Feature Layers Section
This is a list of feature layers that are available for the current map extents and zoom level.
Additional feature layers are usually visible by zoom in and feature layers automatically hide
as you zoom out.
The available feature layers are controlled by the organisation config and can include incident feeds,
traffic feeds, traffic/weather cameras, river/weather observations, road closures, fire stations and more..
Overlays Section
The list of available grid layers will depend on the current map extents. Click a
grid overlay to show/hide it on the map.
Selecting a grid overlay, will automatically turn of any other grid layer that are
currently turned on. It is not possible to have more than one grid layer turned on
at a time.
UTM Grid Overlay
This UTM grid is used by most emergency services for ground operations, since it is an
easy grid to work with, since all grid squares are in metres (easting/northing). This
grid is the same grid used for topographic maps in Australia and USA.
NZTM Grid Overlay
The NZTM grid is used by emergency services in New Zealand as a preferred grid
instead of using UTM. This is the same grid that is used by the NZ Topo250 and
NZ Topo25 base layrers. It is available to all users when using maps for NZ.
Lat/Lng Grid Overlay
The Latitude/Longitude grid is used by emergency services, mostly for aircraft
operations. It is better suited for working over long distances due to the
curvature of the earth.
Overlay Layers
List of available overlays layers will depend on the current zoom level. Click a overlay to
show/hide it on the map. Selecting an overlay, will automatically turn of any other overlays
that are currently turned on. It is not possible to have more than one overlay layer turned
on at a time.
Ground Tracks
Displays recent location tracks heatmap for personnel and appliances. This is useful for
seeing how ground personnel are accessing an incident (such as what trails are in use, how
are appliances getting around a fences at an incident). There is significant delay for the
ground tracks overlay.
Aircraft Tracks Overlay
Displays recent location tracks heatmap for aircraft. This is useful as a summary of previous
aircraft movements at an incident. There is significant delay for the aircraft tracks layer.
Hotspots Overlay
The hotspots overlay consists of satellite detected hotspots from MODIS, VIIRS and Himawari-8
satellite. These satellites provide a snapshot of large fire activity when the satellite passes
overhead. The color of the dots is determined by age, recent fire activity is displays as red,
then orange, yellow and black. Older hotspot activity will fade away after 7 days.
Feature Scale
This slider determines the size of the map features on the screen. You can use this slider
to make the map features larger, which is useful when using the FireMapper Portal on large
screens or when conducting incident briefings.
