Segment Properties

Segment properties specify the location and attributes of a segment. Some attributes have direct values (for example, address ranges, one way designations) while some are identifier links.

To view the Segment properties, click Map > Properties . The Properties dialog appears.

The following table lists and describes properties in the Name column:
Segment Property Description
segID System-generated segment identifier.
namID

System-generated name identifier. This identifier links segments to name information. To view/edit the name properties for the selected segment, click the arrow to activate it.
source Internal code reserved for Trapeze use.
oneWay
Internal code identifying a one-way street segment. Valid values are:
  • (blank) - Two way street
  • > - One way street from - to point
  • < - One way street to - from point
  • * - Blocked both ways
CFCC

Classification code that describes segments such as arterial, water or rail. To view the classification code for the selected segments, use the list. The segment types will be displayed. To select a code, double-click the segment type desired.

Census Feature Class Codes (CFCC) determine the type of the road (for example, interstate, residential, collector) and other segments (for example, water, railways). Trapeze4 codes are compatible with TIGER/Line format; therefore, these codes can be typed in manually. For convenience, a drop-down list with commonly used CFCC types is provided.
frAddrL Address number closest to the start of the segment (from point) on the left side of the road.
toAddrL Address number closest to the end of the segment (to point) on the left side of the road.
frAddrR Address number closest to the start of the segment (from point) on the right side of the road.
toAddrR Address number closest to the end of the segment (to point) on the right side of the road.
zipIdL

Zip code for the left side of the road. Zip codes can be selected from the supplied drop-down list of the existing ones or can manually typed.

If numeric ZIP codes (U.S.) are used, this field is the direct value.
zipIdR

Zip code for the right side of the road. Zip codes can be selected from the supplied drop-down list of the existing ones or manually typed.

State and place code for the left side of the road. statePlace is a numeric code in the following format:

SSPPPPP, or stateCode * 100000 + placeCode

Where:

  • SS is a two-digit state code
  • PPPPP is a five-digit place (city) code

The text value giving the actual name and abbreviation corresponding to the codes can be found in the mapPLC table:

  • For the state, in a row whose plcType has value of 1 and whose state column has the value of stateCode (these codes are mainly used only in U.S.)
  • For the place, in a row whose plcType has value of 55, and whose value for plcCode column has the value of statePlace.
statePlaceR State and place code for the right side of the road.
countyMcdL

Displays the county and minor civil division code for the left side of the road.

countyMcd is the numeric code that comprises of:

  • Three digits representing county code, and
  • Five digits representing Minor Civil Division (MCD) code

in the format: CCCMMMMM, or countyCode * 100000 + McdCode

The text value giving the actual name and abbreviation corresponding to the codes can be found in mapPLC table. For the county, in a row whose plcType has value of 6, whose value for plcCode column has the value of countyCode, and whose state column has the value of stateCode for the same segment (this information is included for the sake of completeness only, and is not utilized in the software).

For the MCD, in a row whose plcType has value of 44, and whose value for plcCode column has the value of countyMcd.
countyMcdR

Displays the county and minor civil division code for the right side of the road.

The countyMcd is the numeric code that comprises of:

  • Three digits representing county code, and
  • Five digits representing Minor Civil Division (MCD) code

For the county, in a row whose plcType has value of 6, whose value for plcCode column has the value of countyCode, and whose state column has the value of stateCode for the same segment (this information is included for the sake of completeness only, and is not utilized in the software).

For the MCD, in a row whose plcType has value of 44, and whose value for plcCode column has the value of countyMcd.
