=== Observations View
When the [wiki:WikiStart#stats-view 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.

[#fig1-1 Figure 1.1] provides an annotated screenshot of the //Observations//
view and its various controls.

==== 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 24 hour range for given
Observer Observations.

==== 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.

==== 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 [#fig1-1 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.
