  This paper presents a concept for a software system called RAIL representing
industrial indoor environments in a dynamic spatial model, aimed at easing
development and provision of location-based services. RAIL integrates data from
different sensor modalities and additional contextual information through a
unified interface. Approaches to environmental modelling from other domains are
reviewed and analyzed for their suitability regarding the requirements for our
target domains; intralogistics and production. Subsequently a novel way of
modelling data representing indoor space, and an architecture for the software
system are proposed.
