Embodiment Construction
[0035] A. The specific implementation process of field measurement data coding: when measuring ground object data in the field, in the case of following the shortest distance sorting method with the internal sorting method as an auxiliary method to determine the realization method of the connection relationship between the ground feature data points, according to Table 1 (Simply spelled coding structure table of various features and features) Coding various features of features respectively. Table 2 lists some specific feature elements and their simplified codes for the convenience of readers.
[0036] Table 2 Partial representation of the overall coding table of features
[0037]
[0038] In the process of encoding linear data, the internal sorting method is used for encoding when encountering complex segments, and the distance sorting method can be used for encoding when it is not complicated. The two encodings can be performed interactively. In use, it is enough to ensu...
