Some sources of geospatial data.

• Geospatial and Statistical Data Center - Geostat supports a wide range of academic and scholarly activities through access to extensive collections of numeric and geospatial data files; computing facilities and software for data manipulation, research, and instruction; and a suite of Internet-accessible data extraction tools.
• USGS National Geospatial Data Clearinghouse - General Information - The USGS node of the National Geospatial Data Clearinghouse is a component of the National Spatial Data Infrastructure (NSDI). The Clearinghouse provides a pathway to find information about geospatial or spatially referenced data available from USGS. The information is in the form of metadata. Metadata or "data about data" describe the content, quality, condition, and other characteristics of data. Metadata are used to organize and maintain investments in data, to provide information to data catalogs and clearinghouses, and to aid data transfers.
• Content Standard for Digital Geospatial Metadata (CSDGM) - The objectives of the standard are to provide a common set of terminology and definitions for the documentation of digital geospatial data. The standard establishes the names of data elements and compound elements (groups of data elements) to be used for these purposes, the definitions of these compound elements and data elements, and information about the values that are to be provided for the data elements.
• ASPRS: The Imaging & Geospatial Information Society
• Starting the Hunt: Guide to Mostly On-line and Mostly Free U.S. Geospatial and Attribute Data - This list isn't exhaustive, nor was it intended to be. Its purpose is to provide a starting point when beginning to track down sources of digital geospatial data and attributes related to the US.
• Geospatial Solutions Home Page 2000 - Geospatial Solutions helps people benefit from GIS and related technologies by providing solutions-based case studies, technical tutorials, policy updates, news, and new product information.
• National Geospatial Data Framework - The UK geospatial data infrastructure. Aim is to facilitate the unlocking of geospatial information.
• Digital Map and Geospatial Information Center - The mission of Geospatial Information & Technology Association is to provide excellence in education and information exchange on the use and benefits of geospatial information and technology in telecommunications, infrastructure and utility applications worldwide.
• Geoplace - Geographic Information Systems - GIS Publication
• Geocoding - The resources of e-business are available to help real estate agents sell brick-and-mortar locations. Real-estate boards, brokers, and multiple listing service (MLS) providers can purchase new Web- and client/server-based MLS solutions to expedite and increase sales. Clients and agents can access critical information, such as property photos, maps, community information and an array of demographic data. The common key to this data is geography. All of this information can be brought together through street-level geocoding and made usable by associating coordinates to individual addresses.
• Geospatial Support Team - This directory contains a miscellaneous collection of GIS utilities and some data files. The executable programs are in EXE (DOS/Windows) format. Included is a PC version of the public-domain GIS program MOSS (Map Overlay and Statistical System.) Also included are conversion utilities between some of the popular GIS and graphics formats (MapInfo, AutoCad, ESRI, Tiger, VPF, SDTS, and MOSS, and probably some others.) The programs were contributed by various parties and are in varying states of development. All material dates from 1998 or before.
• U.S. EPA Node of National Geospatial Data Clearinghouse (GIS data) - Clearinghouse, a component of the National Spatial Data Infrastructure (NSDI). This node provides a pathway to find information about geospatial data available from the EPA. Geospatial data is used in Geographic Information Systems (GIS) to identify the geographic location and characteristics of natural or man-made features and boundaries on the earth.
• Geospatial References: Index - A collection of references to technical resources for building online geospatial information systems. The focus is on Australasian resources.
• An overview of GIS and geospatial data - What distinguishes GIS from other forms of information systems, such as databases and spreadsheets, is that GIS deals with spatial information. GIS has the capability to relate layers of data for the same points in space, combining, analysing and, finally, mapping out the results. Spatial information uses location, within a coordinate system, as its reference base. The most common representation of spatial information is a map on which the location of any point could be given using latitude and longitude, or local grid references such as the National Grid.
• Geospatial Resources - This guide lists paper and digital geospatial resources available in the HSU Library or on the Internet. Most paper and local electronic resources are located either in the Atlas and Map Collection or the US Documents Collection.
• GeoConnections - Home Page - CGDI - Canada's geographic information on the Internet.
• Optimizing Web Access to Geospatial Data - With the aid of a 1997 Federal Geographic Data Committee CCAP Award, Cornell's Albert R. Mann Library recently established the Cornell University Geospatial Information Repository (CUGIR), a Web-based clearinghouse containing geospatial data and metadata related to New York State. The staff at Mann Library has established an efficient model for spatial data distribution. This paper describes the processes, problems, and solutions involved in the creation of a geospatial data distribution system.
• Free Geospatial Data in Canada - The purpose of this website is to collect opinions from Geographic Information System (GIS) users in regard to charging for government created spatial data.
