Wireless sensor and actuator networks (WSAN) are a combination of embedded, wireless and positioning technologies. Existing geospatial standards used in location-aware systems can be applied in building these networks, but they present challenges due to the characters of the geosensor networks. In this paper, we present a study of geospatial standards related to location-aware system platform for improving its interoperability. The location-aware system platform used here is Locawe. Locawe has been developed in CENTRIA and tested with wireless sensor and actuator network technologies in various industrial pilots including precision agriculture. This paper includes an experimental part, where we focus on geospatial standards in WSAN. In this field, geospatial standards are still under specification. Our first results show that geospatial standards can be applied also in WSAN, with certain limitations. These limitations are mainly related to low-rate data transmission and limited computing resources. We propose also further directions in standardization, which would be needed for geosensor networks and wireless applications for machines and systems.
