There are always more data about cities and urban systems. Different data, different scales. We can divide the available data about cities according to their temporal scale and some of the recent results pertaining to this new science of cities are the following ones, from time scales of order a day to long times such as decades and centuries.

Topology driven methods for complex systems. TOPDRIM a global vision of data. The tale, philosophy, motivations of an ambitious, difficult project. TOPDRIM partners met the day before their review in Brussels. TOPDRIM International School Conference on Topology and Data. A Model for Foraging Ants, Controlled by Spiking Neural Networks and Double Pheromones. Traditional ant systems include mainly a positive reinforcement pheromone.

To provide critical information for its prediction, prevention and control.

The output of the workshop could be a book collecting the DyM-CS roadmap. In order to describe and control these systems there is a need to observe and reconstruct their dynamics and make sense of large amounts of heterogeneous data gathered on various scales. Programme for 25 September 2015.
