Polymaps is a JavaScript library for generating “slippy” maps in the style of Google Maps, Modest Maps, CloudMade and OpenLayers. Most mapping libraries focus on 256×256-pixel image tiles, with only limited support for dynamic overlays such as county boundaries and point clouds. These libraries assume that data needed to produce the desired overlay can be loaded into memory all-at-once, making it difficult to visualize large datasets. Furthermore, while image tiles automatically adjust in resolution as the map zooms in or out, the overlay resolution remains constant; this greatly limits multi-scale exploration of data, as the resolution must be fixed either for macro- (e.g., state-level) or micro- (e.g., block-level) observation. The goal of Polymaps is to better support rich, large-scale data overlays on interactive maps by extending the tile metaphor to vector graphics: in addition to standard image tiles, Polymaps supports vector tiles that are rendered with SVG. The vector geometry is loaded as GeoJSON via asynchronous XMLHttpRequest; Point geometry objects are rendered as SVG circle elements, Polygons as paths, and so on. By loading geometry at known tile boundaries, requests can be issued efficiently on-demand by the client, and responses trivially cached on the server. When the user zooms in, geometry can be seamlessly refined to show greater detail, while on zoom out, geometry can be simplified to improve performance.

Hello, from wiki : Detail : Company / developer Mozilla Corporation Programmed in HTML, CSS, Javascript,[1] C++ Supported platforms ARM Kernel type Monolithic (Linux kernel) Default user interface Graphical Official website http://www.mozilla.org/firefoxos/ Mozilla has finally launched an operating system for smartphones, one whose ascendancy will probably be a slow burn, but could also mark big changes in the way people interact with mobile devices — by ditching a closed “ecosystem.” Firefox OS for mobile phones is not a walled garden like Apple‘s iOs, Windows Phone or (to an extent) Android. It is based on the open web, which means interacting with many of its HTML5-based apps will be like visiting websites through a browser, opening temporarily as apps, and closing. The phone, in essence, is a browser. Mozilla says Firefox phones will be the world’s first “open web devices.” source : wiki and forbes sites
