ABSTRACT

In order to adapt map tiles to high resolution display devices, some internet map providers pre-generate and store more than two sizes of map tiles. However, it is inefficient to download larger high-resolution tiles, and they will occupy a larger storage space on map servers. In this paper, a new efficient internet map tile rendering approach on high resolution devices based on bicubic and Laplacian convolution (BLC) is proposed. Based on BLC, a new efficient internet map tile rendering framework is presented. The experimental results demonstrate that this new approach is effective and efficient for providing a tile map service.

高分辨率设备上的高效 Internet 地图图块渲染方法

摘要

为了使地图块适应高分辨率显示设备，一些互联网地图供应商预先生成并存储两种以上尺寸的地图块。然而，下载较大的高分辨率瓦片效率低下，并且会占用地图服务器上较大的存储空间。在本文中，提出了一种基于双三次和拉普拉斯卷积 (BLC) 的高分辨率设备上新的高效互联网地图瓦片渲染方法。基于BLC，提出了一种新的高效互联网地图瓦片渲染框架。实验结果表明，这种新方法对于提供瓦片地图服务是有效且高效的。
