CARTOGRAPHER/GIS TECHNICIAN 2
Pay Range GC16

INTRODUCTION

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, 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 journey-level in the cartographer/GIS technician series, and is distinguished by performing complex cartographic functions, by a greater degree of independence, judgment and responsibility.

EXAMPLES OF PRINCIPAL DUTIES  (Duties assigned to this classification include, but are not limited to, the following examples.  Any one position may not perform all listed tasks.)

1. Plot annexations, formations, mergers, consolidations and withdrawals of taxing districts on code and cadastral and/or GIS maps; record changes on maps, tax lot records and assessment rolls; prepare new boundary maps for new districts.

2. Prepare segregation, consolidations and partitions of property by using coordinate geometry in plotting new boundaries on maps and computing acreage of new parcel(s), assign new tax lot and account number and prepare new prints of revised maps for map books.

3. Develop, use and maintain maps using the GIS-based mapping system to construct complex maps such as base control maps, cadastral maps and specialized maps from beginning to finalization; revise maps to conform to official government land surveys, highway maps, BLM public land surveys and new aerial photos.

4. Receive and review deed records and other instruments indicating ownership changes of property and change assessment roll, tax lot card and other pertinent records.

5. Review subdivision and condominiums for conformance to statutes and revise maps and assessment roll to conform and reflect new subdivisions or condominiums.

6. Utilize the GIS system to input and update basemaps, plot, compare to existing maps and analyze differences, and to determine and present information in cartographic and statistical formats.

7. Perform extensive title searches to determine ownership on questioned properties; review ownership boundary, taxing district, tax code area issues; interpret legal descriptions; assist other departments, agencies and the public with property questions or complaints regarding cadastral and/or GIS maps and records.

8. Maintain those portions of the GIS database Assessor is responsible for; work with other GIS users and the Department of Revenue to protect the integrity of the GIS application for the Assessor and other users of the GIS system.

9. Prepare and maintain records, reports and statistical data.
