Research And Implementation Of Multi-Dimensional Visualization For Soil And Water Conservation With Big Data Based On GIS

China is one of the most serious soil erosion countries in the world.In recent years,with the deepening research of soil and water conservation,the quantity of data continues to increase.With huge data collected,more and more attention has been paid to the information construction of soil and water conservation data.Currently,most schemes focus on the research of front-end data visualization in particular areas with commercial or open source geo-general back-end solutions.These schemes Ignore the characteristics of soil and water conservation data and did not research the visualization architecture deeply,they also lack persistent research on mass water and soil conservation data.Reasonable persistence and visualization of soil and water conservation data can effectively enhance the features of real-time and sharing of the data,and can make the data been showed in a more intuitive and logical way.Visualization can provide a friendly platform with effective statistical results and can take advantages to the further governance of soil and water conservation.This paper analyzes the current methods and achievements of the visualization soil and water conservation at home and abroad in detail.For the shortcomings of the current visualization research,this paper proposes a visualization architecture of water and soil conservation data,combining with the latest Internet visualization schemes and big data persistence schemes.This paper takes the erosion factors of Shanghai as an example to discuss the key technical points of visualizing soil and water conservation data.The main research contents and achievements of this paper are as follows:(1)This paper introduced the current popular Internet visualization library and compared them based on the characteristics of soil and water conservation data.(2)This paper introduced the persistence scheme of soil and water conservation data,and proposed data sharding technology according to the national mass data content.(3)For different types of data content and different visualization purposes,this paper discussed appropriate visualization schemes.(4)Taking Shanghai as an example,the key technologies of each visualization method are researched and applied to the actual system,which can visualize the soil and water conservation data directly and comprehensively.
