1 Subject content and scope of application
This standard specifies the basic requirements, main contents and approval procedures for surveying and mapping technical design. CH/T 1004—1999
This standard applies to the technical design of mandatory and guiding surveying and mapping tasks, and market regulation tasks can be implemented as a reference. 2 General provisions for technical design
2.1 The purpose of technical design is to formulate practical and feasible technical solutions to ensure that surveying and mapping products meet technical standards and user requirements and achieve the best social and economic benefits. Therefore, each surveying and mapping project must be technically designed before operation. The technical design book shall not be implemented without approval.
2.2 Technical design is divided into project design and professional design. Project design refers to the comprehensive design of surveying and mapping projects with complete surveying and mapping process content, whose products can be directly used and circulated by the society. Surveying and mapping projects include geodesy, topographic survey, map making and printing, engineering survey and multi-purpose cadastral survey basic data surveying and mapping. Professional design is a specific technical design based on the project design and according to the type of work, and is the main technical basis for guiding the operation. The project design is written and reported by the competent department responsible for the mapping task, and the professional design is written and reported by the surveying and mapping production unit. The design work can be entrusted to the surveying and mapping design unit, or it can be written by full-time designers. 2.3 The basis and basic principles of technical design
2.3.1 The basis for technical design

Production quotas, cost quotas and equipment standards for surveying and mapping products. Basic principles of technical design
The technical design plan should consider the whole first and then the part, and take into account development; it should meet the requirements of users and attach importance to social and economic benefits. b.
Starting from the actual situation of the operation area, considering the strength of the operation unit (personnel technical quality and equipment conditions), tapping potential, and selecting the best operation plan.
Extensively collect, carefully analyze and make full use of existing surveying and mapping products and data. d. Actively adopt applicable new technologies, new methods and new processes. The size of a design area is generally completed in 1 to 2 years. Projects with large workloads , the operation area can be divided into several small areas, and technical design can be carried out separately; if the workload is small, project design and professional design can be combined. 2.4 Requirements for designers
2.4.1 Designers must first clarify the nature of the task, workload, requirements and design principles. 2.4.2 Designers should carefully conduct field surveys and investigations and analyses of the operation area. 2.4.3 Designers should be responsible for their design documents, go to the front line to check and understand the correctness of the design plan, and deal with problems in a timely manner when they are found.
