Layer settings

To change a layer, open it from the Layers list and select Settings. The settings are grouped into Layer, Time Period, Boundary, Filters and Style. Only the groups the chosen source uses are shown.

After changing the type, source, time period, boundary or filters, select Refresh to load the layer again. See Refresh a layer.

Layer

A layer’s settings: Layer, Time Period, Boundary, Filters and Style

Label: a name for the layer, up to 50 characters. It’s shown on the layer’s card and in the saved retrospectives list.
Type: how the layer is drawn. See Layer types. Changing the type clears the source, because each type offers different sources.
Source: what data the layer shows. See Sources.

Layer types

Type	What it draws
Shape	Each item where it is: a point for a stop, a line for a trip, an outline for a location.
Bubble	Points grouped into bubbles, each showing how many items it holds. Select a bubble to zoom in until it splits. Close in, every item is shown on its own.
Heat	A heat map showing where items are most concentrated. Zoom right in and it turns into individual points that you can hover over and select.
Area	Areas of one type, such as wards or beats, shaded by their total for the chosen measure. Busier areas are shaded further along the layer’s colours.
File	The points, lines and shapes in a GeoJSON or KML file you upload.

Area layers

An area layer listing wards by their total, with the map shaded by area

Area layers have two more settings:

Area Type: which areas to total up, such as wards or beats. Select the Exclude untouched areas button at the end of the field to leave out areas with nothing in them. New
Group By: optionally, combine the areas into a larger kind of group, such as sectors, and total each group instead.

Sources

Changed

The sources on offer depend on the layer’s type. Person sources are available depending on your organisation’s set-up.

Vehicles

Source	Types	What it shows
Vehicle Stops	Shape, Bubble, Heat	Where vehicles stopped, and for how long.
Vehicle Idles	Shape, Bubble, Heat	Where vehicles idled, with their driver.
Vehicle Trips	Shape	Journeys, with driver, distance, top speed and use of warning equipment.
Vehicle Location Visits	Shape	Vehicles’ paths through IR3 locations, with the location, time spent and distance.
Vehicle Custom Boundary Visits	Shape	Vehicles’ visits to the layer’s boundary, and whether they parked there. Needs a boundary.
Vehicle Speed Infractions	Shape	Stretches driven over a speed rule, with the rules broken.
Accelerometer Events	Shape	Harsh driving events, with their forces.
Vehicle Objective Attendances New	Shape	Vehicles attending objectives, and whether each attendance met the objective.
Vehicle Polls	Heat	Every reported vehicle position, with speed, ignition and warning equipment. Needs a boundary.

People

Source	Types	What it shows
Person Trails	Shape	Where people went, with duration.
Person Location Visits	Shape	People’s paths through IR3 locations, with the location, time spent and distance.
Person Custom Boundary Visits	Shape	People’s visits to the layer’s boundary. Needs a boundary.
Person Objective Attendances New	Shape	People attending objectives, and whether each attendance met the objective.
Person Polls	Heat	Every reported radio position. Needs a boundary.

Incidents, locations, objectives and files

Source	Types	What it shows
Incidents	Shape, Bubble, Heat	Incidents open during the period, with grade, type, response and times.
Locations	Shape	IR3 locations in use during the period, drawn by their boundaries.
Objectives New	Shape	Objectives running during the period, drawn by their boundaries.
GeoJSON	File	The features in a GeoJSON file.
KML	File	The features in a KML file.

Area measures

Area layers total up one of these for each area:

Measure	What it totals
Vehicle Stop Count	Number of vehicle stops.
Vehicle Idle Count	Number of vehicle idles.
Vehicle Visit Count	Number of vehicle visits.
Vehicle Time	Time vehicles spent in the area.
Person Visit Count	Number of person visits.
Person Time	Time people spent in the area.
Incident Count	Number of incidents.

Time Period

Choose the Type of period:

Absolute: a fixed Start and End. The end must be after the start.
Relative: a period counted back from now, such as the previous 7 days.
1. Enter a number in Duration.
2. Choose days, weeks or months at the end of the field.
3. Select the calendar button to switch between Excluding today and Including today.
  - Excluding today: the period ends at the start of the current day, week or month. For example, the previous 7 days are the 7 whole days before today.
  - Including today: the period runs to the end of the current day, week or month, so it includes the current one.
  The button says “today” whichever unit you choose.

A relative period is worked out again every time the layer loads, so a saved retrospective always shows the latest period.

A layer shows everything that overlaps its period. Trips or visits may start before it or end after it. Incidents, locations and objectives that were still open or running count too.

Boundary

Changed

A custom boundary: its outline on the map, with Draw, Download and Upload under the Boundary type

A boundary limits the layer to items that touch an area. On area layers, it also limits which areas are shown. Polls and custom boundary visits must have one.

Choose its Type, or clear the field for no boundary:

Location: choose a Subtype, then the location’s Name.
Objective: choose the objective’s Name.
Custom: draw or upload your own:
- Draw (green) starts drawing a shape on the map. While you’re drawing, the button turns red as Cancel. Once you’ve drawn a boundary, it turns orange as Redraw.
- Download saves the boundary as a GeoJSON file, so you can reuse it or share it. New
- Upload loads a boundary from a GeoJSON file (.geojson or .json, up to 5 MB). The file must contain a polygon. New

The boundary is drawn on the map as a dotted line in the layer’s colour.

Filters

Changed

Filters narrow a layer down to particular vehicles, people, locations, objectives or incidents, or to events with particular details.

Select Add filter (+) at the top right of Filters.
Choose a field. The menu is grouped by what each field describes, for example Vehicle, Driver, Person, Location, Objective or Incident. The source’s own event details come last, headed with the kind of item, such as Vehicle Trip.
Set the condition and the value.
Select Refresh to load the layer with the filter.

To remove a filter, select the ✕ beside it.

Which fields are on offer depends on the source and on your organisation’s set-up.

Conditions for fields with a list of values

Select the icon at the start of the field to change the condition:

Includes: items with any of the values you pick.
Excludes: items without any of the values you pick.
Any New: items where the field has a value.
None New: items where the field is empty.

Conditions for numbers

Choose =, ≠, >, ≥, < or ≤, then enter the number. Durations and similar fields have a unit you can change at the end of the field.

Style

Changed

Changes to the style apply straight away, without a refresh.

Colour or Colours: select a colour to change it. Use the plus and minus buttons to add or remove colours.
- Shape, Bubble and File layers use one colour.
- Heat layers use up to five, running from sparse to dense. They start as blue, green, yellow, orange and red.
- Area layers use up to five, running from the quietest areas to the busiest.
Opacity New: how solid filled shapes are. Shape and File layers start at 30%, and Area layers at 80%. Lines and points stay solid.
Fade lower values New (Area layers): makes quieter areas more transparent. It’s on to begin with for one-colour area layers.
Cluster distance (Bubble layers): from 4 to 10. Higher values gather points from further apart into each bubble.
Radius (Heat layers): from 1 to 20. How far each point spreads.
Intensity Changed (Heat layers): from 1 to 20. How strongly points add up.

File layers

File layers show the points, lines and shapes from a file of your own. For example, you could load a file exported from another mapping tool.

Set the layer’s Type to File, and its Source to GeoJSON or KML.
Select Upload and choose the file. It can be up to 5 MB. Once loaded, the file’s name and number of features are shown under the button. Replace loads a different file.
Optionally, choose a Title Field and a Subtitle Field. These are the file’s own properties used to name each item in the list and its popups.

The file is saved with the retrospective. File layers have no time period, boundary or filters.
