<p>Historical architecture is of great significance to the continuation of urban historical context, and it is an important part of cultural heritage. The general survey and identification of historical buildings is the basis and support of the protection and utilization of historical buildings. However, the existing working methods and technical means are relatively backward, it can not reflect and record the value characteristics and basic information of historical buildings truly and completely. These backward means have led to the inefficiency of the general survey and identification of historical buildings, which has also led to the fact that the results of the general survey can not be digitized and difficult to refer to. This paper analyzes the problems existing in the traditional methods of general survey and identification of historical buildings, and constructs the basic technical support of the general survey and identification of historical buildings from the aspects of general survey and identification standard system, investigation and data processing tool system, operation guidance system and so on, which is based on the technical requirements and the secondary development of GIS, taking the general survey and identification of historical buildings in Beijing as an example. It is hoped that this paper can convey our thinking and research results to our professional colleagues. In addition, we look forward to the promotion and application of this method, so as to promote the protection and management of cultural heritage towards comprehensive data.</p>
