Design And Implementation Of Geospatial Big Data Visualization System For Dynamic Monitoring Of Soil And Water Conservation Based On Webgis

In recent years,our country has paid great attention to the situation of soil and water loss,and has always treated soil and water loss as an important ecological problem in our country.In order to solve the harm brought by water and soil loss to the economy and society,the state has been strengthening the control of water and soil loss,strengthening supervision methods,and constructing a scientific and efficient dynamic monitoring support system for water and soil conservation.The dynamic monitoring system of soil and water conservation uses soil erosion models to perform large-scale geographical big data calculations,obtains and visualizes the dynamic monitoring results of soil and water conservation.The monitoring results need to be visualized for data presentation and interaction,which is convenient for exploration and analysis,and professionals can mine the meaning of the data.However,the challenges faced by the current visualization work are also very severe,including problems such as huge data scale,difficulty in ensuring data update consistency,untimely data release,and poor user interaction experience.Based on Webgis technology,this paper provides Web-side visual interaction and sharing for large-scale soil and water conservation dynamic monitoring geographic big data.In order to solve the above problems,this paper formulates and implements the entire visualization design scheme from five aspects:data source storage scheme,automatic publishing mechanism,rapid visualization strategy,and Web-side rendering.Realize rapid visualization with the help of WMTS service of GeoServer map publishing service,and provide an automatic publishing mechanism for it,support user-defined publishing schemes to enhance publishing capabilities,and ensure the consistency of published data and tile cache data updates,from data publishing to data Loaded into the Webgis system for data visualization interaction.The test results in the laboratory test environment show that the scheme proposed in this paper can effectively solve the problems faced by the visualization work of the current soil and water conservation dynamic monitoring system.The research contribution of this paper is to provide a data visualization scheme for soil and water conservation dynamic monitoring based on Webgis technology,and provide automatic release mechanism and rapid visualization strategy for it.At the same time,it also pointed out the limitations and deficiencies of this study,which need to be further improved and perfected.Through the research of this paper,the visualization and interaction of dynamic monitoring data of water and soil conservation can be better supported,the utilization value of data can be improved,and scientific basis and technical support can be provided for soil and water conservation work.
