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.

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