Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping boards, in particular to a surveying and mapping board for highway bridge survey and design. Background Art

[0002] Surveying and mapping literally means measuring and drawing. It is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as the technical core. It selects existing feature points and boundaries on the ground and obtains graphics and positions reflecting the current status of the ground and related information through measurement methods for the use of engineering construction, planning and design, and administrative management. Surveying and mapping refers to the measurement, collection, and mapping of the shape, size, spatial position, and attributes of natural geographical elements or artificial facilities on the surface. With the development of social economy, the country has begun to vigorously carry out infrastructure construction. Generally, before the construction of highway bridges, it is necessary to survey the construction site, and surveying and mapping personnel will draw surveying drawings for design. Outdoor surveying and mapping generally uses surveying and drawing boards and support frames. Usually, surveying and mapping boards are large, which are very inconvenient to use outdoors.
