ABSTRACT: The area with the fastest growing
Native American population in North Dakota is the Fort Berthold Reservation.
State and federal road information available to the public is not identical in
terms of the number of physical road segments or in the attribute information
provided for the road network. In this study we develop: 1) a navigable road
network achieved by improving connectivity among road segments, updating road
information, and making a comprehensive network; and 2) a standard process for
integrating the state and federal local road information. The standard process
broadly consists of three Parts: 1) combining road segments from each source; 2)
providing legitimacy to snapping distance; and 3) performing a snapping based
on the result of Part 2 to connect those road segments, which remained
unconnected from Part 1. The findings show that data on local roads on the Fort
Berthold Reservation from the two different sources are joined through the
standard process, and the process saves considerable time and resources
required for fixing the road network. The standard process that has been
developed here can be applied to a variety of other Indian road information
integration projects to join not only physical road segments, but also plural
attribute information. The process will also be useful for a variety of other
projects integrating road information, which is available to the public, in
order to overcome financial and time limitations.
