The winter of 2018-2019 was quite cold and snowy, with the most snow in the North West, New South Wales, Queensland and South Australia.
But it was not all bad news for the snow maps.
It turned out the snow was actually quite good for the map because it was mostly from rainfall.
In 2018-19, the total amount of rain was around 3.5 million millimetres, which was just over half of the amount recorded in previous years.
Snow on snow maps was also very useful because the snow covered roads and bridges, so it could help to keep people safe in the city.
The snow maps had been used by government departments to collect and analyse the snowfall, and the data was used to help the Australian Government formulate road and rail projects, and to develop snow mapping software.
The data was then used by local governments and other organisations to plan road and train routes.
Snow maps can also be used to show which roads have fallen into bad condition, so roads can be built in a better state, and when roads are resurfaced.
The maps were also used by the state government to collect data on how many people were walking in the cities, and how many were cycling or walking.
But the snow and rain data also meant that it was possible to calculate the amount of snow that was left in a city, and even to compare snowfall on different maps.
