Geographic information mapping system

Abstract

The invention belongs to the technical field of geographic mapping, in particular to a geographic information mapping system. The geographic information mapping system comprises a machine body, wherein two sides of an upper surface of the machine body are rotationally connected with a connection shaft through a rotary shaft; an upper end of the connection shaft is connected with a protection shellthrough the rotary shaft; a movable slot is formed at the center of the upper surface of the machine body; an upper end of the movable slot is connected with a movable shaft through rotary connection; an upper end of the movable shaft is fixedly connected with a handle; a support base is rotationally connected to the center of a bottom end of the machine body through the rotary shaft; a bottom end of the support base is rotationally connected with a No.1 rod through the rotary shaft; one side surface of the No.1 rod is fixedly connected with a fixed shaft; a protection shell is arranged on the periphery of the outside of a precise instrument at an upper end of a mapping instrument for protecting the precise instrument and preventing the mapping instrument from being damaged under the action of external force; one side of each of support rods at three positions of the bottom end of the mapping instrument is provided with a retractable wheel; and a movable handle is arranged at the upper end of the mapping instrument. The geographic information mapping system is easy to retract, and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of geographic surveying and mapping, and in particular relates to a geographic information surveying and mapping system. Background technique [0002] Geographic information system is a specific and very important spatial information system. It is supported by computer hardware and software systems to collect, store, manage, calculate, analyze, A technical system for display and description. A simple latitude and longitude coordinate will only be recognized and understood by the user after it is placed in specific geographic information, represented as a certain location, sign, or orientation. After the user obtains the location information through related technologies , it is also necessary to understand the geographical environment, query and analyze environmental information, so as to provide information support and services for user activities. Geographic information system is a comprehensive discipline,...

Problems solved by technology

[0003] During the use of the surveying instrument, although the support rod at the bottom has a certain stabilizing effect on the body itself, under the influence of a huge external force, such as a collision with a person or a machine, it will also cause the surveying instrument to fall, and the precision measurement at the upper end of the surveying instrument The instrument is exposed, and it will be damaged when it collides with objects; during the use of the surveying instrument, whether it is before or after use, after the surveying instrument is retracted, it needs to be lifted or carried, etc. Overall moving, this kind of moving method is time-consuming, laborious, inconvenient to store and put away, and the efficiency of surveying and mapping is low
