Description

Technical Field

[0001] The utility model relates to the technical field of geographic information measurement, and particularly relates to a GIS-based geographic information measurement benchmark device. Background Technique

[0002] GIS (Geographic Information System) is a technical system that collects, stores, manages, calculates, analyzes, displays, and describes relevant geographic distribution data in the entire or part of the earth's surface space under the support of computer hardware and software systems. The geographic information measurement benchmark device is a tool for positioning and auxiliary measurement when using GIS for geographic data measurement. This device combines mechanical structure design (such as support rods, lifting rods, fixing structures, etc.) and the relevant technical requirements of geographic information measurement, aiming to meet the measurement needs in different geographic environments and improve the accuracy and convenience of measurement.

[0003] The Chinese patent provides a positioning benchmark with a publication number of CN218628350U, which includes a first rod body, a second rod body, and a straightness detection mechanism. The first rod body and the second rod body are coaxially arranged, and one end of the first rod body and one end of the second rod body are detachably connected; the end of the first rod body away from the second rod body is a conical end, and the end of the second rod body away from the first rod body is detachably connected to the straightness detection mechanism. The straightness detection mechanism is used to assist the first rod body and the second rod body to be vertically inserted into the ground plate after combination. One end is respectively connected to both ends of the push-pull plate, and the other end is respectively connected to the glue application roller and the auxiliary roller.

[0004] In the above device, the first rod body and the second rod body are combined before insertion, and the straightness detection mechanism is used to assist the staff during insertion, so that the staff can insert the positioning benchmark straight into the area to be surveyed and mapped, ensuring the accuracy of measurement data. However, this device only directly inserts the positioning rod into the bearing surface. If the soil quality of the bearing surface is soft, it will cause the positioning rod to be unstable during installation, resulting in measurement deviation. Therefore, a GIS-based geographic information measurement benchmark device is needed. Content of the Utility Model

[0012] Preferably, the lifting blocks are located inside the lifting grooves, and the connecting frame is slidably connected to the lifting sleeve through the cooperation of the plurality of lifting blocks and the lifting grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
