SpecAddr
Special Address Type Code
a
Alternate Address Range: Alternative address ranges for the same street name. This can occur where buildings have been renumbered; old numbers will sometimes remain in use. For example, such usage is common in some Queens neighborhoods, including Far Rockaway, Douglaston, Forest Hills and Ridgewood, where non-hyphenated addresses have been replaced by hyphenated addresses.
b
Alternate Street Names: Alternate street names that cannot be handled in the usual way.
c
Handles a unique situation along the Brooklyn-Queens border, where Ruby Street on the Brooklyn side of the street is known as 75 Street in Queens. Some Brooklyn residents use 75 Street in their address; however there is another 75 Street in the Bay Ridge section of Brooklyn, far from the Queens border.
d
Duplicate Addresses: Duplicate addresses for the same street name. This is primarily restricted to two situations: 1. Hillside Avenue in Queens- there are two Hillside Avenues, one in Far Rockaway, another in Douglaston; and 2. Dr. Martin Luther King, Jr. Blvd. in Manhattan. This street name is an alternative name for both E 125 St. and W 125 St. As a result, there are numerous duplicate addresses along this street.
e
Refers to situations in which the name of a neighborhood can serve as an alternate name for all streets in that neighborhood. The two neighborhoods for which this applies are both in the Bronx: Edgewater Park and Harding Park.
g
This is used for names of complexes (e.g., Lincoln Center). Complexes are non-addressable, and are composed of a number of non-addressable place names. Complexes can include individual buildings or parks that are recognized as a grouped entity (e.g., Lincoln Center, Jefferson Houses, City College). "G" records refer to the complex names (Lincoln Center), while the entities within the complex (Alice Tully Hall, Metropolitan Opera, etc.) are flagged as type "x" records. Because of restrictions imposed by MapInfo's address matching, the user must include a "0" as a house number to successfully match a non-addressable place name. For example, "0 Lincoln Center" will match to the correct side of the street for that location.
n
Non-Addressable Place Name: This is used for non-addressable place names. These are place names that cannot be combined with a house number to form an address. Such place names can include individual buildings (e.g., City Hall, Alice Tully Hall), building complexes (e.g., Columbia University, New York Hospital) and large facilities (e.g., Penn Station, LaGuardia Airport). Because of restrictions imposed by MapInfo's address matching, the user must include a "0" as a house number to successfully match a non-addressable plance name. For example, "0 City Hall" will match to the correct side of the street for that location.
p
This is used for out-of-sequence addresses. Such addresses do not follow the logical addressing sequence of the immediately adjacent buildings. For example, address number 62 of a street may exist between addresses 80 and 82, not between 60 and 64 on that blockface (it may also appear on a blockface other than that which contains 60 and 64). Also, the address may be an opposite-parity address, in that its parity (odd/even) is the opposite of the predominant parity on the blockface. For example, address number 62 may appear on the odd side of the street between 63 and 65.
s
This refers to situations in which the break in addresses from one block face to the next along a street involves house number suffixes. These suffix addresses are not included in MapInfo LION. The "s" flag appears with such records to denote that a suffix exists at either the low or high end of the segment's address range.
v
This is used for "vanity addresses" (i.e. addresses in which the street name refers to a different street than the one on which the referenced building entrance is actually located). For example, 1049 5th Avenue in Manhattan, a vanity address, is actually located on East 86th Street, between 5th Avenue and Madison Avenue.
x
This is used for names of non-addressable parts of complexes (not the entire complex name itself, which is flagged as type "g"). These are non-addressable place names grouped with other non-addressable place names to form a larger, non-addressable complex. Such non-addressable place name parts of complexes can include individual buildings or parks (e.g., Alice Tully Hall of Lincoln Center, Damrosch Park of Lincoln Center, Jefferson Houses Building 2 of Jefferson Houses, Shepard Hall of City College). Because of restrictions imposed by MapInfo's address matching, the user must include a "0" as a house number to successfully match a non-addressable place name. For example, "0 Alice Tully Hall" will match to the correct side of the street for that location.
FaceCode
A four digit number assigned to any linear geographic feature in LION. This can be either a street or non-street feature (e.g., shoreline railroad tracks).
SeqNum
A five digit number assigned sequentially to the street segments within a given face code. The sequence number generally increases with the direction of the street.
StreetCode
Boro 5-Digit Street Code
LGC1
Local Group Code 1: A Local Group Code (LGC) is a qualifier for DCP's 5 digit street code. Each LGC value represents a group of names for the given street that are valid for that segment.
LGC2
Local Group Code 2: A Local Group Code (LGC) is a qualifier for DCP's 5 digit street code. Each LGC value represents a group of names for the given street that are valid for that segment.
LGC3
Local Group Code 3: A Local Group Code (LGC) is a qualifier for DCP's 5 digit street code. Each LGC value represents a group of names for the given street that are valid for that segment.
LGC4
Local Group Code 4: A Local Group Code (LGC) is a qualifier for DCP's 5 digit street code. Each LGC value represents a group of names for the given street that are valid for that segment.
BOE_LGC
Board of Elections LGC Pointer (Domain values = 1, 2, 3, 4) indicates which LGC field (LGC1, LGC2, LGC3 or LGC4 respectively) corresponds to the name for this segment that is used for Board of Elections applications.
SegmentID
A number of up to seven digits that identifies each segment of a street or a non-street feature represented in the LION file. Segment-ID differs from the LION Key in that the former identifies a segment, a geographic entity, whereas the latter identifies a record in the LION file. In the case of a segment lying along a borough boundary, say one that lies along the Brooklyn-Queens border, both the Brooklyn and Queens DCPLION files will have a record representing that segment; the LION Keys of those two records are distinct, but the Segment-ID's are identical.
SegCount
Coincident Segment Count indicates situations where there are double-decker roads and therefore more than one segment for the same geography in LION. An example would be the upper and lower roadways of the George Washington Bridge. In this case, the SegCount would be = 2. Most LION segments will have a SegCount of 1.

