A Geographic Information System (GIS) technology converts geographic features and attributes to a digitized database, creating a multilayered map of Kern County. Assessor GIS database consists of feature classes such as parcel numbers, assessor map books, tax rate areas, owner/assessee names, use codes, and assessed values.
The Assessor's mapping system is powered by ArcGIS software by Esri. The system models every parcel boundary in Kern County, as well as ancillary features, such as street, railroad and canal centerlines, section corners, section lines, public easements, and legal lot lines. Some ancillary feature sets are incomplete, but are being added on an ongoing basis.
The official assessment maps currently consist of nearly 17,000 hardcopy map sheets, mostly hand-drawn, drafted on vellum and mylar sheets. As converting hand-drawn maps will take time to complete, our current GIS data has varying degrees of accuracy.
Though GIS maps and data are offered for convenience, hardcopy Assessor Maps are still the official maps for property assessment purposes. GIS maps are available on an as-is basis.
KERN GIS PARCEL DATA, is available in two different edition types: a Preliminary Edition and a Final Edition. Each edition represents a snapshot-in-time of a continually changing dataset.
The Final Edition is published mid July, after the July 1st tax roll close, and represents the statutory "final tax roll" which the Assessor delivers to the Auditor-Controller and is used to generate property tax bills in November. Archived Final Editions are available back to 2004.
The Preliminary Edition contains the most current ownership information available as well as recent parcel boundary changes, but due to its preliminary nature will contain some inconsistencies, such as incorrect valuations, interim parcel boundaries and other anomalies representing work in progress.Preliminary Editions will be released as frequently as is deemed appropriate, based on factors such as workload and demand.
The most recent edition available is: 2019 Preliminary 06 Edition, published 01-06-2019.
Each GIS dataset edition includes 4 distinct feature classes:
These feature classes are provided in both Esri Shapefile and Esri File Geodatabase formats. The contents are identical in each format, except for technical differences in geometry support inherent to each format. (Shapefiles do not support circular curves, whereas File Geodatabases do).
Esri Shapefile is an open format, so it is compatible with a variety of GIS software packages whether proprietary, freeware, or open source.
Esri File Geodatabase is a proprietary format, but Esri has released a developer API. Non-developers can only use the File Geodatabase format within the ArcGIS software environment.
Each GIS dataset edition includes 6 distinct attribute tables. These tables come in dBase format (DBF) for use with the Shapefiles, and they are also included within the File Geodatabase as standalone tables. In either case, joining is required. The attribute tables are as follows:
Also included in each dataset edition is a Microsoft Access 2010 database file (ACCDB), consisting of unfiltered, raw data, extracted from the county's mainframe system. It is not suitable for joining with the GIS feature classes. The 6 dBase files listed above were generated using queries and macros embedded in the Access database and is provided for those requiring the complete, unaltered tax roll.
