The low surface brightness Universe (µr ~ 28.5-29 mag arcsec-2) remains almost unexplored. Its analysis is a technical challenge from the observational point of view but also requires a very sophisticated data treatment. The incoming deep and wide surveys as the LSST or Euclid, will allow us to explore low surface brightness objects such as stellar haloes of galaxies, intra-cluster light or Galactic cirrus. Thus, it is necessary to develop new techniques and software procedures that improve the reduction of huge amounts of astronomical images and prevent the removal of large and diffuse astrophysical structures.

\r\n\r\nWith the current emergence of Terabyte(TB)-scale astronomical and Earth observation systems, the traditional approach to basic functions such as data searching, analytics or visualization are becoming increasingly difficult to handle. Simple database queries can result now in data subsets so large that they are incomprehensible, slow (or even impossible) to handle, and impossible to visualize with commodity visualization tools. Astronomy and remote sensing complement each other, as they are on the quest for new Big Data interpretation capabilities: both disciplines have peculiar data, typical data processing and analysis chains, and specific models to be fed with data. However, both disciplines lack the capabilities for easily accessible semantics-oriented browsing (usage of higher level descriptive expressions) in large data archives. Therefore, joint efforts to design and develop innovative Big Data tools should help users in many different fields and set new standards for many communities. This has identified several broad challenges to this line of reasoning that need multidisciplinary approach through international networking of experts and professionals. These challenges are then channelled into Action Objectives:
\r\n– Challenge A: Digital curation and data access
\r\n– Challenge B: New frontiers in visualisation
\r\n– Challenge C: Adaptation to new high performance computing (HPC) technologies
\r\n– Challenge D: New generation of scientists in the age of interdisciplinarity
