PUBLIC RESOURCES CODE

• DIVISION 8 - SURVEYING AND MAPPING
• REVISIONS
• EFFECTIVE JANUARY 1, 2006

2
PUBLIC RESOURCES CODE

• CHAPTER 1, CALIFORNIA COORDINATE SYSTEM (Revised)
• CHAPTER 2, TOPOGRAPHICAL MAPPING (No Change)
• CHAPTER 3, GEODETIC DATUMS AND THE CALIFORNIA
  SPATIAL REFERENCE NETWORK (New)
• CHAPTER 4, CALIFORNIA GEODETIC COORDINATES (New)
• CHAPTER 5, CALIFORNIA ORTHOMETRIC HEIGHTS (New)

3
PUBLIC RESOURCES CODE

• CHAPTER 1 California Coordinate System (Revised)
• Deletes incorrect references to geodetic
  positions
• Deletes portions that are covered in the new
  Chapter 3, Geodetic Datums and the California
  Spatial Reference Network
• Reduces the number of required reference
  stations from two to one
• If an accuracy is claimed for the CCS values,
  requires specific information to be shown and
  documented

4
PUBLIC RESOURCES CODE

• CHAPTER 3 Geodetic Datums and the California
  Spatial Reference Network (New)
• Establishes NAD83 as the official datum for
  horizontal positions and ellipsoid heights
• Establishes NAVD88 as the official datum for
  orthometric heights (elevations)
• Establishes the California Spatial Reference
  Network (CSRN) as the official control network
• Defines the requirements for stations included in
  the CSRN similar to the provisions defining the
  California Spatial Reference System - Horizontal
  in the previous CCS statutes

5
PUBLIC RESOURCES CODE

• CHAPTER 4 California Geodetic Coordinates (New)
• Establishes definitions and procedural
  requirements for certain geodetic surveys,
  similar to Chapter 1 (CCS)
• Provides that positions conforming to the
  statutes may be identified as California
  Geodetic Coordinates of 1983 (CGC83)
• Specifies the documentation required for CGC83
  surveys

6
PUBLIC RESOURCES CODE

• CHAPTER 5 California Orthometric Heights (New)
• Establishes definitions and procedural
  requirements for certain orthometric height
  surveys, similar to Chapter 1 (CCS) and Chapter 4
  (CGC)
• Provides that orthometric height values
  conforming to the statutes may be identified as
  California Orthometric Heights of 1988 (COH88)
• Specifies that the latest NGS geoid model shall
  be used when determining COH88 values from
  ellipsoid heights permits the use of local
  orthometric height correction models
• Specifies the documentation required for COH88
  surveys
