Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping tools, in particular to a geographic information surveying and mapping ruler. Background Art

[0002] Geographic information mapping is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It includes topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, and investigation of reserve resources such as barren hills and wastelands. Surveying equipment and surveying scales are often used when mapping geographic information.

[0003] For example, in the utility model patent "A Telescopic Surveying and Mapping Ruler" with publication number CN219694021 U, an inner ruler is telescopically and slidably connected to one side of the outer ruler, and a flush ruler is movably connected to the top of the inner ruler. The inner ruler and the flush ruler can be moved and retracted into the outer ruler. After the inner ruler extends out of the outer ruler, the flush ruler moves up to be flush with the top of the outer ruler. After the surveying and mapping ruler of the utility model is extended, the flush ruler moves up to make the overall scale lines flush, avoiding measurement errors caused by visual errors.

[0004] However, in the above-mentioned prior art, when measuring, the surveyor observes and records the data on the ruler. The ruler is held and erected by the operator, and the verticality is difficult to ensure. In addition, the surveying process is long, and the operator is prone to fatigue when holding it for a long time. Utility Model Content
