A Business Model-Driven Approach To Real-Time Capture Of Land Use Changes

After land survey database is constructed, we should use the scientific method to ensure its currency. At present, land survey database relies on the land change survey to keep updating, which is based on remote sensing changed pixel. This works with the annual cycle, high complexity, heavy workload, and the data update cycle is so long, hard to maintain its currency. It is ideally that the land change data can be captured quickly and the change information can be dynamic updated daily, through management and technology innovation. These are one of the important development trends of the current land survey and update job.With the gradual improvement of land information construction, all aspects of land business are covered by the information systems with high degree of standardization. Land use changes are according to strict examination and approval processes, and business systems associated with those processes record the change of land use information, changes out of examination and approval would be recorded by land law enforcement or other business system. Land use changes can be extracted in real-time by technology to monitor the business system database. This issue is just based on the idea above. Firstly, we sort out the land business data flow, find out the key link of land use changes, and determine the change source. Then design and realize technology to acquaint、storage、exchange spatial and non-spatial data. Lastly, apply the technology scheme to a real single land business link, listen to feedback and perfect it.The research results can be concluded into two aspects:①It is feasible to access the change data from the land management business systems in real-time and daily update business-driven land use data dynamically and continuously. With the wide application of the ideas in the land and resources management departments, the existing land change survey method can be complemented greatly.②After experimental validation, it can be found that the real-time access technology of land change information based on business-driven could achieve the discovery, capture, organization and exchange distribution of change data spatial or non-spatial. The technology can be applied to the change of land data. It can effectively shorten the change cycle and reduce the cost of changing in land survey database.
