Design And Implementation Of Data Display Platform Based On GIS

The visualization of data show business as the background, the key technology of GIS and the visualization of data, aiming at data needs analysis and display the actual demand of based on GIS data display and visualization analysis. It introduces the whole process of establishing GIS visualization model in the large business data, and display the related Guizhou poverty alleviation business data. Poverty data visualization analysis provides intuitive, three-dimensional and the pyramid data model, in order to meet the requirements of the operational process of query, statistic and analysis and visualization platform for large data.The content introduces WebGIS technology (GEOServer and Openlayer3). After the establishment of hardware system and software system, the content introduces two styles of space data publishment, and introduces the process of vector data publishment and raster data publishment. According to the standard of OGC, it introduces access style and render style of OpenLayer3. Eventually, it introduces the developing process of scatter, thermodynamic, density and anime diagram.For data visualization process and space technology standard, this paper presents three ways of rendering service data. For different data we uses direct rendering, real-time rendering and hybrid rendering request. It introduces the advantages and disadvantages of the three methods and usage scenarios, and gives examples. This content describes the spatial data cache technology, the establishment of buffer space by GWC. It enhances user access speed and concurrency. Given raster pyramid segmentation and segmentation, using the appropriate method to show the pyramid GIS. It describes the entire Big Data Poverty data analysis, statistics, correlation calculation and map display process, In this paper, the CQL spatial data retrieval technology, is introduced to do the relevant spatial data retrieval process, and the corresponding instance. Ultimate It shows the Guizhou Poverty cloud.According to the different visualization needs of Guizhou Poverty business levels, the content introduces the detailed process of Guizhou Poverty cloud big data Visualization show, and according to the corresponding map data present, it shows the form of GIS map, and ultimately provide poverty-Guizhou poverty alleviation Visualization of data analysis and deciding.
