Geographers typically do the following:
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.
Geographers with a bachelor’s degree qualify for most entry-level jobs and for positions with the federal government. Geographers outside of the federal government may need a master’s degree in geography or in Geographic Information Systems (GIS). Some positions allow candidates to substitute work experience or GIS proficiency for an advanced degree. Top research positions usually require a Ph.D., or a master’s degree and several years of relevant work experience.
Most geography programs include courses in both physical and human geography, statistics or math, remote sensing, and GIS. In addition, courses in specialized areas of expertise are becoming increasingly important because the geography field is broad and interdisciplinary. For example, business, economics, or real estate courses are becoming increasingly important for geographers working in private industry.
Although certification is not required, most positions require geographers to be proficient in GIS, and certification can demonstrate a level of professional expertise. The GIS Certification Institute offers the GIS Professional (GISP) certification for geographers. Candidates may qualify for certification through a combination of education, professional experience, and contributions to the profession, such as publications or participation in conferences. The American Society for Photogrammetry and Remote Sensing also offers certification in GIS. Candidates may qualify for certification with 3 years of experience in GIS, four references, and the passing of a written exam.
