Interoperability between Domains - Bridging Industrial Control Systems and Geographic Information Systems

b COPA-DATA GmbH, Karolingerstrasse 7B, A-5020 Salzburg, AUSTRIA ABSTRACT 1 : This paper presents the conceptual design and the related implementation of a bidirectional domain inter- connection bridging Supervisory Control and Data Acquisition (SCADA) systems and Geographic Infor- mation (GI) systems. Due to the numerous common interests and the fact that both realms, SCADA and GIS, have their own central information, namely time-based sensor data and geographical position, a connection between these domains is a benefit for both of them. Therefore, the authors designed and implemented a bidirectional software connector by the use of implementations of the two standards OPC UA and OCG SOS. The presently linked information from a SCADA system can be utilized and further augmented by a GIS, which can then readdress its outcomes to the former and vice versa. The proposed adapter and its components have been validated in a real-world scenario. The data from three different experimental buildings were visualized and exchanged between a SCADA/HMI-System and a GIS using the developed software prototype.
