Abstract

The invention discloses a massive multi-source data fusion visualization method for urban surface monitoring, which comprises the steps of S1, data acquisition: acquiring geographic information data and sensor data, and generating a three-dimensional terrain model; wherein the geographic information data comprises geographic position, morphology information, texture information and structure information; S2, information transmission: transmitting the geographic information data acquired in the step S1 to a cloud server; and S3, fusion processing: performing multi-source data fusion processingat a cloud server side, and performing data fusion processing and the like on the geographic information data, the sensor data and the general map data; according to the method, the texture information and the like of each entity can be accurately described, the universality is high, the data information of each entity can be comprehensively described, and the visualization degree is high.

Description

technical field [0001] The invention relates to the technical field of geographic information systems, and more specifically, to a method for fusion and visualization of massive multi-source data for urban surface monitoring. Background technique [0002] The combination of Geographic Information System (GIS) and Building Information Modeling (BIM) is an important technical path for building a smart city. Due to the large amount of data and complex structure of BIM data, there are problems such as low degree of visualization and poor versatility when combined with GIS information. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a fusion visualization method for mass multi-source data of urban surface monitoring, which can accurately describe the texture information of each entity, etc., has strong versatility, and can comprehensively describe the data of each entity Information, high deg...
