Extractions: Explorers from competing teams race to find a mysterious lost city in the heart of Africa. The American team is continuously in touch with its Houston home base through satellite communications. In flight, team leader Karen Ross displays a map of Africa on her computer screen and notes the multicolored lines suggesting different routes from city to city and into the rain forest. Each pathway is accompanied by a precise estimate of travel time to the final destination. Zooming in on the target area, she switches to satellite images and interprets them in shades of blue, purple, and green. At each checkpoint, the team reports its progress and gets a revised estimate of arrival time. Beset by difficulties, the expl orers ask for a faster route, but the computer says the alternative is too dangerous. A simulation model with data representing geology, terrain, vegetation, weather, and many other geographic factors predicts local hazards, including the impending erupti on of a nearby volcano. The Americans take the faster route anyway and beat the odds. his fictional account of emerging geographic information system (GIS) technologies comes from Michael Crichton's 1980 novel Congo , which was made into a 1995 movie. The same technologies were highlighted in Clive Cussler's 1988 techno-thriller

Extractions: A Geographic Information System (GIS) is a database management system for the display and analysis of digital geospatial data. GIS combines mapping capabilities, databases of geographic and feature information, and spatial analysis to allow users to look at an area in relation to other areas, in relation to changes over time, and in relation to various factors. ESRI, a leading manufacturer of GIS software, provides an " About GIS " webpage. Other introductory information is available from USGS and from the GIS-L listserv GIS Services Library staff are available to meet one-on-one with UW students, staff and faculty, and to assist in retrieving data. The Libraries provides these users with full access to geographic information systems (GIS) software and data owned by the Libraries. We will assist users in identifying additional sources of commercial and public-domain data. For more information, please contact GIS staff via email at gis@lib.washington.edu

PostGIS Geographic Objects For PostgreSQL
Spatially enables the server, allowing it to be used as a backend spatial database for geographic information systems (GIS).
http://postgis.refractions.net/

Extractions: PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS Simple Features Specification for SQL " and will be submitted for compliance testing at version 1.0. PostGIS has been developed by Refractions Research Inc as a research project in open source spatial database technology. PostGIS is released under the GNU General Public License . We intend to continue development as time and resources permit. Our list of future projects includes enhanced technology for data loading and dumping, user interface tools for direct data access and manipulation, and support for advanced topologies at the server side, such as coverages, networks, and surfaces.
Homeland Security And Geographic Information Systems
Homeland Security and geographic information systems. How GIS and mapping technologycan save lives and protect property in postSeptember 11th America.
http://www.fgdc.gov/publications/homeland.html

Extractions: Introduction Timely, accurate information, easily accessed and capable of being shared across federal, state, and local political jurisdictions is fundamental to the decision making capability of those tasked with the homeland security mission. But without the real-time ability to quickly visualize activity patterns, map locations, and understand the multi- layered geospatial context of emergency situations, homeland security will not be achieved. The current state of geospatial information technology can provide decision-makers the data they need to confidently confront a wide variety of threats including natural disasters, terrorist attacks, sabotage, and similar crises. However, the current implementation of that technology, across all the federal, state, and local agencies and jurisdictions necessary to fully coordinate an effective response, is seriously lacking in specific areas. As the concept of Homeland Security becomes infused into the work-a-day pattern of government and the everyday life of our citizens, decision makers will greatly profit from the crisis management "edge" that GIS provides. Homeland Security leaders should understand and implement the policy changes necessary to fully realize this technology's capability, and make the management decisions necessary to implement it on a national basis.

http://sal.kachinatech.com/E/6/

Extractions: GIS - Geographic Information Systems are the combination of data management with content and locational indexing, and spatial representation and analysis techniques to facilitate the understanding of real-world entities in their context and interactions. GIS, therefore, records objects in terms of their location and characteristics, and provides analysis and display tools to permit the modeling of the objects and the further modeling of the effects of changes to the characteristics and/or location of the objects upon both themselves and the surrounding environment. GIS techniques involve elements of database systems, cartography, statistical and other analytical processes, computer graphics, and general geographic awareness.

Extractions: Cartography and Geographic Information Systems A geographic information system (GIS) is simply a database of information about natural and man-made geographic features such as roads, buildings, mountains... These systems can be used for making maps, but also for analyzing data e.g. for facility location. There has been some communication between the geometry and GIS communities (e.g. geographer Michael Goodchild gave an invited lecture on "Computational Geography" at the 11th ACM Symp. Comp. Geom. ) but more could be done to bring them together. Geographic problems already visible in the geometry community include interpolation of surfaces from scattered data , overlaying planar subdivisions, hierarchical representations of terrain information, boundary simplification, lossy compression of elevation data (e.g. by using a piecewise linear approximation with few facets), and map labelling. Other interesting geometric issues include handling of approximate and inconsistent data, matching similar features from different databases, compression of large geographic databases, cooperation between raster and vector representations, visibility analysis, and generation of cartograms (maps with area distorted to represent other information such as population). A particularly important geometric data structure in geographic analysis is the Voronoi diagram , which has been used for to identify regions of influence of clans and other population centers, model plant and animal competition, piece together satellite photographs, estimate ore reserves, perform marketing analysis, and estimate rainfall.
