Obtaining spatial representations of existing buildings for use in simulation is challenging: To begin with, getting permission to access submitted construction plans can take a long time. Then these might only be available in analog form, making it necessary to scan and vectorize them at the regulations office. The resulting representation might still not be adequate for simulation, requiring further extraction of relevant features and enrichment by additional information in order to fit the simulation domain. In our work, we have specifically targeted simulation types that work with schemata (e.g. occupancy, work and egress simulations). Our contribution lies in restructuring the aforementioned workflow so as to (1.) minimize time and effort spent on digitizing and to (2.) automatically derive schemata – sets of boundary polygons which (3.) can be further enriched by attributes. These steps are embedded into a web-based building database which allows uploads and queries per web interface as well as web services. The query interface furthermore includes (4.) the ability to download the schemata both in vector as well as raster form so that they can be used for both discrete and continuousspace approaches. Apart from acting as data provider, the database furthermore (5.) allows for spatial predicate functions which may be used for analysis of a space program.
