GIS stands for geographical information system, which is the first thing to understand. It's a system that analyses, saves, and collects evidence for various organizations to use in order to make more educated and efficient decisions. GIS project management and other information technology projects have very little in common.
GIS is useful in a variety of sectors, including the environment. GIS consultants handle digital mapping data and do geographical statistics analysis. GIS mapping consultants create maps for customers based on data analysis.
The major emphasis for GIS consultants is generating maps for customers, determined from analytical data. Your work can be used in a wide range of disciplines.
