The classifications in this two-level series perform duties associated with developing and maintaining the County cadastral mapping system.  Incumbents apply cartographic principles and practices to maintain records and cadastral and geographic information system (GIS) maps aiding the Assessor's Office in the identification, location, inventory and mapping of land for assessment and valuation of property.  All positions prepare a variety of cartographic maps, solve problems requiring knowledge of the subject matter of surveying, mapping and legal ownership.  Individual positions perform, at varying levels of difficulty, all types of cartographic projects from basic preparation of partitions, segregations and consolidations to more complex projects requiring research and resolution of ownership, boundary and taxing district issues.

This classification is entry-level in the cartographer/GIS technician series, and is distinguished by performing standard and routine cartographer/GIS functions, by the limited degree of independence, judgment and responsibility of work performed and by receiving a greater degree of supervision than the cartographer/GIS technician 2.
