Put the world of GIS data resources at your command— GIS users routinely encounter key questions about the dataneeded for their projects: Where did the data come from? Is thisthe best data available? How can the data be loaded to make itwork? What about creating original data? With a broad range of GISdata options to choose from, knowing how to find, select, and usethe most appropriate resources for different purposes is absolutelyessential in order to keep costs down and make the most of thetechnology. Filled with crucial information for today's GIS users, this bookoffers a comprehensive, straightforward reporting on GIS datasources--what they are, hot to find them, and how to determine theright source for a given project. Beginning with a thorough reviewof the basic GIS data types and groups, GIS DataSources shows hot to define specific data needs for aproject and accurately envision how the data will look and act onceit is applied. The next step is to locate and obtain the data. Here the bookpresents a wealth of data sources, with added guidance on creatingoriginal data and important information on suitable applicationsfor different types of data. Nuts-and-bolts material on dataformats, media, compression, and downloading helps users acquireand use GIS data easily and avoid the technical snags that can slowa project down. In addition, the book's extensive resource listings providedetails on where to find GIS information on the Internet, and acomplementary Web site (www.gisdatasources.com) provides furtherdata links and updates to help jump-start your projects. With invaluable time-and cost-saving advice and answers to ahost of common GIS data questions, GIS Data Sourcesis a powerful new tool for users of the technology in anyfield. Drew Decker is Texas State Cartographer with the Texas NaturalResources Information System in Austin, Texas. He serves asCo-chair of the Texas Geographic Information Council's TechnicalAdvisory Committee and is the Project Manager of the TexasStrategic Mapping Program.

The environment for obtaining information and providing statistical data for policy makers and the public has changed significantly in the past decade, raising questions about the fundamental survey paradigm that underlies federal statistics. New data sources provide opportunities to develop a new paradigm that can improve timeliness, geographic or subpopulation detail, and statistical efficiency. It also has the potential to reduce the costs of producing federal statistics. The panel's first report described federal statistical agencies’ current paradigm, which relies heavily on sample surveys for producing national statistics, and challenges agencies are facing; the legal frameworks and mechanisms for protecting the privacy and confidentiality of statistical data and for providing researchers access to data, and challenges to those frameworks and mechanisms; and statistical agencies access to alternative sources of data. The panel recommended a new approach for federal statistical programs that would combine diverse data sources from government and private sector sources and the creation of a new entity that would provide the foundational elements needed for this new approach, including legal authority to access data and protect privacy. This second of the panel's two reports builds on the analysis, conclusions, and recommendations in the first one. This report assesses alternative methods for implementing a new approach that would combine diverse data sources from government and private sector sources, including describing statistical models for combining data from multiple sources; examining statistical and computer science approaches that foster privacy protections; evaluating frameworks for assessing the quality and utility of alternative data sources; and various models for implementing the recommended new entity. Together, the two reports offer ideas and recommendations to help federal statistical agencies examine and evaluate data from alternative sources and then combine them as appropriate to provide the country with more timely, actionable, and useful information for policy makers, businesses, and individuals.

The National Agricultural Statistics Service (NASS) is the primary statistical data collection agency within the U.S. Department of Agriculture (USDA). NASS conducts hundreds of surveys each year and prepares reports covering virtually every aspect of U.S. agriculture. Among the small-area estimates produced by NASS are county-level estimates for crops (planted acres, harvested acres, production, and yield by commodity) and for cash rental rates for irrigated cropland, nonirrigated cropland, and permanent pastureland. Key users of these county-level estimates include USDA’s Farm Services Agency (FSA) and Risk Management Agency (RMA), which use the estimates as part of their processes for distributing farm subsidies and providing farm insurance, respectively. Improving Crop Estimates by Integrating Multiple Data Sources assesses county-level crop and cash rents estimates, and offers recommendations on methods for integrating data sources to provide more precise county-level estimates of acreage and yield for major crops and of cash rents by land use. This report considers technical issues involved in using the available data sources, such as methods for integrating the data, the assumptions underpinning the use of each source, the robustness of the resulting estimates, and the properties of desirable estimates of uncertainty.

This Brief provides a detailed guide to national data sources that collect and report data on homicides in the United States, and some key international sources abroad. It provides in-depth coverage of well-known sources, and highlights more obscure sources, providing a useful tool for research design and planning across disciplines. This Brief includes detailed discussions of the benchmark sources in the United States: police data compiled by the Federal Bureau of Investigation’s Uniform Crime Reporting Programs, as well as the Center for Disease Control and Prevention’s National Center for Health Statistics’ National Vital Statistics System. It also brings to light in one place many other less commonly-known sources for the United States. The author also highlights international data sources with worldwide data, but not country-specific studies. For each source covered, this unique work provides discussion of how to access the data source, interpret data from the source, and provides necessary background information about strengths and weaknesses of the sources. It does not presume expertise in statistics or methodology, and assumes no prior exposure to the data sources described. It is organized by data source, with some comparisons between the sources. It will be useful as a guide for researchers in Criminology and Criminal Justice, Public Administration, Demography, and any related field interested in homicide statistics.
