GRANIT CONSERVATION/PUBLIC LANDS LAYER
MAPPING AND AUTOMATION STANDARDS
Revised January, 2001
Revised April, 2001
Revised April, 2002
Revised September, 2002
Revised May, 2003

The GRANIT Conservation/Public Lands Layer contains a digital record of parcels of land of two or more acres that are mostly undeveloped and are protected from future development.  Smaller parcels that adjoin previously mapped parcels or represent unique features, such as a bog or state-owned boat ramp, may also be included in the data layer.  

Each parcel may comprise one or more tracts and thus may be represented by one or more features (polygons) in the spatial database.  Multiple tracts may occur as a result of multiple acquisitions over time, single acquisitions from multiple owners, and/or a parcel that is bisected by a road or other base feature.   

The data is archived in ARC/INFO as a combined polygon/line coverage and an associated data file (ADF file).  The polygon coding contains a Tract ID, or TID, which provides the linkage to the remaining polygon attributes archived in the ADF.    The line coding is maintained to reflect the source/scale of the individual tract boundaries, and to indicate coincidence with other GRANIT features.
SECTION I.  POLYGON  CODING STANDARDS 

The polygon coding standards are presented in  two parts.  Part  A provides the data dictionary for the polygon coding in the polygon attribute table,  or PAT.  Part B provides the balance of the polygon coding information, which is resident in the associated data file, or ADF.  

A.  Polygon Codes in the PAT

1.  	TID - Tract Identifier (13,13,C):  (Columns 11-13 will be blank for existing tracts.)

	Columns 1-3 		3-digit GRANIT Quad ID
	Column 4 		Hyphen
	Columns 5-7		3-digit Parcel ID (sequentially assigned)
	Columns 8-9		Reserved for retention of legacy alphanumeric designations.  Should not 
				be populated for any new tracts.
	Column 10		Hyphen
	Columns 11-13	3-digit Tract ID (sequentially assigned)

	Use 999-99999-999 to signify outlots.

B.  Codes in Associated Data File

1.  	TID - Tract Identifier (13,13,C):  (Columns 11-13 will be blank for existing tracts.)

	Columns 1-3 		3-digit GRANIT Quad ID
	Column 4 		Hyphen
	Columns 5-7		3-digit Parcel ID (sequentially assigned)
	Columns 8-9		Reserved for retention of legacy alphanumeric designations.  Should not
				be populated for any new tracts.
	Column 10		Hyphen
	Columns 11-13	3-digit Tract ID (sequentially assigned)

2.  	NAME - Tract Name (42,42,C):  (enter in upper/lower case)

	Tract name as known by the protecting entity.

3.  	NAMEALT - Alternate Tract Name (42,42,C): (enter in upper/lower case)

	Tract name as originally reported during data collection/automation, if different from NAME.

4.  	P_NAME - Parcel Name (42,42,C):  (enter in upper/lower case)

	Parcel name as known by protecting entity.

5.  	P_NAMEALT - Alternate Parcel Name (42,42,C):  (enter in upper/lower case)

	Parcel name as originally reported during data collection/automation, if different from PNAME.

6.	PPTYPE - Primary Protection Type (2,2,C):  (enter in upper case)

AR	Agricultural Preservation Restriction *
CE	Conservation Easement *
DR	Deed Restriction *
FE	Flowage Rights or Easement (formerly FL) *
FO	Fee Ownership (formerly FR)
HP	Historic Preservation Easement
LE	Longterm Lease
PE	Protective Easement (for Water Supply Lands)
RV	Reverter
RW	Right of Way
SA	"Set Aside" Open Space Areas of Developments *
SE	Scenic Easement

* Land protected by these methods is typically private property and is not open for public access.  Terms of these conservation restrictions vary considerably;  consult deeds for specifics.

