This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System (MTS). The MTS represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads shapefile includes all features within the MTS Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in the MTS that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

Civil townships are a unit of local government, typically subordinate to the County. In Indiana, each township is served by an elected township trustee.Civil townships are primarily represented as Minor Civil Divisions (MCDs) in the source data by the US Census Bureau. Per the US Census, MCDs are the primary governmental or administrative divisions of a county in many states. This data mostly contains MCD boundaries, with some corrected township boundaries (see explanation below). On 1/3/2024, IGIO staff updated the boundaries and/or attributes of 6 townships: Center (Delaware Co), Mount Pleasant (Delaware Co), Eagle (Boone Co), Perry (Boone Co), Union (Boone Co), and Worth (Boone Co). The Delaware County townships were attributed as either Muncie City or Yorktown Town and had associated incorporated area boundaries overlapping the civil township boundary. Boone County had townships attributed as Zionsville City and Whitestown Town and had associated incorporated are boundaries overlapping the real civil township boundary. Civil township boundaries from the 2023 Data Harvest were used when possible to correct geometry, and the neighboring census township boundaries to maintain topology when needed. Eagle and Union townships do not have a populated GEOID since the corrected boundary does not correspond to a census MCD geography to avoid incorrect joins to census tabular data by end users.

This study presents an ArcGIS geoprocessing protocol for quickly processing large amounts of data from publicly available government sources to consider both water quality standards (WQS) and nonpoint pollution source (NPS) control, on a watershed-by-watershed basis to administratively predict locations where nonpoint source pollutants may contribute to the impairment of downstream waters and locations where nonpoint source pollutants are not expected to contribute to the impairment of downstream waters. This dissertation also presents an ArcGIS geoprocessing protocol to calculate the hydrological response time of a watershed and to predict the potential for soil erosion and nonpoint source pollutant movement on a landscape scale. The standardized methodologies employed by the protocol allow for its use in various geographic regions. The methodology has been performed on sites in Linn County and Boone County, Missouri, and produces results consistent with those expected from other widely accepted methods. These protocols were developed studying the movement of atrazine. but may be used for various nonpoint source pollutants that are water soluble, have an affinity to soil binding, and associated with a particular land use. All data and code are available in Mendeley Data (doi: 10.17632/wdjzftxyfd.1).

The NAD is a spatial database containing address data, point location coordinates, jurisdictions, record level metadata and other supporting data for addressable locations including structures, some sub-units within those structures and landmarks as included in the aggregated datasets from providers included therein. Its coverage includes twenty five whole and partial coverage states, including Arizona, Arkansas, Colorado, Connecticut, Delaware, Indiana, Iowa, Maine, Maryland, Massachusetts, Kansas, Montana, New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, Rhode Island, Tennessee, Texas, Utah, Vermont, Virginia and Wisconsin, and the District of Columbia, as well as variable numbers of counties in several states: Anchorage Municipality, Haines and Matanuska-Susitna Boroughs, Yakutat City and Borough, and Dillingham City Alaska; Merced County, California; East Baton Rouge and Terrebonne Parishes, Louisiana; Anoka, Carver, Chisago, Dakota, Hennepin, Isanti, Le Sueur, Ramsey, Scott, Sherburne and Washington Counties, Minnesota; Boone, Christian, Cole, Greene, Jasper, St. Charles, St. Louis, Stone and Taney Counties, and Independence City, Missouri; Campbell, Crook and Teton Counties, Wyoming; Sioux Falls City and Rosebud Sioux Reservation, South Dakota.
