Geographers use maps and global positioning systems in their work.
Geographers study the Earth and the distribution of its land, features, and inhabitants. They also examine political or cultural structures and study the physical and human geographic characteristics of regions ranging in scale from local to global.
Geographers typically do the following:
- Gather geographic data through field observations, maps, photographs, satellite imagery, and censuses
- Conduct research via surveys, interviews, and focus groups
- Create and modify maps or other visual representations of geographic data
- Analyze the geographic distribution of physical and cultural characteristics and occurrences
- Collect, analyze, and display geographic data with Geographic Information Systems (GIS)
- Write reports and present research findings
- Assist, advise, or lead others in using GIS and geographic data
- Link geographic data with data pertaining to a particular specialty, such as economics, the environment, health, or politics
Geographers use several technologies in their work, such as GIS, remote sensing, and global positioning systems (GPS). Geographers use GIS to find relationships and trends in geographic data. These systems allow geographers to present data visually as maps, reports, and charts. For example, geographers can overlay aerial or satellite images with GIS data, such as population density in a given region, and create digital maps. They then use the maps to inform governments, businesses, and the general public on a variety of issues, such as developing marketing strategies; planning homes, roads, and landfills; and responding to disasters.
The following are examples of types of geographers:
Physical geographers examine the physical aspects of a region and how they relate to humans. They study features of the natural environment, such as landforms, climates, soils, natural hazards, water, and plants. For example, physical geographers may map where a natural resource occurs in a country or study the implications of proposed economic development on the surrounding natural environment.
Human geographers analyze the organization of human activity and its relationships with the physical environment. Human geographers often combine issues from other disciplines into their research, which may include economic, environmental, medical, cultural, social, or political topics. In their research, some human geographers rely primarily on statistical techniques or quantitative methods, and others rely on nonstatistical sources or qualitative methods, such as field observations and interviews.
Geographers often work on projects with people in related fields. For example, geographers may work with urban planners, civil engineers, legislators, or real estate professionals to determine the best location for new public transportation infrastructure.
Some people with a geography degree become postsecondary teachers.
Many people who study geography and who use GIS in their work are employed as surveyors, cartographers and photogrammetrists, surveying and mapping technicians, urban and regional planners, or geoscientists.