7.	PPTERMTYPE - Term of Protection (1,1,C):

	P	Perpetual
	L	Limited term
	U	Unknown

8.	PPTERM - Length of Limited Protection Term (3,3,I):

	-98	N/A - term is perpetual
	-99	Unknown
	nn	Length in years of limited term

9-10.	SPTYPE1, SPTYPE2 - Secondary Protection Types 1 and 2 (2,2,C): (enter in upper case)	
  
This is a "back-up" or second method of protection applied to a parcel that already has a primary protection method.  It includes those types    listed below in addition to all primary protection types:

EI	Executory Interest
LE 	Lease

11.	PPAGENCY - Primary Protecting Agency/Organization (5,5,I):

Agency or organization responsible for protection of the parcel from development.  When more than one agency/organization is involved, the distinction between primary and secondary protecting agency/organization is sometimes arbitrary.   Most often, the primary protecting entity is the one that actively manages the property or owns the land.  The agencies should be contacted for more specific property information.

Town/Cty:	5-digit FIPS code (additional information describing the specific entity that 					
	manages the property may be entered in the notes fields, e.g. conservation 			
	commission, water department, etc.)

12.	PPAGENTYPE  - Type of Primary Protecting Agency (1,1,I):

	Generalized version of PPAGENCY codes, as follows:

	1	Municipal/County
	2	Federal
	3	State
	4	Other Public/Quasi-Public Entity
	5	Private

13-14.	SPAGENCY1, SPAGENCY2 - Secondary Protection Agencies 1 and 2 (5,5,I):

Same as primary protection agency codes (item 12), plus the following:

52900  GRANTOR
	(Grantor is not an agency or organization.  Grantor restrictions or
	reverters add additional protection to a property.)

15.	RSIZE - Reported Size  of Tract (8,8,N,1):

Acreage as reported on the source document.  Value of -999 indicates no size was 
indicated on the source.

16.	CSIZE - Calculated Size  of Tract (8,8,N,1):

Acreage as calculated based on the automated parcel boundaries.  This acreage typically differs from RSIZE (see above).

17.	   P_RSIZE – Reported Size of Parcel (8,8,N,1):

Acreage as reported on the source document. This acreage is the sum of the reported 
tract sizes (RSIZE). Value of –999 indicates no size was indicated on the source.

18.          P_CSIZE – Calculated Size of Parcel (8,8,N,1)
         
         Acreage as calculated based on the automated parcel boundaries. This acreage is the sum of 
         the calculated tract sizes (CSIZE).

19.	PROGRAM (2,2,I):

Program or agency under whose auspices the protection took place:

0	No acquisition program noted
1	Land Conservation Investment Program
2	Agriculture Preservation Restoration
3	Land & Water Conservation Fund
4	Appalachian Trail
5	Highway Beautification Project
6	NRCS Flood Control Project
7	US Forest Service Forest Legacy Program

20. 	LEVEL - Protection Level (2,2,C):

1	Permanent conservation land.  Land protected from development through
conservation easement, restrictions, or outright ownership by an
organization or agency whose mission includes protecting land in
perpetuity;  more than 50% of area will remain undeveloped.
2	Unofficial conservation land.  Land owned by an agency or organization whose 
mission is not conservation, but whose intent is to keep the land for
conservation, passive recreation, or educational purposes.  
Not permanently protected.
2A	Water supply lands.  Lands owned or controlled by suppliers of public
drinking water.  Includes all supplies owned by a municipality or a 
subdivision of a municipality, and all private water systems that serve 500
people or more.
3	Unprotected public open space land.
4	Developed public land.  Includes lands having active recreational use on 
more than 50% of the area, e.g. beaches, picnic areas.
9          Unknown

21.	MSTATUS  - Management Status (1,1,I):

	1	A tract totally protected from conversion of natural land cover and with a
		management plan or deed in operation to maintain land in a natural state.  Natural
		processes are allowed to proceed without interference or are mimicked through
		management practices.
	2	A tract totally protected from conversion of natural land cover and with a
		management plan or deed in operation to maintain a primarily natural state, but where
		uses (e.g. vehicular traffic, hunting, etc.) and/or suppression of natural processes
		may degrade the quality of existing natural communities.
	3	A tract protected from conversion of natural cover for more than 50% of area,
		but subject to extractive uses such as timber harvest or mining.
	4	A tract with more than 50% of area unprotected from conversion of natural cover
		or planned or in use for agriculture or as "open space" for active recreation
		purposes (e.g. ballfields, golf courses).  Natural processes are altered or replaced
		by human use and management of land.
	9	Unknown

22.	SOURCE (25,25,C): (enter in upper case)

Source of information used for mapping the tract.  While individual tract boundaries may be mapped from different sources as captured in the line coding (e.g. in the AAT SOURCE field), this field reports the initial source used to map the tract.  This data is used to establish the ACCURACY rating.  

