Stewards should submit a brief description of the dataset version they are proposing as the candidate dataset for inclusion into the DWR GIS Atlas. Information on source, completeness, methods, or other descriptions of how and where this dataset comes from should be included. If appropriate, some discussion about alternative versions of the data and cursory comparisons to those alternatives should be included.

This dataset is a combination of features that can be extracted from the Detailed Analysis Units (DAU).

Summary

Detailed Analysis’s Units DAU by COUNTY. DAU boundaries to match CAL FIRE dataset. Cal-Atlas cnty24k09_1_poly.

Description

Detailed Analysis Unit-(DAU) Convergence via County Boundary cnty24k09, (*See metadata for cnty24k09, Cal-Atlas), State of California.

The existing DAU boundaries were clipped via Cal-Atlas cnty24k09 by Michael L. Serna, NRO via ArcMap 10.1. DAU’s were sent out to: Northern Region Office (NRO), North Central Region Office (NCRO), South Central Region Office (SCRO) and Southern Region Office (SRO) respectively.

Collaboration was by Department of Water Resources, Region Office personnel, Michael L. Serna, NRO, Jason Harbaugh - NCRO, Cynthia Moffett - SCRO and Robert Fastenau - SRO with the final merge of all data into a cohesive workable.

This version was derived because the existing “dau_v2_105 nad27” Detailed Analysis Unit feature class boundaries contained a multitude of variant sliver acreages along all DAU and county boundary lines through-out the State of California.

Each region office was sent their respective features where they exposed the DAU’s sliver anomalies. They subsequently merged the variant slivers into the proper DAUs. Upon completion, the DAU feature classes were sent back for assemblage. These features are reachable by County\DAU. This allows the county boundaries, the DAU boundaries and the State of California Boundary to match Cal-Atlas cnty24k09_1.

cnty24k09_1_poly metadata Summary:

Ideally, state and federal agencies should be using the same framework data for common themes such as county boundaries. This layer provides an initial offering as "best available" at 1:24,000 scale. Additional improvements, including a review of data sources for the coastline, can be added over time based on interagency review and agreement on proposed changes.

cnty24k09_1_poly metadata Description:

In late 1996, the Dept. of Conservation (DOC) surveyed state and federal agencies about the county boundary coverage they used. As a result, DOC adopted the 1:24,000 (24K) scale U.S. Bureau of Reclamation (USBR) dataset (USGS source) for their Farmland Mapping and Monitoring Program (FMMP) but with several modifications. Detailed documentation of these changes is provided by FMMP and included in the lineage section of the metadata. A dataset named cnty24k97_1 was made available (approximately 2004) through the California Department of Forestry and Fire Protection - Fire and Resource Assessment Program (CDF - FRAP) and the California Spatial Information Library (CaSIL). In late 2006, the Department of Fish and Game (DFG) reviewed cnty24k97_1. Comparisons were made to a high-quality 100K dataset (co100a/county100k from the former Teale Data Center GIS Solutions Group) and legal boundary descriptions from ( http://www.leginfo.ca.gov ). The cnty24k97_1 dataset was missing Anacapa and Santa Barbara islands. DFG added the missing islands using previously-digitized coastline data (coastn27 of State Lands Commission origin), corrected a few county boundaries, built region topology, added additional attributes, and renamed the dataset to county24k. In 2007, the California Mapping Coordinating Committee (CMCC) requested that the California Department of Forestry and Fire Protection (CAL FIRE) resume stewardship of the statewide county boundaries data. CAL FIRE adopted the changes made by DFG and collected additional suggestions for the county data from DFG, DOC, and local government agencies. CAL FIRE incorporated these suggestions into the latest revision, which has been renamed cnty24k09_1. Detailed documentation of changes is included in the Process Step section of the metadata.
