Description:
Abstract: Road Centerlines for Tompkins County.
Purpose: The road centerlines serve as a base map for streets and addresses.
Supplemental_Information: This data set was derived from the 1991 Tompkins County Planimetric Base Map and updated using field work, aerial photography, the Local Highway Inventory, paper maps, the tax parcel data sets, and digital orthophotos. The roads were joined to the Address.dbf database and several fields were dropped from the original in Fall of 2004 when it was transferred to an ESRI personal geodatabase. For map display purposes, do not show abandoned/proposed roads or roads with restricted access. This can be accomplished by using a filter of ([Access] < 5).

Data_Quality_Information

Attribute_Accuracy:
Attribute_Accuracy_Report: See Entity and Attribute Information
Logical_Consistency_Report: Spatial topology is maintained by the software's robust geometric network topology tools and manually by ensuring that each road intersection forms a node. Additional nodes are created at intersections with major hydrologic features, municipal boundaries, road surface changes, route type changes, and abrupt changes in addressing. The ROADID field is checked using a "frequency" command to ensure there are no non-unique values. The entire data set was reviewed on paper maps by each municipality in 1998.
Completeness_Report: Complete for Tompkins County. There is some overlap into adjoining counties.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Varies, depending on source of centerline (Planimetric Base Map, digital tax maps, aerial photo, raw conversion from paper maps, etc). The accuracy of the data set is limited to the accuracy of the 1991 Tompkins County Planimetric Base Map series.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: The Accuracy of the data set is limited to the accuracy of the 1991 Tompkins County Planimetric Base Map series.
Lineage:
Process_Step:
Process_Description: Before 2004, address ranges were being maintained in a separate database named TCAddresses.dbf. and exist in two forms. The first consisted of the Address ranges that were used in ArcView and similar GIS packages that only support a one-to-one relationship between street segments and addresses. The addresses of this first form are sorted in ascending order on the field sortorder so that the most appropriate (current) records will be "joined" in the GIS (ArcView "joins" the first record, then ignores all subsequent records). The second form of addresses includes all the address records that may exist for a particular link. For example, Elmira Road will have a duplicate record with a street name of State Route 13 (and the same addresses, if Route 13 is a valid Post Office name). For roads and addresses that exist in more than one zipcode, records with the appropriate address ranges will exist for each zipcode. Address ranges were assigned based on the digital tax parcel maps and fieldwork. Where houses did not exist near intersections (with streets, railroads, streams, municiapal boundaries, etc), address ranges were calculated proportionally based on the nearest two addresses and the distance between them. Specifically, the total distance between known addresses was divided by the address range difference to determine the distance-per-address. The length of each segment from the known address to the intersection was then divided by the distance-per-address to determine the ending and beginning ranges on either side of the intersection The TCAddressses.dbf table was joined to the roadcl featureclass in Fall of 2004. The addresses were filtered first by sortorder=1 then exported to a separate table, addr_sort.dbf . This database was joined to the roadcl feature class. Thus, the address values of TCAddresses database is now part of the road centerline featureclass. The database is no longer used since address ranges are added and edited directly one the roadcl line features. There were several roads that did not get an address range due to duplicate "roadids." A frequency script was used on the 'roadid" field and it was discovered that the vlaues of the roadid field was not unique. These road segments were manually located and fixed. The frequency script should be executed after each major update to check that these ids are unique in the future. **There is a need to change the scheme for assigning unique ids to the roadcl feature class so that it is less complicated than the format below and more apparent to other municipalities. These ideas were discussed in brief but not extensively and no decisions were made so the procedures for assigning ids to the roadid field continues. SEE ENCLOSURE FOR THE PROCEDURE FOR ASIGNING VALUES TO THE ROADID FIELD.

Attributes:
Name Description Values
OBJECTID Internal feature number. Sequential unique whole numbers that are automatically generated.
FNODE_ Arc's from-node record number (Internal Software Attribute)
TNODE_ Arc's to-node record number (Internal Software Attribute)
ROADID Unique road segement identifier. For more information, consult the Process Information under the Data Quality Section of this metadata
NAME Full commonly-used name of the road, which may or may not be the deeded name, post office name, etc.
ALTNAME Alternate, post office, tax parcel map, deeded, or local full name of the road.
ROUTETYPE Type of touring route. coded values
MAINTNANCE Primary party responsible for maintaining the road (not complete) coded values
ROUTE Federal, State, County, or Town touring route number. For multiple-routes, use a forward slash (/) between the numbers, such as 13/34.
ACCESS Type of access to the road. coded values
HISTRCNAME Previous or historical name of the road.
HISTRCRTE Previous or historic route number, including ownership, which should come first and be followed by a dash (example: 2-392 would mean an historic route of state road 392). Multiple historic routes can be listed seperated by commas.
NODEA The name of the cross street, dead end, hydrologic feature, municipal boundary, or other feature that defines the beginning of the road segment. The terms "left" and "right" are relative to viewing the road segment from beginning node (NODEA) to ending node (NODEB)
NODEB The name of the cross street, dead end, hydrologic feature, municipal boundary, or other feature that defines the end of the road segment. The terms "left" and "right" are relative to viewing the road segment from beginning node (NODEA) to ending node (NODEB).
DIRECTION Determines whether the street is one-way or bi-directional. coded values
PTYPE Pavement Type. coded values
SORTORDER Sorting order for use in ArcView and other GIS software packages that do not support many-to-one relationships for geocoding. This database must be sorted first on ROADID, then on SORTORDER for a proper relationship between it and the ROADCL data set to be established. Those address records that are most recent or most likely to represent the majority of real-world address occurences for a particular street segment are given a sort order of 1. Additional address records for the same street segment are given higher SORTORDER numbers, with the highest numbers representing the least-used real-world addresses.
PREFIXDIR Street prefix direction. coded values
STREETNAME Post office, deeded, or local street name.
STREETYPE Street type (avenue, street, road, lane, way, circle, etc.) coded values
SUFFIXDIR Street suffix direction. coded values
SORTNAME Street name that is used for sorting purposes. Prefix directions are placed last or are spelled out if they refer to places rather than direction. For example, N Cayuga Street would have a sort name of Cayuga Street N, while W Danby Rd would have a sort name of West Danby Road because West Danby is a place, not a direction.
MUNICIPLTY Municipality in which the address is located. Please note that roads that form a municipal boundary may have different names and/or addresses in each municipality. The municipality name is spelled out (eg: TOWN OF CAROLINE).
SHAPE_Leng Length of feature in internal units. Positive real numbers that are automatically generated.
UPDATED Date that the record in the GDB was last updated (User Specified).
DISPLAY Visual display of roads representing a combination of their access, routetype, and ptype, used primarily for Taxmap index and major road display. coded values
