Papers on Data, Data Access and the Web

Creating Spatial Data: Finding the Right Tool for the Job ( ESRI Tech Lit Site ) Date: June 1998 Subject: This white paper explains how the biggest investment in implementing a GIS is data creation and maintenance. This paper outlines the issues to consider when creating GIS data and how to create the best data either from scratch or from conversion of existing digital data such as CAD. (78 KB / 10 pages)

Tel:(207) 581-2175 Fax:(207) 581-2206 ) "Selection of appropriate policies for dissemination of GIS data, products, and services continues to be an important issue for ma ny local government agencies. GIS agencies are currently making dissemination policy decisions with little data or information on the economic, legal and political ramifications of choosing one policy or practice over another."

Information Center for the Environment: Public Access to Natural Resource Data (1996 ESRI Conf. Paper, Karen Beardsley and James F. Quinn)...The Information Center for the Environment (ICE) is housed in the Division of Environmental Studies at the University of California, Davis (UCD)...The goals of UCD ICE include providing GIS, database systems, and modelling support to environmental resource projects, and developing easy-to-use public access to a wide variety of environmental information. In support of these goals, UCD ICE staff have developed an interactive mapping query system known as ICE MAPS that allows World-Wide Web users to create and download customized maps.

Promoting a Free Access or Minimal Cost of Dissemination Arrangement for Government-Held Geographic Information Systems Data (1995 ESRI Conf. Abstract, Keene Matsunaga, Jack Dangermond) ...This paper focuses on the role that the governments play in providing public access to GIS data at a minimal cost of dissemination. It analyzes the First Amendment and the U.S. Copyright Act's underlying policies as they relate to the providing of public access to GIS data.

Your Right to Know in the UK (1997 ERSI Paper, Susan Pipes, Friends of the Earth, 26-26 Underwood Street London, N1 7JQ UNITED KINGDOM, Telephone: 44-171-566-1637 Fax: 44-171-490-0881 E-mail: Defining Issue: Friends of the Earth (FOE) has been using spatial analysis as a campaigning tool for over six years. However, in order to maintain the integrity of our GIS research we need to have better access to the United Kingdom government's environmental information. Unlike in the United States there is no Freedom of Information Act in the U.K. at present, and it is the aim of this paper to chart the progress made by FOE and others in obtaining better access to environmental information in the U.K. - our legal challenges, our winning campaigns and our present battles. One Solution: The paper will give a live Internet demonstration of the clear example, FOE has set for the U.K. government in the provision of real access to environmental information. FOE has published the government's own Chemical Release Inventory , a complex database of chemical emissions recorded at U.K. factories, on the Internet via a mapping interface. By entering their post code (or ZIP Code) the user generates a map centered on their own home that identifies local factories. These can then be clicked on to discover emission levels from each individual factory. Voted the Best Non-Commerical Site by GIS World, FOE's version of the Chemical Release Inventory has revolutionized access to this information. In 1994/95 the U.K. government recorded 760 requests for this information. In 1995/96 FOE responded to 25,000 requests for the same information.
