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,...
