Companies and individual developers have recently put serious effort into improving web mapping libraries. A significant front in this development is hardware‐accelerated vector graphics. Owing to those efforts, and the continuously evolving World Wide Web, users can visualize large vector layers, and even animate them. On the other hand, this rapid development cannot be observed with raster data. There are some data abstraction libraries for reading raster files, although web mapping libraries do not use them to offer raster capabilities. Since there are no mature raster management pipelines on the web, this study explores two inherently different techniques for handling raster data. One of them uses the traditional, texture‐based method. The other is a hybrid technique rendering raster layers as vectors, overcoming some limitations of the raster model. While the traditional technique gives a smooth user experience, the hybrid method shows promising results for rendering hexagonal coverages.

在客户端网络地图中使用栅格数据的可能性

公司和个人开发人员最近已在改善Web映射库方面进行了认真的工作。该开发的重要前沿是硬件加速矢量图形。由于这些努力以及不断发展的万维网，用户可以可视化大型矢量层，甚至可以对它们进行动画处理。另一方面，使用栅格数据无法观察到这种快速发展。尽管Web映射库不使用某些数据抽象库来提供光栅功能，但仍有一些数据抽象库可用于读取光栅文件。由于网络上没有成熟的栅格管理管道，因此本研究探索了两种固有的不同技术来处理栅格数据。其中之一使用传统的基于纹理的方法。另一种是将栅格图层渲染为矢量的混合技术，克服了栅格模型的一些限制。尽管传统技术可提供流畅的用户体验，但混合方法在渲染六边形覆盖范围方面显示出令人鼓舞的结果。
