A GIS expands the two-dimensional nature of a map to include information from a database. For example, a map can tell you where a river is located, but a GIS can show you where it is located and with the appropriate data layers can tell you what its average flow is, how clean the water is, how many people use it, or how close the nearest boat launch is.
People who work in the GIS field are called knowledge workers because a knowledge worker is a person working in one of the information industries and the GIS is an information industry so knowlege workers work there.

Earning a certificate in GIS is not the same as GIS certification. Unless the certificate program you attended results in a higher degree such as a Bachelor's or Master's degree, there are no initials you can place after your name. GIS certification is a fee-based process currently handled by the GIS Certification Institute (GISCI), that evaluates the GIS proficiency of an individual by assessing their experience, education, and contributions to the GIS industry. Those individuals awarded certification by the GISCI may place the acronym GISP (for GIS professional) after their name.
