The Shortest Distance Sorting Method Supplemented by Jipin Coding Method and Internal Sorting Method for Digital Mapping

Abstract

The invention discloses a minimum distance sorting method assisted by a digital mapping brief spelling coding method and an internal sorting method, which is directly applied in the technical field of the total field digital mapping. The brief spelling coding method is composed of a type code+ (a series number)+ (a descriptor)+ (a feature code)+ (-an attribute code)(contents in the brackets are selectable), wherein the measured data is sorted by the minimum distance sorting method assisted by the brief spelling coding method. The minimum distance sorting method is as follows: sequentially calculating distances between the base point and the rest points from the starting point of the surface feature data point and taking the starting point of the surface feature data point as the base point, and selecting the data point with the shortest distance as the connection point with the base point, and taking the selected point with the shortest distance as the base point again, and sequentially calculating the distances between the base point and the rest points, and selecting the data point with the shortest distance as the connection point with the base point, and repeating the steps until no rest points are left; finally, sorting the data points with the shortest distances from each selection based on the precedence such that the sequence fully ensures the connection relationship between each surface feature data point and the other points. The minimum distance sorting method can achieve full automation on field mapping fast coding and interior data processing and map making.

Description

Technical field: [0001] The patented technical solution of the present invention belongs to the category of surveying and mapping science, and is directly applied to the technical field of digital surveying and mapping in the field. The field surveying map can be realized by using the simplified coding method in the patent and the shortest distance sorting method with the internal sorting method as an auxiliary method Fast coding and full automation of office data processing and graphics. Background technique: [0002] In the field of all-field digital mapping, the complexity of field object information determines the diversity of data encoding schemes in all-field digital mapping software currently used in the surveying and mapping industry. The currently widely used data coding schemes are: 1. Block structure coding scheme. The mainstream software using the block structure coding scheme is Tsinghua Shanwei’s EPSW electronic flat panel system. Sketches have relatively low ...

Problems solved by technology

[0003] A. Purpose of the invention: the shortest distance sorting method supplemented by the Jianpin coding method and the internal sorting method is to solve the difficulty in remembering the codes in the various coding schemes in use above, and the slow input coding speed in the field, which cannot fully satisfy the crossover of multiple instruments. It is carefully developed due to the needs of the operation, there is no clear coding connection information, or there is a method of clearly coding the connection information but it is difficult to operate.
