County Precinct Archive 1998

A 1998 archive of county precincts for Jefferson County, Colorado. The couty precinct is a seven-digit code. That code conforms to the following format: DIGIT 1: FEDERAL HOUSE (CONGRESSIONAL) DISTRICT DIGITS 2-3: STATE SENATE DISTRICT DIGITS 4-5: STATE HOUSE DISTRICT DIGITS 6-7: UNIQUE PRECINCT IDENTIFIER (PER COLUMNS 1-5) As an example, precinct 6302506 is the 6th unique precinct serving the combination of the 6th Congressional district, 30th State Senate district, and 25th State House district. County precinct data, along with all core jurisdictional data pertinent to elections, was maintained in a GIS production database by IT Development via specialized tools. Source data was the Geocode coverage which contained polygonal data to which jurisdictional attributes were attached. Geocode was an atomic-level polygonal coverage, by which we mean each polygon feature carried the core political data (county precinct {with federal house, state house and state senate districts embedded within}, city code {municipal status}, city ward, city precinct, commissioner district, regional transportation district {RTD}, traffic impact fee area {TIFA}, south jeffco local improvement district) used by the Elections Office in the determination of ballot styles. Whenever editing to Geocode geometry occurred or whenever Geocode political atttribution was edited, Geocode was dissolved for each core political component (column) by nightly enterprise processing. In this case, CountyPrecinct results from a dissolve of Geocode's CPCNT column. All derivatives, like CountyPrecinct, were then re-freshed in the County's spatial data warehouse. Data is in State Plane Grid Coordinates, Colorado Central Zone, NAD83 (US feet).科罗拉多州杰斐逊县（Jefferson County）1998年县级选区档案数据集。该县级选区采用七位编码，编码格式如下：第1位：联邦众议院（国会）选区；第2-3位：州参议院选区；第4-5位：州众议院选区；第6-7位：唯一选区标识符（基于第1-5位编码组合）。例如，选区编码6302506即对应第6国会选区、第30州参议院选区及第25州众议院选区组合下的第6个唯一选区。 县级选区数据及所有与选举相关的核心管辖区域数据，均由IT开发团队（IT Development）通过专用工具维护于地理信息系统（GIS）生产数据库中。该数据集的源数据为地理编码覆盖层（Geocode coverage），其包含附有管辖区域属性的多边形数据。地理编码覆盖层属于原子级多边形覆盖层，即每个多边形要素均携带有选举办公室用于确定选票样式的核心政治属性数据，具体包括：内嵌联邦众议院、州众议院与州参议院选区信息的县级选区、城市代码（市政地位）、城市分区、城市选区、专员辖区、区域交通局（RTD）辖区、交通影响费区（TIFA）以及南杰斐逊县地方改善区。每当对地理编码覆盖层的几何图形或政治属性进行编辑时，系统都会通过夜间企业级处理流程，针对每个核心政治要素（字段）对地理编码覆盖层执行融合消解操作。本数据集CountyPrecinct图层即通过对地理编码覆盖层的CPCNT字段执行融合消解操作生成。所有衍生数据集（如CountyPrecinct）随后均会更新至该县空间数据仓库中。本数据集采用科罗拉多州中央区状态平面网格坐标系（State Plane Grid Coordinates, Colorado Central Zone），基准为NAD83，单位为美制英尺（US feet）。
