    4.1.2.4.3.1 Distance Resolution  text  free text  The minimum distance measurable between two points, expressed in distance units of measure (e.g. the minimum allowable distance between two verticies).
    4.2.1.1  Altitude Datum  text  "NGVD29" "NAVD88" 
    "not applicable" 
    free text 
    The level surface of reference from which altitudes are measured, if applicable. NGVD29 = National Geodetic Vertical Datum of 1929; NAVD88 = North American Vertical Datum of 1988. 
    4.2.1.3  Altitude Units  text  "meters" "feet" 
    free text 
    Units in which altitudes are measured.

    "mean high water" 
    "mean sea level" 
    "land survey datum" 
    "not applicable" 
    free text 
    The surface of reference from which depths are measured, if applicable. 
    4.2.2.3  Depth Units  text  "meters" "feet" 
    free text 
    Units in which depths are measured. 
    Raster Data Only 
    4.1.2.4.2.1  Cell Width  real  > 0.0  The column width of a raster cell expressed in distance units of measure. 
    4.1.2.4.2.2  Cell Height  real  > 0.0  The row height of a raster cell expressed in distance units of measure. 
     
      
    If Geographic 
    4.1.1.1  Latitude Resolution  real  > 0.0  The minimum difference between two adjacent latitude values expressed in Geographic Coordinates Units of measure. 
    4.1.1.2  Longitude Resolution  real  > 0.0  The minimum difference between two adjacent longitude values expressed in Geographic Coordinates Units of measure. 
     
     
    If UTM 
    4.1.2.2.2.1 UTM Zone Number  text  14, 15, 15E, 16, free text Identifier for the UTM zone number(s) used. "15E" represents zone 15 extended to cover the entire state of Minnesota.
    No FGDC Equivalent  Coordinate Offsets or Adjustments  text  free text  An explanation of the magnitude, direction, etc. of any coordinate shifts or adjustments. For example "subtracted 4,700,000 from the Y coordinate." 
     
     
    If State Plane 
    4.1.2.2.4.1  SPCS Zone Identifier integer  2201, 
    2202, 
    2203 
    The Federal Information Processing Standard (FIPS) four-digit numeric code for the State Plane Coordinate Systems. In Minnesota, North = 2201, Central = 2202, and South = 2203. 
    No FGDC Equivalent  Coordinate Offsets or Adjustments  text  free text  An explanation of the magnitude, direction, etc. of any coordinate shifts or adjustments. 
     
    If County Coordinates 
    No FGDC Equivalent  County Coordinate Zone Identifier  integer  1-67  The county coordinate zone identifier number from The Minnesota County Coordinate System, A User's Handbook by Ken Whitehorn, Itasca Co. Surveyor,  published by Precision Measuring Systems, 1998. 
    Note: Some coordinate zones include multiple counties and some large counties have multiple coordinate zones. 
    Note: These coordinate IDs are not the same as county IDs.
    Note: A list of the codes is available in the DataLogr help menus.
    No FGDC Equivalent  Coordinate Offsets or Adjustments  text  free text  An explanation of the magnitude, direction, etc. of any coordinate shifts or adjustments.