23.	ACCURACY (1,1,I):

General flag used to indicate the accuracy of the parcel boundary mapping.
1	Very good. Mapped from a survey which aligned well with existing 
information.
2	Good.  Mapped from a good quality tax map or from a survey which did
not completely align with existing information.
3	Fair.  Mapped from poor tax map, survey, or other source.  Some lines
are questionable.
4	Poor.  Mapped from a source which had obvious problems with spatial
accuracy.  Location and/or configuration are approximate only.
5	Unknown location and configuration.  General area may be known.  (Used 
only for saltmarsh lots.)

24.	COBKPG - County, Book and Page (40,40,C):

County Registry of Deeds book and page reference number to legal transaction record.   Deeds are often the source of information about the nature of restrictions on restricted properties.
Space is provided for multiple deeds/instruments.

While the field is defined as a long character, the format of data entries is as follows:

Columns 1-2:		2-digit county FIPS code
Column 3:		/
Columns 4-6:		3-digit book number
Column 7:		/
Columns 8-10:		3-digit page number

If there are multiple entries, the second (and subsequent) references are entered
as:

Column 11:		blank
Column 12:		+
Column 13:		blank
Columns 14-23:	Same as Columns 1-10 above

25.	DATEREC1 (8,8,C):

	Date of  record for first conservation transaction 

26.	DATEREC2 (8,8,C):
	
	Date of record for second conservation transaction 

	If there are more than two transactions associated with the tract, the remaining dates of record	
	are entered in the NOTES fields.

27.	ACCESS  - Level of Public Access (1,1,I):

1	Allowed (Minor use restrictions may apply, such as fees charged, vehicular access, etc.)
2	Restricted to Certain Areas  (Access restricted to specific areas or times, or member/
	resident use only.)
3	Not allowed
4	Unknown
5	No response to access survey received 

28.	DATEADDED (8,8,C):

	Date record (spatial/attribute) was added to the database.  While all of a tract's boundaries
	may be replaced over time, this field will still reflect the date the original tract polygon was
	created and the attributes were added.

29.	  DATEALTER (8,8,C):

	 Date of last revision of any of the tract boundaries or attributes.

30.	NOTES1 (80,80,C): (enter in upper case)

Additional notes field 1. 

31-32. 	NOTES2, NOTES3, NOTES4 (80,80,C): (enter in upper case)

Additional notes field 2, 3, and 4.

SECTION II.  ARC CODING STANDARDS 

The line representation of the Conservation/Public Lands Layer is used in creating, managing, and maintaining the data layer.  The codes are used to a) reflect coincidence of tract boundaries with other elements archived in the GRANIT database, or b) retain other information specific to a tract boundary (e.g. source).

1.  	LID (4,4,I):   

Line ID to identify coincidence with other features.

1	Arc is a parcel boundary that is coincident with a political boundary
2	Arc is a parcel boundary that is coincident with a  road centerline
3	Arc is a parcel boundary that is coincident with a pipeline/transmission line
4	Arc is a parcel boundary that is coincident with a surface water feature
5	Arc is a parcel boundary that is coincident with a railroad
6	(Not assigned)
7	Arc is a parcel boundary that is coincident with another parcel boundary
98	Arc is a parcel boundary and its location is uncertain or poorly defined
99	Arc is a parcel boundary that is not coincident with other features

	9999 	Arc is a closure line created at the state boundary, but does not represent a parcel 
		boundary

2.  	SOURCE (4,4,C):   

	Source of the tract boundary:

	DLG	Digital Line Graph data.
	DOT	DOT road centerline data
	DXF	Autocad DXF file
	GPS	Source of polygon boundary is GPS data.
	E911	Enhanced-911 data
	SUR    Survey 
            TAX    Tax map 

3.  	DATEADDED (8,8,D): 

	Date tract boundary was added to the database. 

4.	DATEUPDATED (8,8,D): 

	Date of last revision to tract boundary.
