The Nebraska Highway Network is a digital representation of all motor vehicle transportation routes in the State of Nebraska, for which the Nebraska Department of Roads has responsibility of management and maintenance.
The Nebraska Highway Network was developed to provide a digital coverage of the state-maintained roads system for planning applications.
Background information, such as state, county, and municipal boundaries provide a reference layer for the Nebraska Highway Network.

All routes in the state highway network are verified by checking attribute data with the construction plans developed for each route project
All vector linework in the state highway network has been cleaned using Intergraph's Line Cleaner command, resulting in a topologically correct coverage
All attributes for each route within the state highway network were verified using the Integrated Highway Inventory database
Coverage accuracy is consistent with U.S.G.S. 7.5 minute quadrangle sheets for associated areas
Vertical accuracy is not a consideration for this coverage
Spatial and attribute information
The data set for the state highway network was processed using the following steps: 1) Each route in the network was digitized from U.S.G.S. 7.5 minute topographic quadrangle and Digital Line Graph sources, using a CADD system. The digitized route graphics were then placed into Intergraph's MGE format, and checked against the corresponding construction plans and survey records to verify accuracy. 2) Within MGE, the route graphics were incorporated as elements into a design file, which allows attribute linkage to relational database records. A universe list file was then built from the design file to serve as a reference for information about the attribute linkage of the elements. After the universe list file was built, it was analyzed to ensure that the attribute linkage information was correct, and that all graphic elements in the design file were accounted for. Once this was done, the graphical linework was cleaned and edited to confirm topological accuracy. Following graphical cleanup, a feature table was created for the purpose of integrating graphic elements, as state highway features, along with associated database tables, which store all attribute information about the features. 3) A universe list file was built from the state highway features table to serve as a reference for the attribute linkage information of the state highway feature graphics. The feature graphics were then processed to generate and validate a dynamic segmentation control network consisting of the beginning and ending control points for each route feature. 4) The coordinates of the beginning and ending control points were placed into a control point data base using a customized shell script. Information from the Integrated Highway Inventory data base was used to create coordinates for intermediate control points found within each route. These coordinates were also added to the control point data base. 5) The universe list file was re-built to reflect changes to the state highway features and the addition of control points. After re-building, it was re-analyzed to be sure that all features and points were updated correctly. 6) The features and points were then modified, as needed, to accurately reflect graphical representation. After graphical modification, the universe list file was re-built and re-analyzed to account for all features and points. A final generation and validation process was run to produce a completed dynamic segmentation control network of linear features and control points with attribute linkage for the state highway network.
