Around the 2D plan: improving the visualisation
and manipulation of digital information

The AP2 project aimed to explore ways of visualising and manipulating digital information related to a plan. Plans are two-dimensional representations that constitute a shared knowledge base in many industries, often with more specific information aggregated upon them. In most use cases, this information is now digital, and sometimes even three-dimensional.

One result of this transformation is the emergence of a number of relationships to be studied, including the relationships between 2D plans and 3D data. Another issue is the need to cater for users from varied backgrounds. AP2 addresses these problems by considering the need for smooth interaction with a collaborative environment that incorporates more and more digital data and connected devices.

The project studies this theme from the viewpoint of two use cases: the review of architectural projects and the public consultation of 2D and 3D data relating to a territory.
