CON500GN also contains elevation range polygons at 500-foot intervals, but CON500GN was weeded to remove the extreme angular stair-stepping in the linework of CON500. This stair-stepping is a by-product of using a raster data source. In addition to the weeding, dangles were deleted, arcs were unsplit to remove thousands of unnecessary nodes, and the feature class was copied to single precision. The result is a more aesthetically pleasing presentation, a much smaller data volume, and much faster screen draws.CON500GN is a smaller, faster, generalized version of CON500, a 500-foot contour interval feature class for California.Caltrans19991201con500gncon500gnvector digital datahttp://www.dot.ca.gov/hq/tsip/gis/datalibrary/gisdatalibrary.htmlUnknownpublication date20001101-124.411343-114.13147342.00003032.534028-124.411343-114.13147332.53402842.000030Shapefile Caltrans TSI/GIS Data Branch Metadata Coordinator mailing and physical address Sacramento CA 95814

Due the weeding process used in creating this feature class, planimetric shifts in the linework from the original CON500 are visible. However, given the generalized, abstract nature of contour lines this should not impact the utility of the data.CON500GN is complete as of 20001101.Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 9.1.0.722con500gn-124.411343-114.13147342.0000332.5340281-124.411343-114.13147342.0000332.5340281ISO 19115 Geographic Information - MetadataDIS_ESRI1.0dataset002file://\\svhqs02\newgis\data\shapes\geo83\state\con500gn.shpLocal Area Network24.270ShapefileVectorSimplePolygonFALSE16046FALSEFALSEG-polygon16046GCS_North_American_1983Decimal degrees0.0000000.000000North American Datum of 1983Geodetic Reference System 806378137.000000298.257222GCS_North_American_198316046con500gnFeature Class16046CON500GN polygons represent generalized 500-foot contour intervals in California.Caltrans TSI/GIS Data BranchFIDFIDOID400Internal feature number.ESRISequential unique whole numbers that are automatically generated.ShapeShapeGeometry000Feature geometry.ESRICoordinates defining the features.AREAAREANumber163Caltrans TSI/GIS Data BranchN/APERIMETERPERIMETERNumber163Caltrans TSI/GIS Data BranchN/ACON500GN_CON500GN_Number11Caltrans TSI/GIS Data BranchN/ACON500GN_ICON500GN_INumber11Caltrans TSI/GIS Data BranchIdentifierRANGE_CODERANGE_CODENumber11Caltrans TSI/GIS Data Branch130Numeric code corresponding to 500 feet of elevation.20090505
