Gather, analyze and verify data to make sure maps are accurate.
Computers have transformed the mapmaking industry. Instead of creating two-dimensional drawings, modern Mapmakers now integrate a variety of information into maps, including the site’s geology, business potential, ecosystem, and structural integrity. A GIS Mapping Technician makes these fancy maps.
As a GIS Mapping Technician, you spend the vast majority of your day in front of a computer. You study information that comes from Surveyors, Engineers, Biologists, and Cartographers. GIS Mapping Technicians may work with traditional map-based data, such as the distance between point A and point B, or with nontraditional information, such as population density, rainfall, and soil samples. You may also look at aerial photographs of the area.
Once you’ve analyzed the information, you input it into the computer and generate a three-dimensional map containing all the data you’ve received. You format the information in such a way that it’s easy to use.
Some companies require you to head into the field on occasion and make your own observations. You may do things like measuring the distance between two landmarks using specialized equipment. You’ll spend a lot of time hiking and measuring.
Other companies replace this fieldwork with customer service work. You meet with clients and explain your maps. You also attend conferences, talk about your work, and promote the services your company provides. Additionally, you train people to use GIS systems.
