Preface

With the development of China’s economic construction and society, as well as the continuous emergence of new science and technology, the demand for surveying and mapping results is increasing. Surveying and mapping projects show the characteristics of large production scale, high investment amount, high technical requirements, complex construction process and so on. In order to ensure that the surveying and mapping project is completed on time and with high quality, it is difficult for the investor to supervise and manage the project. With the continuous improvement of China’s laws and regulations, the deepening of socialization, specialization, standardization and normalization of engineering supervision work, and the continuous improvement of engineering supervision system, more and more investors choose to supervise and manage surveying and mapping projects with the help of social professional forces.
         In the process of engineering project construction, the level of engineering measurement is the most direct factor affecting the quality of engineering project construction. High level and high quality of engineering measurement is of great significance to ensure the smooth progress of engineering project construction and improve the quality of engineering construction. In order to effectively improve the technical level of engineering survey, we should strengthen the application of advanced surveying and mapping technology, such as digital surveying and mapping technology, whose technical advantages are very prominent. When applied in engineering survey, it can provide strong technical support for engineering survey, ensure the efficient development of engineering construction projects, and improve the quality of engineering construction. Compared with traditional surveying and mapping technology, digital surveying and mapping technology is more accurate and faster. The accuracy of measurement results is very important for a project, which is related to the quality of a project. Therefore, digital surveying and mapping technology not only improves the efficiency of Surveying and mapping in engineering construction, but also helps to improve the quality of the project.

前 言

随着我国经济建设和社会的发展以及新的科学技术的不断出现，对测绘成果的需求日益增强，测绘项目呈现出生产规模大、投资额度高、技术要求高、施工工序复杂等的特点。为了保证测绘项目按时并高质量地完成，单纯由投资方对项目进行监督管理有一定的难度。而随着我国法律法规的不断完善，工程监理工作社会化、专业化以及规范化、正规化的不断深入，工程监理制度不断完善，投资方越来越多地选择借助社会专业力量对测绘项目进行监督管理。
        在工程项目建设过程当中，工程测量水平高低是影响工程项目建设质量最为直接的因素，高水平、高质量的开展工程测量工作，对保证工程项目建设顺利进行，提高工程建设质量意义重大。为了有效提高工程测量技术水平，应当加强先进测绘技术的应用，如数字化测绘技术，其技术优势非常突出，应用于工程测量中，可以为工程测量提供强大的技术支撑， 保证工程建设项目高效开展， 提高工程建设质量。数字化测绘技术相较于传统的测绘技术测量更加精准，测量速度更快。测量结果的准确性对于一项工程来说是十分重要的，关系着一个工程质量的好坏，所以数字化测绘技术不仅仅提高了工程建设中的测绘效率，而且还有利于提高工程质量。
