Geographers study features of the earth, its inhabitants, and the land that its inhabitants live on.
In the past, geographers relied on maps for a lot of their work, but in today's world, global positioning systems (GPS) and geographic information systems (GIS) have changed the way that geographers work.
These advancements in technology give geographers the ability to identify trends and relationships in geographic data that would have previously been very difficult to detect. They are able to digitally represent detailed maps, charts, and other reports on demand, without having to take long excursions to gather data. This information can then be used to help businesses and the government make decisions -- such as where roads, homes, and landfills are built.
Because geography is such a broad discipline, most geographers choose to specialise in one of two broad areas:
Human geographers look for similarities between a region's culture and the geographic area the people inhabit. For instance, they may be able to identify cultural similarities between different people who live in cold coastal regions.
Physical geographers study the physical aspects of the earth. They look at things such as vegetation, climates, plants, and animals. They study these characteristics to understand the implications of the geography on a country or region.
