Visual Query Systems (VQS) are becoming a very attractive field of research, especially for advanced database systems such as spatial and temporal ones. However, most of the visual query proposals support either spatial or temporal data but not both. This paper presents a new VQS which supports querying spatio-temporal data. The main idea is to provide a web-based, user-friendly, and visual environment for querying generic spatio-temporal databases. Therefore end users do not need to worry about neither data schemas nor query language syntax. The proposed VQS is based on well-established standards such as SQL and OpenGIS, and it is flexible to be used in many database systems with support for spatial data.
