Research Of Vector-Tile Electronic Map Mapping Template Based On Mapbox

Under the background of the rapid development of computer technology,network technology,and digital map mapping technology,the network map mapping has gradually become the mainstream mapping model.With the rise of geolocation services and the continuous development of data collection technologies,the network map mapping service based on the pyramid cache model cannot meet the needs for visualization styles,map interactions,and spatial analysis.The map visualization faces great challenges,such as the quantification of map data,the popularization user groups,diversification of map styles and so on.In addition,traditional network map mapping not only requires cartographers to have higher map literacy and aesthetic qualities,but also needs programming ability.And there exsist problems such as heavy work and low cartographic efficiency in the mapping process.Therefore,the rapid,efficient and intelligent mapping of geospatial data in the network environment has become a research hotspot.The above problem is solved by Vector-tile electronic map,which has many advantages such as lightweight data,high-definition display,rapid response,high efficiency update,multiple sources,strong interaction,and no plug-in to implement two-dimensional integration..In the field of vector map service provision,Mapbox perfectly combines the Internet,cloud computing,mobile computing and traditional map cartographic design,it’s a creators or contributors of open source libraries,application programs,and industry specifications.This paper has carried on the preliminary exploration to the mapping template of vector-tile electronic map,and designed the vector-tile electronic map service program based on Mapbox,by using basic geographical data of deqing county,Zhejiang Province.The service program provides the new technical method for the high-efficient network transmission of spatial data and fast rendering display.A process design of vector-tile electronic map mapping template is described from the multi-scale data organization,the cartographic expression and spatial conflict in map elements expression in detail.Beside,five different styles of scripted electronic maps are designed based on Mapbox GL style configuration.In order to simplify the mapping operation,the script drawing information is packaged into the drawing rules to realize templated drawing,by combineding with map design expert knowledge and software design.On the basis of above,the application framework of vector-tile electronic map mapping based on Mapbox is constructed,which provide users with a variety of efficient and convenient mapping services.
