Street Centerlines

** The Street Centerline feature class now follows the
NG911/State of Illinois data specifications including a StreetNameAlias table.
The download hyperlink above also contains a full network topology for use with
the Esri Network Analyst extension **
These street centerlines were developed for a myriad of uses
including E-911, as a cartographic base, and for use in spatial analysis.
This coverage should include all public and selected private
roads within Lake County, Illinois. Roads are initially entered using recorded
documents and then later adjusted using current aerial photography. This
dataset should satisfy National Map Accuracy Standards for a 1:1200 product.
These centerlines have been provided to the United States
Census Bureau and were used to conflate the TIGER road
features for Lake County. The Census Bureau evaluated these centerlines and,
based on field survey of 109 intersections, determined that there is a 95%
confidence level that the coordinate positions in the centerline dataset fall
within 1.9 meters of their true ground position.
The fields PRE_DIR, ST_NAME, ST_TYPE and SUF_DIR are formatted
according to United States Postal Service standards.
Update Frequency:
This dataset is updated on a weekly basis.
