Description

Technical Field

[0001] The utility model relates to the technical field of urban surveying and mapping investigation, in particular to a measuring bracket for urban surveying and mapping investigation. Background Art

[0002] With the widespread adoption of digital mapping technology and the continuous development of GIS, urban topographic maps have evolved from simple digitization to informatization, marking a significant leap forward for urban surveying and mapping towards the modern geographic information industry. Topographic map databases are the foundational databases of urban geographic information systems and a crucial strategic resource for urban informatization, with widespread application in urban construction and management. Currently, with the development of "digital cities," the demand for basic geographic information across various urban industries is increasing, making the construction of urban topographic map databases increasingly important. Therefore, urban surveying and mapping departments should seize this opportunity, forge ahead, and continuously improve the construction and application of urban topographic map databases in my country.

[0003] For example, the surveying stand for urban planning research disclosed in authorization publication number CN218409124U includes a surveying stand body, a support leg rotatably connected to the right inner surface of the surveying stand body, a reversibly threaded rotating rod provided on the right inner surface of the surveying stand body, a clamping block threadedly connected to the outer wall of the reversibly threaded rotating rod, a curved clamping plate clamped to the inner surface of the upper end of the clamping block, and a slider slidably connected to the right inner surface of the support leg. This surveying stand for urban planning research utilizes two different mounting methods—the clamping block and the curved clamping plate—as well as a top plate limiter, allowing the surveying stand to be mounted and fixed to various types of measuring instruments. The slider drives the ground-mounted spikes to adjust and extend, thereby lengthening the support legs, allowing the length of individual support legs to be adjusted individually. This allows the surveying stand to adapt to different terrains and level the stand, improving the accuracy of measurement data and facilitating urban planning research. However, it is difficult to stabilize and secure during use, and the device is relatively complex and inconvenient to use. Therefore, we propose a surveying stand for urban surveying and mapping research. Utility Model Content
