GIS Role

As the title would suggest, a GIS Developer (or a GIS Specialist) works as a software developer to help design and develop GIS programming applications and tools. They also work to maintain GIS software programs in accordance with the needs of the organizations and/or clients.

GIS or a Geographic Information System refers to a framework that handles gathering, managing, and analyzing data. With geography as the basis of the framework, GIS makes use of several types of data.

GIS makes use of maps and 3D scenes to organize layers of data via spatial analysis.

Through this, GIS mapping is able to offer deeper insight into data sets that we normally may not be able to perceive. This could include patterns, situations, relationships, links, etc; allowing us to make better-informed decisions when interpreting data.

GIS software is used in nearly every industry by hundreds of thousands of organizations and businesses. GIS is used to generate maps that can be used to communicate, analyze, share information, and help solve complex problems around the world.
