Recent Advances in Geographic Information
Science
 Dr. Micheal Goodchild
Associate Director of the Alexandria Digital Library Project,
National Center for Geographic Information and Analysis,
and Professor of Geography at UC Santa Barbara
Time: 1:30pm
Location: Foothills Laboratory 2, Room 1001
GIScience emerged about ten years ago as a
multidisciplinary field devoted to the study of geographic information,
and the fundamental principles on which geographic information
technologies are based. I give a brief history of the field, and review
some of the major debates within it. Uncertainty is a major issue in
GIScience, and much research on the topic has occurred in the past
decade. I review the motivation for research on uncertainty, and some
of the most significant advances. Since the popularization of the
Internet very substantial investments have been made in the
infrastructure for sharing geographic information, through such
initiatives as the National Spatial Data Infrastructure. I review the
current state of the art, and its expression in the vision for an
integrated portal to digital representations of the planet.

Topography, Microclimate, and Vegetation:
GIS-based Modeling Approaches
Paul Rich
GIS Team Leader, Earth and Environmental Sciences Division
Los Alamos National Laboratory
Time: 3:30pm
Location: Foothills Laboratory 2, Room 1001
Topography has a strong influence on spatial and
temporal patterns of microclimate, including such physical factors as
temperature, precipitation, soil moisture, and evapotranspiration. In
turn, these physical factors are major determinants of vegetation
patterns. Early work on the vegetation of the University of California
Big Creek Reserve provided lessons that have served well in a career of
work ranging from geometric models of solar radiation, to coupling
between microclimate and basic biology, to GIS-based modeling tools. A
current effort focuses on merging capabilities of the predecessor solar
radiation modeling tools TopoRad and the Solar Analyst as ArcRad, a new
capability of ArcGIS 9. The core viewshed algorithm accounts for the
geometric effects of both topography and plant canopies across a broad
spectrum of temporal and spatial scales.

Monitoring and measuring landscape changes:
Using imagery for building GIS based on monitoring and modeling systems
Dr. Andrew Brenner
North East Regional Manager
Space Imaging
Time: 10:30am
Location: Foothills Laboratory 2, Room 1001
 The world is constantly changing,
yet our datasets are static, so how can we create data management
infrastructures that monitor and measure change. Imagery and remote
sensing allow us to update and revise datasets in cost effective and
efficient manners. These data allow us to evaluate changes spatially
and temporally, enabling us to update input data into our varied models
of reality.
This seminar will cover how digital imagery can be
used to monitor changes in the landscape, for both terrestrial and
aquatic systems. It will outline the processes that allow the
development of GIS data sets from imagery, and the types of data layers
that can be developed. The seminar will also show practical examples of
how these data can be integrated with other GIS layers as inputs to
landscape change, water quality and run off, atmospheric and habitat
models. The seminar will also cover how imagery and GIS can be combined
to track landscape changes, both anthropogenic and natural, within
enterprise GIS systems.
