These polygons are a graphical representation of maps filed in Map Books, records of Santa Barbara County, California.
As a general rule, a Parcel Map is a vehicle of subdivision whereby four or fewer parcels are created simultaneously, whereas a Tract Map is a vehicle of subdivision whereby five or more parcels are created simultaneously. This book type contains Tract Maps or Final Maps. For more information, please see the County of Santa Barbara Surveyor's Manual at http://www.countyofsb.org/pwd/pwsurveyor.aspx?id=5116
Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

The data set was created to provide a spatial index for land survey record research.
Books of Maps are the second of six book types that have a common numbering system. (Maps and Surveys, Maps, Records of Surveys, Misc. Maps, Official Maps and Condominiums). The first entry was recorded on 4/8/1919. This is the oldest active book type. For more information, please see the downloads page at http://www.countyofsb.org/pwd/surveyor/pwd_rmlookup.aspx Polygons were either redrawn in CAD using distance and bearing measurements from the original record or traced from the County Assessor's Cadastral Parcel Landbase dataset.

DISCLAIMER: The information regarding properties contained in this data is compiled from various public sources, including tax parcel information, recorded documents, survey information and historical cartography sources. The actual size, shape, acreage, boundaries, zoning, legal basis and title to properties may differ significantly from that information shown in this data. The existence of a tax parcel or an Assessor's Parcel Number (APN) for a property is not indicative that a given parcel is lawfully created and is legally divided from surrounding property. We recommend that prior to making decisions regarding purchase, sale, permitting or use of real property that you consult with an appropriate professional, such as an attorney, land surveyor, real estate broker or land title company to ascertain the accurate status of a particular parcel of real property. Santa Barbara County employees in various offices will endeavor to answer questions from the public, but they cannot provide legal advice or any recommendations regarding a particular property outside the scope of their office.

The dataset is registered to the County Assessor's Cadastral Parcel Landbase dataset. The County assessor's cadastral Parcel Landbase dataset has no established level of accuracy and is based on printed Assessor's Map Books. Due to the nature of its construction the County Assessor's Cadastral Parcel Landbase dataset has varying degrees of positional precision. It is useful to distinguish between positional accuracy and positional precision. In the Assessor's Cadastral Parcel Landbase feature class, the former refers to the relative accuracy of a given group of spatially related parcel polygons. In other words, for any given polygon, are the neighboring polygons in a proper or accurate relationship spatially with our subject polygon? Subjectively we find that the Assessor's Cadastral Parcel Landbase feature class positional accuracy is good to excellent. On the other hand, positional precision refers to an actual ground location and how well any determinable cadastral point in the dataset is related to this established ground location. As stated previously, this will vary depending on its general location. In those areas which were initially spatially referenced to the Flood Control Topo Map Sets, which are the areas of Santa Barbara city, the Goleta valley, the Santa Ynez valley, and the Santa Maria valley, there is consistently a positional horizontal error of between 3 and 6 feet. The lower figure would be within the city blocks themselves, and the higher figure in the areas outside the numbered orthogonal blocks. Outside of this control set, the nature of the precision may be quite varied. In the unpopulated areas outside the control of the Knopf GPS road set, there may be variances of more than 100-200 feet. For the majority of the populated areas, any horizontal positional precision would be between these general values, and more closer to the lower side given a reasonable distance and tie-in to the Knopf GPS road set. Ultimately it must be remembered that for many of the more antique legal descriptions that might reference, say, a rancho line, that a precise location of any given cadastral point is by its nature an abstraction unless referenced by a modern record of survey, and even then there may be serious discrepancies in the various surveys that are available. The southern Tepusquet Rd area is a prime example, where it would take a survey and the signed acquiescence of all of the affected property owners to truly call that area spatially precise in cadastral terms. "Notice: Assessor Parcels are for tax assessment purposes only..." In general, Rancho areas with less monuments and fewer records of measured distances are less accurate, whereas urban areas with a higher density of recorded monuments and therefore more repeated distance measurements are more accurate.
Survey-collected GPS coordinate data from a small sample of monuments were compared to corresponding vertices in the County Assessorss Cadastral Parcel Landbase (Assessor's Parcel Layer). Verifying Survey data was obtained from horizontal positions derived by GPS observations holding Continuously Operating Reference Stations (CORS) or Control Points fixed as shown in Record of Survey Books, based on California Coordinate System 1983 (CCS83) 1991.35 epoch. The County Assessor's Cadastral Parcel Landbase dataset (Assessor's Parcel Layer) was obtained from the County Assessor.
