Abstract

The invention relates to an electronic mapping implementation method based on a handheld terminal. The method is characterized by comprising the following steps: S01, encrypting and packing map sheet data related to a project according to the name of the project and a working area of field quality inspection, and introducing the data into the handheld terminal; S02, retrieving the map sheet data of the current position of quality control personnel via the positioning function of the handheld terminal; S03, selecting a real point from the map sheet data via a set buffer value, reading the coordinate values of the real point transmitted by data reading and acquiring equipment for displaying in a laminated manner, calculating an accuracy error value, displaying a check point with different colors according to the accuracy requirement of a specification, checking whether sheet surface ground feature data are lost or wrong, and sketching an error position. By adopting the method, the quality reliability of data results can be enhanced, the overall mapping level is raised, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a method for implementing electronic surveying and mapping based on a handheld terminal. Background technique [0002] With the continuous improvement of social productivity, the level of electronic science and technology has also been continuously improved. It constantly impacts the traditional crafts in various disciplines of society, including surveying and mapping production technology. Traditional surveying and mapping production technology can only collect data through on-site surveying and mapping or mapping, and then return to the office for corresponding data processing through computers. Moreover, it is necessary to print a large number of drawings and materials to mark and modify errors during field surveying and quality inspection, which directly leads to an increase in production costs, and the ensuing waste of resources and environmental pollution are ...
