Converted to California Teale Albers NAD83 by the California Department of Fish and Game -- BEGIN ORIGINAL METADATA - THIS INFORMATION MAY NOT BE CURRENT -- CALIFORNIA DEPARTMENT OF FISH AND GAME GIS METADATA California Geographic Names SHAPEFILE NAME: cagnis DATA PATH: METADATA FILE: cagnis.txt METADATA DATE: November 2000 METADATA UPDATE: January 2001 *** DRAFT *** METADATA PATH: * Processing metadata follow the metadata text * SHAPEFILE DESCRIPTION The cagnis shapefile contains information on names, locations, and types of geographic features in California. The source of this shapefile is a custom state extract from the U.S. Geological Survey's Geographic Names Information System (GNIS). GNIS contains geographic names for all known places, features, and areas in the United States that are identified by a proper name. In cagnis, each feature is located by geographic coordinates and is referenced to the 1:24,000-scale USGS topographic map on which it is shown. cagnis contains the 66 different features type defined by GNIS as of October 2000. Users are advised that these feature types are not exhaustive. For example, selecting the "school" type will not give you every California school, but it will furnish a large number of school locations. And there may be features in GNIS that are not yet represented on USGS map sheets. cagnis is useful for furnishing landmarks on plots and can also serve as a base data layer. The features types and names help to orient the viewer and give a sense of scale to the plot. Complete documentation on the GNIS is available at http://mapping.usgs.gov/www/gnis/ SPECIAL NOTE FOR CALIFORNIA DEPARTMENT OF FISH AND GAME USERS The USGS has determined that the locations and names of caves are sensitive information. The Department has public trust responsibilities to protect fish, wildlife, and plant resources and the habitats on which they depend, and has therefore maintained legacy GNIS cave references in cagnis. Users are urged to exercise discretion in the release of these data. VITAL STATISTICS Datum: NAD 27 Projection: Albers Units: Meters 1st Std. Parallel: 34 00 00 (34.0 degrees N) 2nd Std.

APPENDIX B.--Geographic Names Information System (GNIS) Feature Class Definitions The feature class terms and abbreviations currently consist of nine or fewer letters and were chosen for computer search and retrieval pur- poses. They do not necessarily represent terminology for the identifi- cation of all kinds of cultural and natural features. Although some of the terms may agree with dictionary definitions, they represent more generalized categories. Some commonly used generics are listed in paren- theses at the end of each entry to assist in understanding the range of cultural and natural entities represented by the term. Refer to the Reference Data Base to retrieve all generics thus far encountered in geographic names compilation. In most instances a plural form is listed as if it were singular; for example, archipelago or islands would be categorized as island. The terms and the definitions are as follows: airport - manmade facility maintained for the use of aircraft (airfield, airstrip, landing field, landing strip). arch - natural arch-like opening in a rock mass (bridge, natural bridge, sea arch). area - any one of several areally extensive natural features not included in other categories (badlands, barren, delta, fan, garden). arroyo - watercourse or channel through which water may occasionally flow (coulee, draw, gully, wash). bar - natural accumulation of sand, gravel, or alluvium forming an underwater or exposed embankment (ledge, reef, sandbar, shoal, spit). basin - natural depression or relatively low area enclosed by higher land (amphitheater, cirque, pit, sink). bay - indentation of a coastline or shoreline enclosing a part of a body of water;

Note that GNIS may contain multiple points for a single unique feature such as a river (consisting of primary coordinate and one or more secondary coordinates). The count figures presented here reflect only one point feature instance. This 11/09/2000 revision contains 104,133 single unique features; an increase of 17,994. The individual feature type counts are listed in comma-delimited format below.

USGS GNIS Staff provided some DFG-requested fields in the delivered .txt files: Ca_list1.txt - File contains all primary data Column 1 - Feature ID (named ID in November 2000 processing of CA data) Column 2 - Gipsy ID (named GNIS_ID by DFG in cagnis) Column 12 - Cell Name (7.5' USGS Quadrangle Map Name) Ca_list2_coord.txt - File contains all secondary coordinates for features that have more than one coordinate, e.g. for streams, the mouth is the primary coordinate. Secondary coordinates (and additional shapepoints) are posted for every quad the stream flows through. Column 2 - Sequence Number (starts with sequence number 2) "Feature ID" is the current GNIS name of its primary key, but is named "ID" in this DFG rendition of the California extract (as it was in previous DFG versions). Values of "ID" in the cagnis are current as primary keys, except for FEATURE_TYPE = "cave". New versions of GNIS do not include the feature type "cave", due to federal legislation mandating their treatment as sensitive data. DFG is maintaining legacy GNIS cave data as part of its public trust responsibilities. DFG generated a special set of IDs for caves: The ID for caves is "999" + the legacy GNIS_ID. "Gipsy ID" is a legacy, obsolete GNIS primary key. DFG is maintaining the legacy values under the field name "GNIS_ID" for references to features coded in USEPA's River Reach File under the "Primary Name Code" (PNMCD) for hydrographic features (rivers and streams). DFG implements "GNIS_ID" now as a numeric instead of a character field. The Cell Name field is the USGS 7.5' Quadname and is a new field. The elevat_ft field is now numeric. The Sequence Number field is new and contains the sequence number for those features that have more than one coordinate. REVISION EXCLUSIONS The old and new versions of the California extract of GNIS contain more fields than are represented in the DFG processed GIS dataset. DFG dropped fields where these were either very sparsely populated or could be derived from other GIS layers such as county or state FIPS codes. There were many spurious data points outside of California. Most of the points that were reasonably off-shore were kept. Those north, south and east into Oregon, Arizona, and Nevada respectively were clipped using a 1 kilometer buffer around the California border. ==end of file cagnis.txt -- END ORIGINAL METADATA --
