Mapping and Digital Data Standards (MDDS) in Brief

Previous

1. Throughout this guidance, reference is made to MDDS; therefore, it is important for the reader to review and understand thoroughly the elements of this document. Copies and information regarding MDDS can be obtained by calling the Bureau of Geographic Information Analysis (BGIA) at 609/777-0672 or through the DEP Electronic Data Interchange Manual (EDI). [pdf] Following is a summary of some of the key elements of this document.
1. MDDS references Chapter 218, Laws of the State of New Jersey 1989, that require that geographic data be submitted to the DEP in New Jersey State Plane Coordinates (NJSPC) referenced to North American Datum of 1983 (NAD83) horizontal geodetic datum. NJSPC is the geographic reference system in the horizontal plane defining the spatial relationship of points or features in new Jersey. State Plane Survey feet are the specific units of measurement used by the Department.
   
   
2. All base maps regardless of scale must meet the standards defined in the United States National Map Accuracy Standards (NMAS), or the person submitting the data must provide the Department with an explanation of why it is appropriate to deviate from NMAS. However, for large scale maps (larger than 1:2400), post processed or corrected GPS coordinates or an appropriate survey standard is acceptable. Please document the standard used.
   
   Note: These explanations are to be included with information submitted with Metadata requirements for digital map submissions, outlined in section C of this document.
   
   
3. Geographic data submitted to NJDEP in digital format is to be consistent with the electronic formats identified in MDDS Table 2. Note: Since digital maps will be processed and stored by DEP staff other then those in the lead remedial program, map, site information and metadata (for detailed explanations regarding metadata, see section C below) must be submitted on their own diskette independent of HAZSITE data or other digitally submitted information. In order to facilitate appropriate distribution of these diskettes through the Department, it is requested that they be individually labeled with the following information.
   
   
• Title - GIS Data
• Site Name
• SRP ID#
• Diskette Contents
  • Maps - CEAs and/or ESAs
  • Site Info file
  • Metadata
    
    

Additional detailed information regarding NJDEP GIS standards and practices can be obtained in the hard copy of the "New Jersey GIS Resource Guide -1996" for $20.00 from DEP Map Sales, PO Box 420, Trenton, 08625-0420; at 609/777-1039. The document is also available on CD ROM in HTML format. Please order Series 2, Volume I, "GIS Tools for Decision Making" ($30.00 from Map Sales). Note: Additional GIS reference data is also available on 4 NJDEP CD ROMs; see section D of this document for more detail.
