according to the value size and other rules to form an updated value sequence, generate and run the corresponding update sql update statement, and achieve the effect of real-time integration of online and offline. Through this system architecture, the whole process of geographic information data from collection to processing, quality inspection and integration can be realized, without the need for online and offline operators to wait for each other, which greatly improves the efficiency and quality of geographic information data processing and reduces the complexity of management.