'Minimal' means the polygon is not subdivided by LION segments (other than the noted exceptions) into smaller polygons. A dynamic block can contain segments of various types in its interior: paper street segments (Feature Type = 5), dead end segments (LocStatus = I), land-hooked segments (LocStatus = H) and alley segments (Feature Type = A). Dynamic block numbers are unique within 2000 Census Tracts and are used as building blocks for many higher geographies.

SanDistInd
Sanitation District Indicator. Normally, sanitation routes are defined by the community district (CD) and sanitation district subsection. For some streets that divide a CD, the same route will service both sides. This indicator defines which CD will service the entire street. The Subsection (LSubSect and RSubSect) is NOT affected by the sanitation district indicator.
L
Left: For both sides of the street, the sanitation district is defined using the CD on the left side of the street.
R
Right: For both sides of the street, the sanitation district is defined using the CD on the right side of the street.

MapTo
DCP Sectional / Zoning Map at the end of the segment.
NearBQ
Near Brooklyn/Queens. Indicates segments that are within 1.7 miles of the Brooklyn-Queens boundary for special processing done for the Department of Education.
BoroBndry
Borough Boundary Indicator. When a segment lies along a boundary of two boroughs, it is represented by two separate LION records, one for each borough. The flag indicates which side of the segment is out of the borough.
MH_RI_Flag
Marble Hill/Rikers Island Flag. These are two areas of the city that legally are part of one borough, but serviced by another. In each case, these records are flagged to be generated by the alternative borough for Geosupport purposes.

ConParity
Continuous Parity Indicator (Domain Values = L, R). A continuous parity segment has both odd and even addresses on the same side of the segment, and no addresses on the other side. In a LION record that represents a continous parity segment, the odd and even address ranges are stored separately and the 1-byte code indicates on which side of the street the addresses physically exist.
L
Odd and Even house number are bothe on the left side of the segment.
R
Odd and Even house number are bothe on the right side of the segment.
Twisted
Twisted Parity
T
Indicates that the address parities along a street have swithced since the immediately preceding segment of the same street (i.e., if odd addresses were on the left, they are now on the right).
LLo_Hyphen
Low Value for the hyphanated address range beginning on the left side of the street segment. Left and right are defined relative to a street segment's direction. For streets that have addresses, the direction of a DCPLION streeet segment is determined by the direction of increasing address numbers. Note that this direction is unrelated to the street's traffic direction or its orientation relative to the points of the compass. The direction of streets with out address numbers, as well as non-street features, is assigned arbitrarily, but is consistent within the street feature. Direction can usually be determined by observing which way the SeqNum increases. Includes hyphanated addresses.
LHi_Hyphen
High Value for the hyphanated address range beginning on the left side of the street segment.
FromRight
Low Value for the numeric address range beginning on the right side of the street segment.
