一种基于高分影像的矢栅融合地图瓦片构建方法
Construction Method of Vector and Raster Fusion Map Tile Based on High-resolution Images
摘要
Abstract
For map application scenarios where high-resolution remote sensing images were dominant and vector data was used less but indis-pensable,we proposed a new method to fuse vector and raster data and construct map tiles.Map services based on tile are currently the main-stream mode of WebGIS.Different tile construction schemes will affect the rendering and caching efficiency of map.Existing solutions are gener-ally suitable for scenarios that require processing large amounts of vector and raster data,requiring the release of multiple tiles,which increases the complexity of construction and release.The proposed method designs a color scheme based on the characteristics of terrain features,colors the vector element data,replaces the corresponding pixel values in the remote sensing imagery with the corresponding grid units,and generates the raster data and performs slicing and publishing.The experimental results show that this method can effectively construct map tiles that fusing a small amount of vector element and remote sensing image,ensuring seamless integration of vector and raster data at different zoom levels,and providing clear and intuitive display effects.关键词
