Description:
Abstract:
The Traffic Signals layer was collected as part of the
Clinton County,OH Road Centerline and Address Mapping
Project. This layer contains a point-based geometry. Each
point represents a single traffic signal.
Purpose:
The Traffic Signals layer was collected as a supplemental
layer for the Clinton County,OH Road Centerline and
Address Mapping Project. Traffic control may assist in the
routing of emergency vehicles. Also this layer supplies the
county with the locations of their traffic signals.
Supplemental_Information:
The Traffic Signals layer does not represent the exact
locations of the traffic signals. The layer is meant to
show the traffic control for a particular leg of the intersection.

DATA_QUALITY_INFORMATION
Attribute_Accuracy:
Attribute_Accuracy_Report:
The distance from the centerline for all points generated
in the Traffic Signal layer was examined. If the distance
exceeded 1.5 meters, it was determined if the point was
still in the right of way using the ortho photo.
Logical_Consistency_Report:
Intersections were checked for duplicate traffic signal points.
Completeness_Report:
All visible traffic signals were collected. The
completeness of collection is not guaranteed.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal position is in the right of way as compared
to the centerlines and ortho photos.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical position is the height of where the point was
collected, not the actual height of the traffic signal.

Process_Description:
In the field, raw GPS for the traffic signal is collected
in the roadway just before entering the intersection. The
raw data is brought back to DDTI to be processed. A point
shape file is generated for all traffic signal collected.
The shape file is checked for errors. Finally, the file is
prepped for delivery.

Disclaimers of Liability
DISCLAIMER OF WARRANTIES AND LIMITATION OF LIABILITY
Digital
Data Technologies, Inc. (DDTI) has provided to Clinton County,OH
Geographical Information Systems (GIS)
Basemapping and Data Integration services, the product of
which have been recorded in formats for uses that include
display on a Web site, by the County at is employee's work
stations, and for distribution to the public (referred to
as "Products"). While DDTI has made warranties to the
County that the data it obtained were collected in a
workmanlike manner using accepted industry procedures, it
cannot guaranty 100% accuracy of the data and Products
since two of the three major inputs to the mapping process
require DDTI's dependence on the accuracy of information
and technology over which DDTI has no control. Further, any
data conversion performed by DDTI for the County to produce
Products are subject to the same two input issues. These
two inputs over which DDTI has no control are data obtained
from satellite-controlled positioning and data that the
County has provided to DDTI from public records maintained
by the County and organizations other than DDTI. This
Disclaimer does not mean that the final product is faulty,
but simply that DDTI cannot warrant the accuracy of the
Products containing the final data, which are an
integration of its collected data, the satellite-controlled
positioning data, and the information given to DDTI by the
County. THEREFORE,
DDTI PROVIDES THE DATA TO THIRD PARTY USERS OF THE DATA ON
AN "AS IS" BASIS. DDTI MAKES NO REPRESENTATIONS OR
WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, AS TO THE
ACCURACY OF THE DATA AND YOU AGREE BY YOUR USE OF THIS DATA
THAT SUCH USE IS AT YOUR SOLE RISK. TO

DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING,

THE LAW, DDTI WILL NOT BE LIABLE FOR ANY DAMAGES OF ANY
KIND ARISING FROM THE USE OF THE DATA AND PRODUCTS,
INCLUDING, BUT NOT LIMITED TO DIRECT, INDIRECT, INCIDENTAL,
PUNITIVE, AND CONSEQUENTIAL DAMAGES, ABSENT ITS GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT. CERTAIN
STATE LAWS DO NOT ALLOW LIMITATIONS ON IMPLIED WARRANTIES
OR THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IF THESE
LAWS APPLY TO YOU, SOME OR ALL OF THE ABOVE DISCLAIMERS,
EXCLUSIONS, OR LIMITATIONS MAY NOT APPLY TO YOU, AND YOU
MIGHT HAVE ADDITIONAL RIGHTS. BUT YOU AGREE THAT THE ABOVE
SHALL APPLY TO YOUR USE OF THE DATA AND PRODUCTS TO THE
FULL EXTENT OF APPLICABLE LAW.
