HTML5 is being developed as the next major revision of HTML (Hypertext Markup Language), the core markup language of the World Wide Web. It aims at reducing the need for proprietary, plug-in-based rich Internet application (RIA) technologies such as Adobe Flash. The canvas element is part of HTML5 and is used to draw graphics using scripting (e.g., JavaScript). This paper introduces Cartagen, an open-source, vector-based, client-side framework for rendering plug-in-free, offline-capable, interactive maps in native HTML5 on a wide range of Web browsers and mobile phones. Cartagen was developed at MIT Media Lab's Design Ecology group. Potential applications of the technology as an enabler for participatory online mapping include mapping real-time air pollution, citizen reporting, and disaster response, among many other possibilities.
HTML5 正在被开发为下一代 HTML（超文本标记语言）的主要修订版，它是万维网的核心标记语言。它旨在减少对专有、基于插件的富互联网应用程序（RIA）技术的需求，例如 Adobe Flash。画布元素是 HTML5 的一部分，用于使用脚本（例如 JavaScript）绘制图形。本文介绍了 Cartagen，这是一个开源的、基于矢量的、客户端框架，用于在各种 Web 浏览器和移动电话上以原生 HTML5 呈现无需插件、离线支持、交互式地图。Cartagen 是由麻省理工学院媒体实验室的设计生态学小组开发的。该技术作为参与式在线地图绘制的推动者的潜在应用包括实时空气污染、公民报告和灾害响应等。
