Traditionally we looked at maps as a guide on how to get from A to B.

 

As we move forward into the 21st century, the range of demands map-makers are called on to meet is almost limitless. It involves maps of forests, oilfields, agricultural crops and the ever-changing face of nations. Nowadays most maps are produced in digital form allowing them to be used in association with modern navigational aids such as GPS.

 

All maps are based on initial data provided by surveyors, which may involve field surveys, mapping calculations, aerial photography and laser scanning or remote-sensing surveys from satellites. In New Zealand, Land Information NZ is responsible for mapping and charting all of New Zealand and its territorial waters.
