A web-based 3D mapping application using WebGL allowing interaction with images, point clouds and models

Nowadays we see a lot of Rich Internet Applications (RIA), but real interactive 3D applications have just started years ago, and it is only in 2011 that a GPU library was integrated directly in the major internet browsers. This opened a new way of creating 3D applications on the web and a new public, as much more users can access them without complicated plugin installations and this is just what 3D web mapping was waiting for. We present our street view application allowing to move through cities from a pedestrian point of view and interact with it in order to create and update precise urban maps enabling accessibility diagnostics, services and applications around mobility. We cared about precision in the data acquisition (images and laser) in order to be able to make accurate 3D measurements for professional usages. The user can show large laser clouds in his web-browser, access information on any points, draw 3D bounding boxes and export selections to databases. He can also make measurements from images, integrate collada models, display OpenData layers, etc. Finally we use projective texture mapping in real time to texture any mesh with our images.
