Geographic information engineering surveying and mapping device

Abstract

The invention discloses a geographic information engineering surveying and mapping device. The geographic information engineering surveying and mapping device includes a main measuring plate, a longitudinal leveling instrument, a transverse leveling instrument, a measuring instrument base fixing groove, a protractor, a gravity pendant, a universal coupling A, a movable round base, a telescopic supporting rod, a horizontal base, a laser lamp base, a laser lamp hole, a laser lamp rod, a laser lamp frame, a small laser lamp, a measuring instrument base, a universal coupling B, a measuring instrument base fixing rod, a locking bolt and a jackscrew. According to the geographic information engineering surveying and mapping device, through the arrangement of the telescopic supporting rod and the horizontal base, adjustment can be conducted according to the horizontal placement condition, and the placement levelness is guaranteed; due to the arrangement of the horizontal detection bead, horizontal detection is facilitated, and the accuracy of surveying and mapping data is ensured; the device can be used in a place with a large fluctuation difference, and has the capability of simple measurement and the capability of simultaneous transverse and longitudinal adjustment.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a geographic information engineering surveying and mapping device. Background technique [0002] Surveying and mapping is the study of surveying and mapping to measure and calculate the geometric position of ground points, the shape of the earth and the earth's gravity field, based on which the natural shape of the earth's surface and the geometric distribution of artificial facilities are measured, and combined with the geographical distribution of certain social information and natural information, to compile a global The theoretical and technical disciplines of maps and thematic maps of various scales and local areas, in order to facilitate on-the-spot investigations, are usually fixed with a tripod, measured and recorded by advanced instruments. [0003] Commonly used instruments are all fixed by tripods, the length of the tripods used is fixed, most o...

AI Technical Summary

Problems solved by technology

[0003] Commonly used instruments are all fixed by tripods, the length of the tripods used is fixed, most of them do not have the ability to expand and contract, and are inconvenient to use in places with large fluctuations in height and height, and the measurement capabilities are all from surveying and mapping instruments, which do not have the ability to measure easily. And the angle adjustment ability is low, and it does not have the ability to perform horizontal and vertical adjustments at the same time
