Problems solved by technology

[0005] Usually, the output calculation results of the EFDC model are text files. From the perspective of software development, using text files for query and display is inefficient and poor in data security. From the perspective of software integration, the data structure of the EFDC model is different from that of the GIS system. It is difficult to realize the organic integration of the two

Abstract

The invention provides an EFDC model calculation result visualization method and system. The method comprises: converting an EFDC model calculation grid into GIS data; publishing the EFDC model calculation grid and the background geographic data into a map service through a GIS server; converting a calculation result into a 'time sequence-analog value format' for storage; storing analog values ofall grids at a certain moment in a database; querying an EFDC calculation result, and transmitting the calculation result in the form of two-dimensional data; and loading background geographic data from a GIS server side, rendering the background geographic data to the bottom layer of a map window, establishing the corresponding relation between the water quality simulation value and the calculated grid color, expressing the water quality factor concentration by calculating the depth of the grid color, and dynamically rendering the water quality simulation resultthrough WebGL. By means of themethod, efficient storage, query and transmission of the EFDC calculation result and visual display based on WebGIS are achieved.

Description

technical field [0001] The present disclosure relates to the field of information visualization, and proposes a method and system for visualizing calculation results of an EFDC model. Background technique [0002] The EFDC (The Environmental Fluid Dynamics Code) model is funded by the U.S. Environmental Protection Agency and developed by Hamrick, the Virginia Institute of Oceanography. It is a model that integrates hydrodynamic modules, sediment modules, pollutant transport modules and water quality modules. It can be used for Includes 1D, 2D and 3D numerical simulations of lakes, reservoirs, bays, wetland estuaries and nearshore seas. After nearly 20 years of development and improvement, the model has been widely used in universities, government agencies and environmental consulting companies, and has been successfully used in the research of more than 100 water body regions in the United States and other European countries. It is used in water quality simulation, confluen...
