Ensure the consistency of its storage and exchange. This standard applies to the collection, storage, retrieval, analysis, output and exchange of topographic map element information in 1:500, 1:1000 and 1:2000 digital topographic maps and various spatial information systems based on them. When conducting various forms of digital mapping, various departments can supplement and extend the classification system and coding methods specified in this standard according to different professional needs and regional characteristics, or adopt classification and coding methods that facilitate conversion to this standard. code. 2 Classification and coding principles This standard uses the line classification method to classify and code topographic map element information according to the following principles. 2.1 Scientific and systematic This standard uses the current 1;500, 1:1000, 1+2000 topographic map schemas as the classification basis to adapt to the application of large-scale machine-aided survey maps, modern computer and database technology and With management as the goal, strict scientific division is carried out to form a systematic classification and coding system. 2.2 Scalability This standard sets enough containment categories so that when new information is added, the established classification system will not be disrupted. 2.3 Compatibility This standard remains basically consistent with GB13923 Classification and Code of Basic Land Information Data in terms of classification system. 2.4 Applicability While ensuring the scientific and systematic classification of topographic map element information, this standard fully takes into account the special requirements of large-scale full-field digital mapping, so that the lowest level category can be selected and recorded according to the actual conditions of field operations, making the code shorter and easier to remember. 3 Coding method Topographic information is divided into nine major categories, which are further subdivided into minor categories, primary and secondary categories. The classification code consists of a four-digit code, and its structure is as follows: X Major category A Code X Minor Class Level code x Level code Major category code, minor category code, primary code and secondary code are arranged in sequence with one decimal digit respectively.
