Embodiment Construction
[0035] A. The specific realization process of field measurement data coding: When measuring the ground object data in the field, in the case of determining the realization method of the connection relationship between the ground object data points according to the shortest distance sorting method with the internal sorting method as the auxiliary method, follow Table 1 (Simplified spelling and coding structure table of various feature elements) Encode various features respectively. Table 2 lists some specific feature elements and their abbreviated spelling codes to facilitate readers' understanding.
[0036] Table 2 Part of the overall coding table representing feature elements
[0037]
[0038] In the process of encoding linear data, the internal sorting method is used to encode the complicated segment, and the distance sorting method can be used again when it is not complicated. The two kinds of encoding can be carried out interactively. In use, it is necessary to ensure that the...
