We propose a specification of moving objects query language over GML for LBS extended by XQuery. Conventional query languages over GML have been focused on the development of interoperable Web GIS, the enrichment of existing XML language with spatial operators, and etc. However, these studies are not suitable for direct query of GML repositories by the lack of alignment with XQuery. Also, there is no consideration on the query language over GML to support moving objects query for LBS. Therefore, we show the data model, the algebra, the set of operators and representative query examples underlying the proposed moving objects query language to specify moving objects features. Finally, we apply the proposed query language to tornado monitoring system to show that this language comes into use in various LBS applications effectively.
