Development of EDMI Calibration Baseline, HR-241, 1984

Electronic distance measuring instruments (EDMI) are used by surveyors in routine length measurements. The constant and scale factors of the instrument tend to change due to usage, transportation, and aging of crystals. Calibration baselines are established to enable surveyors to check the instruments and determine any changes in the values of constant and scale factors. The National Geodetic Survey (NGS) has developed guidelines for establishing these baselines. In 1981 an EDMI baseline at ISU was established according to NGS guidelines. In October 1982, the NGS measured the distances between monuments. Computer programs for reducing observed distances were developed. Mathematical model and computer programs for determining constant and scale factors were developed. A method was developed to detect any movements of the monuments. Periodic measurements of the baseline were made. No significant movement of the monuments was detected.

2006 Vineyard Survey Summary, 2006

Survey Methodology: The Iowa Department of Agriculture and Land Stewardship (IDALS) Bureau of Horticulture provided USDA National Agricultural Statistics Service (NASS) Iowa Field office with a complete list of apple and grape growers expected to be in operation. These operations were mailed a questionnaire and a telephone follow-up of non-respondents was conducted. The survey data was edited for reasonableness, and then summarized using statistical software. There were 236 operators who reported they did own, lease or operate a grape vineyard in 2006. The same operators reported 538 acres of grapes.

2006 Winery Survey Summary, 2006

Survey Purpose: The purpose of the survey was to measure the grape consumption, production, and expected needs by cultivar. Survey Methodology: The Iowa Department of Agriculture and Land Stewardship (IDALS) Bureau of Horticulture provided USDA National Agricultural Statistics Service (NASS) Iowa Field office with a complete list of wineries expected to be in operation. The wineries were mailed a questionnaire and a telephone follow-up of non-respondents was conducted. The survey had an 87 percent response rate. The survey data was edited for reasonableness, and then summarized using statistical software.

Iowa’s Historic Automobile Roads A National Register Study of Pre-1948 Arterial Highways, 2009

This study of Iowa’s Historic Automobile Roads has been prepared by the Highway Archaeology Program under the terms of an annual cultural resource surveys contract between the Iowa DOT and The University of Iowa. Under this agreement, state transportation funds are appropriated by the Iowa DOT for The University of Iowa Highway Archaeology Program to locate and determine the significance of cultural resources in the area of proposed highway and transportation improvement work. Cultural resources include archaeological, historical, and architectural sites. The study of Iowa’s Historic Automobile Roads reported herein, including archival research and survey, was conducted between June 2002 and June 2007, by Marlin R. Ingalls and Maria F. Schroeder. The University of Iowa Highway Archaeology Program is solely responsible for the content and accuracy of these reports with respect to site location description, interpretation, and recommendations. Duplicate project reports are filed at the State Historic Preservation Office (SHPO), Community Programs Bureau in Des Moines. Illustrations in this report may have been altered for clarity and sized to fit the page.

An Architectural and Historical Survey of Public Libraries in Iowa 1870-1940, 1980

The public library movement f the early twentieth century was a national phenomenon, in which Iowa, along with its neighboring states, played a prominent role. In 1900, the Iowa Library Commission noted 48 free public libraries in the state. Today there are approximately 500, in towns ranging in size from Beaman, with a population of 222, the Des Moines, the state capitol. Iowans took enthusiastic advantage of Andre Carnegie's library philanthropy. In 1919, the Carnegie Corporation stopped funding libraries, 101 building has been erected in Iowa with Carnegie funds. Iowa place fourth among the states in terms of the number of communities obtaining Carnegie buildings, fifth in dollar appropriation per one hundred population and eighth in the total amount of money given by Carnegie to a state. These figures provide some measure by which interest in popular education among Iowans of the period can be judged. Today these early libraries, often the most distinctive public libraries in small or medium-sized towns, are physical foci in the townscapes of their communities and centers for a variety of educational and social activities. This survey was initiated by the Division of Historic Preservation in 1977. It grew out of the need to provide a framework within which libraries could be evaluated for National Register action. Several libraries (Des Moines, Grinnell, Eagle Grove, Carroll) has been recent candidates for the Register. There was every indication that enthusiasm for old library buildings was increasing and that more nominations could be expected in the future. The attrition rate among early library buildings was (and is) growing. Most libraries were built on limited budgets (Carnegie did not squander his money) and, despite the fact that future expansion was usually a conscious consideration in their design, they are rapidly becoming obsolete, due to expanding collections and changing styles of librarianship. If the protection of the threatened with demolition or alteration, action needed to be taken.
