Overview

Observations View

When the Statistics view provides an high-level overview of the aggregated results the Observations view is about looking into the details of Observations and the raw sensory output.

To help to coupe with amounts of data several controls are provided to help make a specific selection from a given time period and location.

Figure 1.1 provides an annotated screenshot of the Observations view and its various controls. Figure 1.2 shows the raw data spectrum graph of an Observation that has detected oil pollution.

The figures: 1.3, 1.4 and 1.5 demonstrate raw data spectrum graphs of invalid Observations. Frequent invalid observations are a sign of device failure or of an approaching maintenance window.

The annotated circles numbered from 1..11 can be clicked to jump to the details of each presented control.

1. Observer Selection

By default Observations are split per Observer and an Observer is always selected.

2. Date Selection (Calendar)

The calendar allows to select a date which will act as a 24 hour range for selected Observer's Observations.

A green dot icon in the calendar's date field's upper right corner indicates that the selected Observer has Observations on that date.

3. Observation Type Selection

The Observation Type for which data is loaded into the controls below.

4. Auto-update Spectrum, Live Feed Selection

When Auto-update spectrum's checkbox is ticked the spectrum of the last new Observation is loaded automatically into the Raw Spectrum Graph.

When Live feed checkbox is ticked the Selected Hour Plot and 24h Window will start to automatically update themselves as new measurements arrive.

5. Save Spectrum to CSV

Allows to save the raw data spectrum of selected Observation as a CSV file. If no Observation is selected the button is not visible.

6. Raw Spectrum Graph

The raw data spectrum for the selected Observation Type and Observation. The spectrum presented on Figure 1.1 for Oil Pollution shows a regular spectrum pattern when no oil was found.

7. Selected Hour Plot

The hour plot presents an overview of peaks in the selected hour of the 24 hour range corresponding to the date selection in the calendar.

8. Single Observation Selector

The marker for a single selected Observation. The single Observer selection will also trigger a data update for the raw data spectrum graph and for the map, showing the Observation location.

9. Map, Location Visualization

Location visualization and Observation details on the map.

10. 24h Hour Window

The slider window representing the 24 hour range corresponding to a selected date in the calendar.

11. 1h Slide Window

The one hour slide window in the 24 hour range allowing to move back and forth in the 24 hour range.

Figure 1.3 - Observations View - Invalid Observations #fig1-3

The screenshot below shows how invalid Observations are presented on the Selected Hour Plot as separate red line-markers of which one is annotated with the blue circle labeled 1.

Also, notice the differences between the shapes of raw data spectrum in Figure 1.2 - a valid Observation, and in the given Figure 1.3 representing an invalid Observation.
