    • Aggregation languages for moving object and places of interest 

      Gómez, Leticia Irene; Kuijpers, Bart; Vaisman, Alejandro Ariel (2008)
      "We address aggregate queries over GIS data and moving object data, where non-spatial information is stored in a data warehouse. We propose a formal data model and query language to express complex aggregate queries. Next, ...
    • Analytical queries on semantic trajectories using graph databases 

      Gómez, Leticia Irene; Kuijpers, Bart; Vaisman, Alejandro Ariel (2019)
      "This article studies the analysis of moving object data collected by location-aware devices, such as GPS, using graph databases. Such raw trajectories can be transformed into so-called semantic trajectories, which are ...
    • Categorical sequential pattern mining in a spatio-temporal environment 

      Gómez, Leticia Irene (c2009)
      "En esta tesis argumentamos que la información de trayectorias también puede ser integrada con datos GIS y OLAP, generando un marco poderoso de análisis".
    • Piet: a GIS-OLAP implementation 

      Vaisman, Alejandro Ariel; Gómez, Leticia Irene; Kuijpers, Bart; Escribano, Ariel (2007)
      "Data aggregation in Geographic Information Systems (GIS) is a desirable feature, although only marginally present in commercial systems, which also fail to provide integration between GIS and OLAP (On Line Analytical ...
    • Temporal SOLAP: query language, implementation, and a use case 

      Bisceglia, Pablo; Gómez, Leticia Irene; Vaisman, Alejandro Ariel (2012)
      "The integration of Geographic Information Systems (GIS) and On-Line Analytical Processing (OLAP), denoted SOLAP, is aimed at exploring and analyzing spatial data. In real-world SOLAP applications, spatial and non-spatial ...
