Big data system-based Beidou traffic transport data fusion system

Abstract

The invention provides a big data system-based Beidou traffic transport data fusion system. The system comprises a traffic basic geographic information framework data module used for acquiring basic geographic information data and performing preliminary data fusion; a traffic transport network data module used for performing matching fusion on the traffic transport network information and the preliminary fusion data by taking the preliminary fusion data as a reference and combining the traffic transport hub point node information; a traffic real-time big data module used for extracting real-time big data from various traffic transport real-time data; and a data fusion module used for performing position matching and data association on the traffic real-time big data, the traffic transport network data and the traffic basic geographic information framework data through the Beidou traffic geographic information data processing platform so as to realize traffic three-dimensional one-map data fusion. The concept of static data and real-time dynamic data fusion is provided, the effectiveness problem of one graph is solved, and the efficiency of the data of one graph in the aspect of traffic comprehensive transportation network analysis is improved.

Description

technical field [0001] The invention relates to the technical field of data fusion, in particular to a Beidou transportation data fusion system based on a big data system. Background technique [0002] Due to the influence of various factors such as the uncertainty of geographic entities, the limitations of human cognition and expression capabilities, measurement errors, digital acquisition errors, and limitations of expressing geospatial data in computers, spatial information data in the field of transportation will be difficult. Because of different means of acquisition (such as GPS, remote sensing, full field, etc.), data in the business field (such as river maps, sea maps, road maps, railway maps, etc.), different scales, different acquisition times, and different software systems used, etc., resulting in the same Regional geospatial data varies. [0003] At this stage, due to the development of the geographic information industry, the state's management of various basi...
