Isopleths

Isopleths are curved lines of equal values. This photo shows the annual mean snowfall in Canada and the United States. This can be useful in various ways, one being practical information for a family searching for a place to settle down in either of these two countries. If it is important for their children to grow up seeing snow fall each year, they might want to consider living in the northern parts of the map, certainly not Florida or most of Georgia.
