If you’re interested in pursuing a career in GIS, there are many resources to consult. This article from GIS Lounge is a great place to start; it includes information about learning GIS skills, getting experience, and finding a job. As you look at job listings, you’ll find a number of titles and descriptions. Because GIS is still a relatively new and growing field – not just in size, but in complexity – there are not necessarily firmly agreed upon or established job titles, but some commonly-used titles and descriptions do exist. Follow this discussion on StackExchange to see what some GIS professionals and technicians in the field have to say about these. (Pro tip: StackExchange is a great discussion board for GIS technical help, too!)
