Recent technological advances in spatiotemporal observation gathering have prompted new applications which handle spatiotemporal information. Such information treatment in database management systems (DBMS) has been a growing research agenda in geographic information science. Existing DBMS have been extended to deal with spatial data, complying with the Simple Feature Access (SFA) specification. This compliance has assured a fair degree of spatial data interoperability. This paper presents a summary of an ongoing work whose objective is to extend the SFA database schema to deal with spatiotemporal observations. The proposed schema also addresses three data types, moving object, geosensor time series and coverage, which are built on spatiotemporal observations.
