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.
Highlights
As of 2013, 2.9 million residents in the United States are identified as Native Americans and Alaska Natives, and the population growth rate of them is much faster than that of the total US population
From 2000 to 2010, the Native American and Alaska Native population in the United States has increased by 18.4 percent, while the growth of the total US population was 9.7%
We developed a standard process to integrate road information data coming from state and federal sources for the Fort Berthold Reservation, and applied a three-part integration process to producing integrated road information
Summary
As of 2013, 2.9 million residents in the United States are identified as Native Americans and Alaska Natives, and the population growth rate of them is much faster than that of the total US population. From 2000 to 2010, the Native American and Alaska Native population in the United States has increased by 18.4 percent, while the growth of the total US population was 9.7%. The Native Americans and Alaska Native population in North Dakota grew 16.8 percent [1]. According to United Census Bureau [3], the Fort Berthold Reservation with Three Affiliated Tribes is where the fastest growth of Indian population in North Dakota occurred from 2000 to 2012, increasing from 3799 to 4275 by 11.1%. Recreational and historical facilities are organized to preserve the Three Affiliated Tribes’ culture, and there are a few manufacturing firms which provide members of the Three Affiliated Tribes with job opportunities [4] [5]
