| Abstract: | Background graphic information base (BGIB) is the basic component of resources information system (RIS). The integrated content, the scientific structure, and the dependable precision of BGIB have closely relationship with the function playing and usage affection of RIS. Taking the creation of Shaanxi 1:250,000 BGIB of Shaanxi mineral resources information system as a case study, the paper discusses how to chose and determine the content of BGIB, and how to design and develop the structure of BGIB. Through a large number of trial studying, the author works out the optimal working flow of creating BGIB. There are three main stages that are preparing, digitizing, and checking. The principal tasks, working ways, and matters needing attention of each stage are expounded in detail by means of concrete examples. The author points out that the creation of BGIB is a systematic engineering. |
