The map consists of the underlying basemap, the data on the map, as well as a number of other features.
Basemaps
There are 2 options available for the underlying map.
Navigation Map
This is the most common basemap, and is used for displaying single points (pins) on a map)
Grey Map
This is used when there is more complex information such as shapes or lines. It is also used when there are more than 3 colours of pins.
Map Locations
Locations can be represented as points, lines or polygons. The most common location type is a point or pin.
Pins
Pins represent a single location on the map.
It is recommended that the same colour & icon are used for all pins for accessibility as it is hard to distinguish colours & icons.
Clustering
When the map is zoomed out, the pins are clustered to make the map easier to view and reduce load times
Lines
Lines are used for linear shapes such as road segments.
When using many colours, line weights and dashes should be considered as well.
Polygons
Polygons are used for shapes such as a ward or neighbourhood map.
