(AREA, PERIMETER, PARCEL#, and PARCEL-ID are required fields in Arc/Info.)

LINK-ID - Unique polygon identifier to relate to tabular database.

SCHED_NO - Parcel identifier assigned by the Treasurer.

STATEPID - This number is the combination of the four-digit State Township/Range number, two-digit section number, one-digit quartersection number, two-digit assigned block number, three-digit assigned lot number. This 12-digit number is obtained by combining ST_CODE, SECTION, AQSECT, ABLOCK, and ALOT.

PARCELNO - Larimer County Tax Assessor parcel number which combines the Assessor range/township, section number, assigned quarter-section number, assigned block, assigned lot.

SECTION - Two-digit number ranging from 1 to 36 defining approximately one square mile as established by the PLSS.

AQSECT - Assigned one-digit number ranging from 1 to four describing approximately one-fourth of a section as established by the PLSS. Values are delineated as follows:

0 - full section

1 - northeast quadrant

2 - northwest quadrant

3 - southwest quadrant

4 - southeast quadrant

ABLOCK - Assigned Block Number assigned by the Tax Assessor and used as part of the parcel identification number.ALOT - Assigned Lot Number assigned by the Tax Assessor and used as part of the parcel identification number.
