Common use of Horizontal Coordinate System Definition Clause in Contracts

Horizontal Coordinate System Definition. SCAG needs to know and agree to the data projection. It would be very unusual to accept a projection that does not have standard parameters. Data will most often be required in North American Datum 1983 UTM zone 11. The parameters for this projection are: Projection: Transverse Mercator Parameters False Easting 500000.0000000 False Northing: 0.0000000 Central Meridian: -117.0000000 Scale_Factor: 0.999600000 Latitude of Origin: 0 Linear Unit: Meter (1.000) Geographic Coordinate System: Name: GCS_North_American_1983 Angular Unit: Degree (0.017453292519943295) Prime Meridian: Greenwich (0.000000000000) Datum: D_North_American_1983 Spheroid: GRS_1980 Semimajor Axis: 6378137.000000000000 Semiminor Axis: 6356752.314140356100 Inverse Flattening: 298.2572221010000200 SCAG also requires all codes used in any spatial data set to be provided in an agreed upon electronic format. The FGDC standard for data documentation is a very complete standard covering every kind of spatial data. What follows are the items for metadata documentation in datasets typically received at SCAG. Generally SCAG receives data pertaining to phenomena on the earth’s surface in a vector form of points, lines, or polygons. Other types of data, which might include such forms as raster data and imagery data or some theme as subsurface water depth, would require reconsideration of some of the specific items required. The types of metadata information outlined at the first and second levels below are required of all data. The outline numbers are from FGDC-STD-001-1998 “Content Standard for Digital Geospatial Metadata.” The actual fields that require input are underlined
