5.2.3 The surrender shall ensure that the transfer of data accuracy, completeness, requirements are as follows:

a) Construction of the required data should be aligned

5.1.4 integration, and to establish a linear relationship between the transactions;

b) Construction of the pipe centerline and along the coordinate precision feature should achieve sub-meter accuracy. In densely populated areas data should be raised Accuracy.

5.3 Data storage and update

5.3.1 Reference should be linear attributes pipeline system for organizing and maintaining data, data can not be incorporated into the linear system based on the coordinates To save.

5.3.2 should be structured entity data model, to achieve data lifecycle management and effective maintenance.

5.3.3 should be stored structured data by building a database for storing data based model. Storing unstructured data

5.3.4 documents, pictures, video and other files list should be established. Unstructured data should ensure submission of data and documents Listing consistent.

5.3.5 Management measures should be taken to ensure data accuracy and timeliness.

5.3.6 embodiment should have the data and updates data verification methods, preferable to use the updated data or the verified.

5.3.7 Data Update should meet the following requirements. Data

a) storing the routine should check to ensure consistency and integrity;

b) updating the facility information, for example, coating or pipe section replacement should be collected and stored;