• GeoSpatial International - Spatial Information and Natural Resource Consulting.
• Dataworlds - How will people interact with data in five years? One thing is for sure, the world will soon outgrow two dimensional representations. "Virtual Reality" ("VR") technology is opening up the doors to an immersive experience in the world of one's own information. The multidimensional and interactive nature of "VR" provides a vastly superior level of comprehension of the underlying information as compared to static, two-dimensional models such as paper and the computer screen.
• Global Information Infrastructure: Agenda for Cooperation - The nations of the world are diverse in size, levels of economic development, political, economic and social structures, and language and culture. We believe, however, that despite these differences a broad community of interest exists among countries to better the lives of the citizens of the world -- all citizens. Regardless of a country's overall level of technological development, active participation in the evolving GII can provide the tools to improve the quality of life.
  For example, the GII can facilitate health care delivery through telemedicine, linking rural physicians to major medical facilities for off-site consultations on difficult diagnoses. If only a computer and a wireless link are available, they can provide a data base search and on-line questioning of a consulting expert. If fiber optic networks are available, telemedicine services can include remote visual examination. Such services are a boon to rural physicians. Similarly, the GII can quicken response time for disaster relief. It can transform education with computer-based multimedia systems that teach with both sight and sound, greatly increasing retention rates and providing children access to greater educational opportunities. It can provide new tools to assist persons with disabilities. The GII can also make factories more efficient, speed the creation of new and better goods and services, cut the cost of business by improving efficiency, develop new jobs and markets, increase trade, and facilitate flows of information across borders.
  That is not all. A well-developed GII can enhance democratic principles and limit the spread of totalitarian forms of government. Representative democracy is founded on the premise that the best political processes are those in which each citizen has the knowledge to make an informed choice and the power to express his or her view. The GII will allow wider and greater citizen participation in decision-making by providing the additional means for individuals to keep informed, as well as to express their opinions. Through the GII, the world's citizens will have the opportunity to share information and cultural values, fostering a greater sense of global community. By encouraging exchanges of ideas, goods, and services among all countries, the GII can contribute to a framework for lasting peace.
  Realizing these benefits will not be easy -- our vision of the GII presents a challenge that cannot be undertaken by a single country, nor overcome by government fiat. Rather, its success will depend in large measure on innovation and investment by the private sector. As the principal source of expertise and capital, the private sector should, in response to marketplace demands, determine what technologies to pursue, set the pace of development, establish the appropriate standards, and develop new services and applications. For their part, governments can facilitate these activities by creating a legal and regulatory environment that supports efficient investment and innovation, and promotes full and fair competition. Governments can also provide leadership by supporting testbeds for new technologies, fostering the transfer of resulting technologies to the private sector, promoting the assimilation and use of applications and technology through government procurement, and developing applications that support government operations and dissemination of government information.
• Spatial data Infrastructure - CSI recognizes the value of creating mechanisms for standardizing and integrating data sets. We applaud efforts around the world focusing on the development of Spatial Data Infrastructure ­spatial data infrastructure encompasses the policies, standards and institutional arrangements involved in delivering spatially-related information from many different sources to the widest possible group of potential users. We encourage you to visit the links on this page to learn about Spatial Data Infrastructure initiatives around the world. We have also included links to papers dealing with issues of spatial data infrastructure and information policy.
• Creating the Canadian Geospatial Data Infrastructure - A large part of human activities are closely linked to a geographic location. Governments and business capitalize on this fact by creating digital geospatial data - data based on location - for a wide range of decision making, analysis of change impact and the management of many diverse resources. Since information technology is the basis for many of these activities, governments at all levels are collaborating with each other and with industry to develop the infrastructure to more efficiently collect, integrate, manage, and disseminate geospatial data using the emerging information highway.

• International Society of Spatial Sciences - The focus of the International Society of Spatial Sciences (ISSS: "I-triple-S) is to place in a core position those sciences, of spatial character, that are often relegated to the periphery within academic institutional structure. Such sciences are, to name only a few, geology, geography, and astronomy. In moving along this continuum from the center of the Earth to the outer reaches of the universe, one might imagine a whole host of sciences that could also be included (from oceanography to atmospheric science to regional science). Thus, ISSS offers a platform from which individuals and institutions devoted to some aspect of spatial science might further their interests. This new organization is founded within the mantle of Community Systems Foundation, a non-profit corporation in Ann Arbor, Michigan. Because electronic networks are easily accessible at a low cost, we envision a wide range of possibilities - from electronic journals, monographs, and books, to digital teaching materials, to materials available on Internet. Join us on this electronic platform devoted to the spatial sciences.
