摘　　要：为了实现对地理位置信息的精准测绘,提出基于GIS技术的复杂地理位置信息抓取系统设计方法。采用基于Telnet协议和SSH协议物联网终端实现对复杂地理位置信息的GIS采样,根据GPS、GLONASS、BDS联合定位识别的方法,实现对地理位置信息的远程遥感测绘和精密定位。结合实时精密单点定位跟踪识别的方法,建立地理位置信息系统的信息收发端,通过空间信号测距误差修正,在GIS信息库中实现对地理位置信息的偏差估计和修正,在精密定位解算中,通过空间信号测距误差估计,实现地理位置信息抓取和自动化捕获。测试表明,采用该方法进行地理位置信息抓取的准确度较高,测距和定位误差较小,提高了地理位置信息的实时捕获和抓取能力。In order to realize accurate mapping of geographic information, a design method of complex geographic information capture system based on GIS technology is proposed. The Internet of Things terminal based on Telnet protocol and SSH protocol is used to realize GIS sampling of complex geographical location information. According to the method of GPS, GLONASS and BDS joint positioning and identification, the remote sensing mapping and precise positioning of geographical location information are realized. Combining with the method of real-time precise single point positioning tracking and identification, the information transceiver of geographical location information system is established, and the spatial signal ranging error is corrected. The deviation estimation and correction of geographic location information are realized in GIS information database. In the precise positioning solution, the geographic location information can be captured and automatically captured through the estimation of spatial signal ranging error. The test shows that this method has higher accuracy in capturing geographic location information, smaller ranging and positioning errors, and improves the real-time capturing and capturing ability of geographic location information.
