An Efficient Internet Map Tiles Rendering Approach on High Resolution Devices

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.
