Development And Implementation Of Vector Tile Web Mapping System Based On Mapbox

With the continuous development of the information industry,the application of GIS has become more and more extensive.Electronic maps have been constantly put forward new requirements as the basis of GIS.People are no longer satisfied with the simple navigation of the map.It is proposed for the timeliness and user experience of the map.Higher requirements.Therefore,an important content is:seeking new ways to improve the efficiency of map data transmission,improve the rendering effect of maps,simplify the complexity of cartography,change the loading data format and cartographic rendering methods,and solve the problems that arise during data production and map mapping.Related questions.The paper summarizes the development background and significance of the vector map Web mapping system based on Mapbox,discusses the problems of slow loading of map data,timeliness of map data,map rendering and map Web mapping,analyzes WebGIS,vector tiles,map rendering Based on the knowledge and techniques related to technology and Web mapping technology research,the work has been done on shapefile to MVT data conversion methods,slice intersection fusion processing,complex polygon processing,Web mapping,creating fonts,and creating icons.Cartographic system from data to maps.Finally,based on the Mapbox platform,using Java language and IntelliJ IDEA integrated development environment,developed a Web mapping system,the main realization of the data format conversion,map rendering,style file generation,font file generation,icon file generation,Web-side mapping and other functions.The Mapbox-based vector map Web mapping system implemented in this thesis is designed for the problems of the slow updating of the data and the complicated maps of the current Tianma.Zhejiang.The system slices slices in real time to generate vector tiles.With Google coding,the data volume is small.When the data is loaded,the bandwidth is small.This prevents the data from loading and affecting the user experience.The system renders the data on the client side,and can modify the drawing style on the client through the style file,which improves the efficiency of drawing.The system changed the original database modification,mapping,slicing,generating bitmaps to publishing service applications,the process is cumbersome,long update cycle and other defects,to achieve a change in the underlying data,only need to modify the basic data of the database,the system will Real-time slicing,and can quickly adjust the map style function according to user needs.The system solves the problems of long time for basic geographic data changing to map services,data lagging,and other issues,so that the data can be quickly applied to serve people's production and life.
