This is the second-level class in the Geographic Information Systems (GIS) Analyst series. Incumbents perform work of a professional rather than technical nature, utilizing skills that require an understanding of analytical procedures and processes. Positions at this level receive only occasional instruction or assistance as new or unusual situations arise, and are fully aware of the operating procedures and policies of the work unit. This class is distinguished from the Principal Geographic Information Systems Analyst in that the latter requires specialized, functional or technical expertise beyond the journey level and is responsible for designing and developing more complex geographic information systems, networks and applications. Concurrently or alternatively, a Principal Geographic Information Systems Analyst may supervise subordinate GIS Analysts and serve as the GIS program coordinator for a large department.
