Figure 1. Overview of the Dwell-time page UI

Going clockwise, the dwell-time page has the following UI elements

  • Select type: allows you to switch between showing the average dwell time (bar charts) or individual dwell times (table).

  • One/Two time periods toggle: toggle between analyzing a single time period, or doing side-by-side comparisons of 2 different periods. Two periods is only supported for average dwell time analysis.

  • Time period selector: choose which time period to use. You can select one of the predefined ones, or create a custom one.

  • Timezone selector: select in which timezone you want to see the results displayed. This is also the timezone in which the time filters you define are interpreted.

  • Areas of interest selector: choose the areas to include in the analysis. Each of the selected areas will be used to compute the average dwell time for, or to detect assets that enter and exit the area.

    The areas you can choose from are obtained from the areas of interest included in your project, as well as the areas you have drawn on the spatial map of the visual analytics page using the map controllers.

  • Attribute and time filters: you can filter the records that are used to calculate the analysis. For example, it allows to only include the "Cargo vessels" and "Fishing boats" instead of all vessels when calculating dwell time.

    You can filter on properties in your data, as well as some additional time filtering (days of week, hours of day, months of year).

    The UI to create these filters is the same as on the visual analytics page, explained here and here.

  • Widget pop-up menu: shows a pop-up menu with additional options:

    • Export the data behind the analysis to a .csv file.

      The format of the exported csv data

      In case the average dwell time is selected, the data saved to the .csv file is in seconds with a row for each selected area.

    • Add the dwell time widget (bar chart or table) to the dashboard.

  • Chart/table: the computed chart(s) or table
