Conclusion

Maps have served an important role in the opening of frontiers. Early explorers charted new territory on maps. Settlers relied on maps for the division of land. The role of maps in the exploration of the unknown is still evident in the exploration of resources such as oil.

Cartography now faces its own frontier. The frontier is a new medium, a medium that goes beyond paper and the individual, static map to one that presents a more dynamic view of the world. A medium that changes how space and place are conceived.

The frontier is the boundary between the known and the unknown. As each of us comes to know the spatial world in which we live, we push back the boundary of our own personal frontier. We do so by learning the streets of a city or the hills and valleys of a surrounding countryside.

So it is too with the world beyond our own personal experience. Here we use maps to push back the frontier - to find out where things are located and how things are related to each other. While maps help us to push back the frontier, it is always out there. There is always a point in our understanding of the world where the known ends and the unknown begins.

 

We all exist up to the boundaries of our own frontier. Maps can help us move beyond these boundaries. They can help us chart a new world.
