Abstract

The invention relates to an assistant positioning technique facing industrial application and particularly relates to a terminal processing method for a mobile GIS (Geographic Information System) assistant positioning system. The terminal processing method is characterized by comprising the steps of 1) acquiring position coordinates of a GPS (Global Positioning System); 2) selecting a reference datum point; 3) positioning and correcting to obtain a projection parameter; 4) collecting and correcting the actual positioning data. According to the terminal processing method provided by the invention, an observation point is accurately positioned by a user through GPS positioning of a mobile terminal and a mobile GIS module on the mobile terminal, so that the measurement accuracy and the scope as well as the adaptability of the measured application are improved.

Description

technical field [0001] The invention relates to an auxiliary positioning technology oriented to industry applications, in particular to a terminal processing method of a mobile GIS auxiliary positioning system. Background technique [0002] Since the 21st century, the application of mobile positioning technology has become more and more extensive. Specialized mobile positioning system [2] can be used to locate people, events and objects to meet the positioning needs of mobile law enforcement, mobile office, transportation, logistics, tourism, land and resources investigation and other industries. There are two positioning technologies, one is GPS-based positioning, and the other is base station positioning based on the mobile operating network. The GPS-based positioning method uses the GPS positioning module on the mobile phone to send its own position signal to the positioning background to realize the positioning of the mobile phone. Base station positioning is to use th...
