GIS in
Education
 Dr. Joseph J. Kerski
Education – GIS
U.S. Geological Survey, Denver, CO
http://rockyweb.cr.usgs.gov/public/outreach/
The mission of the U.S.
Geological Survey's Education and Communications Program is to
educate data users in the use and application of USGS products and
services. In support of that mission, the program:
- Instructs educators in the use of teaching with
and about geographic information systems (GIS) and other geographic
technologies (remote sensing, Global Positioning Systems (GPS) in the
K-12, community college, and university curricula through the use of
online guidelines, online courses, and hands-on training events.
- Provides spatial data to support the teaching
with geospatial technologies in the curriculum.
- Provides lessons that use geospatial
technologies in the curriculum.
- Provides guidelines as to how to use USGS and
spatial data from other organizations in educational lessons.

Visual Modeling and GIS
Dr. Barbara P. Buttenfield
Professor, Department of Geography,
University of Colorado at Boulder
Visualization and modeling are intricately linked
in a GIS computing environment. GIS analysis is based on visualization.
The output of nearly every GIS operation includes a graphical display.
The reason that 'geospatial data is special', as the saying goes, is
that geographic pattern is sensitive to spatial, temporal and spectral
resolution. It is straightforward to demonstrate these sensitivities.
However just as visualization can inform, it can also deceive. GIS
scientists must rely on visual tools for illustration, and also to
support analysis, inference, and reasoning. Visual Modeling is a term
that encompasses skills in visualization and skills in critical
thinking. Drawing upon the author's work over a period of several
years, examples will include visual modeling of spatial and temporal
patterns, visualization of uncertainty, and designing an interface to
browse very large data archives.

The Value of GIS
to Human-Induced Surface Change Scenario Development
 Dr. Johannes Feddema
Associate Professor, Department of Geography,
University of Kansas, Lawrence, Kansas
This discussion will review some basic concepts of
a GIS and how it can be used for manipulating and evaluating databases
in Earth system modeling activities. The talk will focus on three
aspects of GIS that might be of use to the NCAR community. First there
will be a brief review of GIS systems and how such systems might be
used for data
presentation and serving data over the Internet. Second, some examples
will be given of GIS tools that can assist scientists to manipulate a
wide variety of data sources for modeling purposes and climate impact
assessment. Third, an example application for developing land surface
change scenarios will be demonstrated. This study links satellite
derived human population data, land-use data and a global soil
degradation database to create data inputs for simulating the potential
impacts of human induced land surface change on climate.

Geospatial
Databases as a Foundation for Environmental Data Management
Dr. Ted Habermann
NOAA National
Geophysical Data Center
Recent developments in Geographic Information
Systems (GIS), Relational Database Management Systems (RDBMS),
and the World Wide Web (WWW) have revolutionized our capability to
share data among scientists and with the world.
Geospatial databases are standard relational databases (Informix, DB2,
Oracle) that are extended to include the capability to store and access
spatial objects (points, lines, and polygons) and to perform spatial
operations on those objects (find all points within a polygon). These
databases support access using a wide variety of standards-based RDBMS
and GIS tools and provide a powerful piece of a foundation for
environmental data management. Dr. Habermann described geospatial
databases and discussed examples of applications to environmental data.

Hydrologic
Modeling For Flash Flood Operations
Dr. Lynn E. Johnson
Professor of Civil Engineering,
Department of Civil Engineering,
and Director, MEng-GIS Program
University of Colorado at Denver, Denver, CO
Modern weather radars deployed across the U.S.
provide rapid estimates of rainfall distribution and intensity.
Availability of these rainfall products prompts linkage with hydrologic
models of varying complexity. This seminar reviewed procedures for
rainfall estimation and linked hydrologic modeling, and assessments of
these for flash flood forecasting operations.

Open GIS Consortium
 Dr. Carl
Reed
Executive Director, Open GIS Specification Program
Open GIS Consortium
Fort Collins, Colorado
Dr. Reed was invited by the Unidata to present an overview
of the Open GIS Consortium activities. The following topics are
covered: a short history of the OGC; the Interoperability Program and
the Specification Program; current specifications and current
interoperability initiatives; and work related to NSDI and GSDI
(portals).

GIS Meterology
Dr. Scott Shipley
Department of Geography, George Mason University, Fairfax, VA
NPOESS Program Manager, Raytheon ITSS, Lanham, MD
An introduction to Geographic Information Systems
(GIS) and their applications in Hydrometeorology Basic GIS functions
are reviewed, and GIS analysis strategies for a wide range of weather
observations and weather modeling products are examined. Selected
desktop applications of GIS in meteorology are surveyed, including NWS
AWIPS.
