Mapping with Purpose

In “Mapping with Purpose,” Heather Smith of Esri uses blueberry crops in Canada to make a very good point about mapmaking. “You have data, but that’s not enough to make a map. You also need a purpose. There’s no point in making a map unless you have something to say.” In other words: If you’re going to map blueberry production, why? Is it to compare the acreage of blueberry-producing regions? To compare it to other berry crops? A map is a statement: what are you trying to say? [Kenneth Field]
