Abstract

The invention discloses a GPS based path diagram drafting method and system. Measuring data of a GPS plotting device is received, the measuring data is parsed according to format information corresponding to identification information of the GPS plotting device, and a temporary path diagram is drafted according to the parsed measuring data; according to a real path, error points in the temporary path diagram are modified, and the path direction in the temporary path diagram is adjusted; and according to the temporary path diagram and the adjusted path direction, an effective path diagram is drafted. According to technical schemes of the invention, the measuring data can be parsed by selecting the format information corresponding to the identification information of the GPS plotting device instead of being processed in a unified format, data errors can be reduced, the drafting accuracy of the path diagram is improved, work is less tedious, and the working efficiency is improved.

Description

technical field

[0001] The present application relates to the technical field of surveying and mapping, and more particularly relates to a GPS-based route drawing method and system. Background technique

[0002] With the rapid development of economic construction and more and more road construction projects, the speed and accuracy of road measurement are particularly important. As a high-tech global satellite positioning technology, GPS has real-time, fast, all-weather, high-precision, high- Notable features such as efficiency and simple operation have been widely used in many industries such as power grids, construction, and transportation.

[0003] At present, GPS-based real-time dynamic positioning technology is more and more applied to surveying and mapping technologies such as route map drawing. The existing route map drawing method mainly uses the designer to extract the correct geographical coordinate information according to the measurement data of the corresponding...
