DEFINITION

To create and maintain maps and other geographic source data by manual and automated means for use by County departments and other public agencies, consultants and contractors and the public; to create and maintain assigned aspects of the Geographic Information System (GIS) database; to analyze GIS data and information; and to generate maps and reports as requested.

DISTINGUISHING CHARACTERISTICS

Geographic Information System Technician I
This is the entry-level class in the Geographic Information System Technician series.  This class is distinguished from the Geographic Information System Technician II by the performance of the more routine tasks and duties assigned to positions within this series.  Employees at this level are not expected to perform with the same independence of direction and judgment on matters allocated to the journey level.  Since this class is typically used as an entry class, employees may have only limited or no directly related work experience.  Employees work under immediate supervision while learning job tasks.

Geographic Information System Technician II
This is the full journey level class within the Geographic Information System Technician series.  This class is distinguished from the Geographic Information System Technician I level by the assignment of the full range of duties assigned including the more difficult or complex work.  Employees 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 within the work unit.  Positions in this class are flexibly staffed and are normally filled by advancement from the entry level.

This class is distinguished from the Senior Geographic Information Technician in that the latter may exercise technical and functional supervision over technical and clerical staff and performs the more difficult and complex mapping system and data management duties.

SUPERVISION RECEIVED AND EXERCISED

Geographic Information System Technician I
Receives immediate supervision from an assigned supervisor, and may receive technical and functional supervision from a higher level staff.

Geographic Information System Technician II
Receives general supervision from an assigned supervisor, and may receive technical and functional supervision from a higher level staff.

May exercise technical and functional supervision over less experienced technical staff.
