USGS CMG "Activity ID" Definition

• The Activity-ID represents an activity (usually field work) by a unique character string.
  

  An InfoBank Activity-ID has four components

  CMG InfoBank Activity ID

  P-L-YY-RR or P-LL-YY-RR

  Platform A single letter abbreviation of the platform's full name. Leg A number (1-2 alphanumerics) corresponding to a "cruise" or "leg" for a particular platform in a particular year. Year The last two digits of the year the activity started. Region A 2-letter abbreviation of the general activity area.    Disclaimer

  Ex:  J-4-92-SF  or  J492SF
       J         = platform   ("Johnston" or "Jordan")
         4       = leg        (4th cruise for this platform in 1992)
           92    = year       (1992)
              SF = region     (San Francisco area)
  
  

• Each component can be separated by a hyphen.

  Ex:  J-4-92-SF and J492SF represent the same activity.
  

• The hyphenated Activity-ID is preferable for readability and is used as the first component in file names.
• The non-hypendated Activity_ID version is for convenience and is used for directory names.

• Unsure of what letter to use for the platform component? -- check defined platforms.
• Unsure of what letters to use for the region component? -- check defined regions.
• Unsure of what naming convention to use for a geodetic survey? -- check defined geodetic Activity-ID names.
• Unsure of what thumbnail map boundary limits to use for the Activity ID? -- check thumbnail boundary limits.

• Constructing a new ID rarely conflicts with an existing ID.
• If this occurs, first consider using an alternate "region" component.
• If it still conflicts, contact Clint Steele for advice and assistance.

  For example, below is a list of some of the activities within the USGS CMG InfoBank:

   
     F-1-88-SC  or F188SC    = Farnella, Leg  1, 1988, Southern California
  
     F-12-88-NC or F1288NC   = Farnella, Leg 12, 1988, Northern California
  
     J-3-82-TB  or J382TB    = Johnston, Leg  3, 1982, Tomales Bay
  
     L-3-80-NP  or L380NP    = Lee,      Leg  3, 1980, North Pacific
  

  Modified CMG InfoBank Activity ID for Geodetic Surveys

  CMG InfoBank Activity ID for Geodetic Surveys

  S-S#-YY-RR

  Site A 2-letter abbreviation of the site's full name. Count A sequentially assigned counter (1..9, then A..Z) for each visit to a site in a particular year. Year The last two digits of the year the activity started. Region A 2-letter abbreviation of the general activity area.

  Standardized CMG InfoBank Activity ID Pseudonyms exist for:

  Woods Hole Field Center Cruise Serial Number	YY###	Year The last two digits of the year the activity started. Number A unique, sequentially assigned 3-digit number.
  Woods Hole Field Center Cruise ID	PPPPYY###	Platform 4-character platform ID Year The last two digits of the year the activity started. Number A unique, sequentially assigned 3-digit number.
  CMG Geodetic Total Station ID	YYMMDDO	Year The last two digits of the year the activity started. Month 2-digit month number. Day 2-digit day number. Order A single letter representing the sequential order of sites visited that day (e.g., A=1st, B=2nd, C=3rd...)
  USGS Florida Integrated Science Center - St. Petersburg	YYPPP##	Year The last two digits of the year the activity started. Project 3-letter abbreviation for the project the data were collected for. Event 2-digit event tag representing a discreet leg or time period of fieldwork.
