PRESENTATION DESCRIPTIONS

ADaM/Data Mining
The Algorithm Development and Mining (ADaM) system was developed in response to the need to mine large scientific data sets for geophysical phenomena detection and feature extraction. It provides a variety of processing tools, which allow easy integration of spatial and temporal variables of earth science data sets. Algorithms that can detect a variety of geophysical phenomena were also implemented within the system to address the needs of the earth science community. datamining.itsc.uah.edu/adam   Presentation

ArcGIS
Several presentations by ESRI on the use of ArcGIS.

DIMES/GrADS
DIstributed MEtadata Server (DIMES) is a metadata search and navigation system based on XML technology. DIMES was developed under SIESIP project for handling a wide variety of diverse metadata for small data providers. In contrast to most other work on XML-based metadata which are focused on defining the XML structure for specific disciplines, DIMES is used to support a wide variety of metadata with minimum semantic enforcement. spring.scs.gmu.edu:8199/servlet/SiesipDataTree
The Grid Analysis and Display System (GrADS) is an interactive desktop tool that is used for easy access, manipulation, and visualization of earth science data. The format of the data may be either binary, GRIB, NetCDF, or HDF-SDS (Scientific Data Sets). GrADS has been implemented worldwide on a variety of commonly used operating systems and is freely distributed over the Internet.  grads.iges.org/grads/

Earth Science Data Services
Earth Science Data Services software system is developed in support of online data search, retrieval, and analysis. We also develop the standards of data service development, communication protocol between the data service and data system, and user interface. The objective is to build a computing environment for data service providers to easily supply and their users to easily utilize the data services. spring.scs.gmu.edu:8000/es

Earth Exploraion Toolbook (EET)
The Earth Exploration Toolbook provides step-by-step instructions for using Earth science datasets and software tools in educational settings. Each chapter of the EET walks users through an example-a case study in which the user accesses data and uses analysis tools to explore issues or concepts in Earth system science. In each chapter, users produce and analyze maps, graphs, images, or other data products. serc.carleton.edu/eet

Earth Science Markup Language (ESML)
The Earth Science Markup Language is based on XML technology and is being designed to answer a critical need. ESML provides a solution for representing scientific data/metadata that will allow scientific data and applications to interoperate without the costly overhead of data format conversion. At this Workshop, participants will receive a detailed overview of the ESML project and current status, demonstrations of ESML tools and services, guidance on creating ESML definitions for your data, and information on application integration of ESML support.  esml.itsc.uah.edu   Presentation

Federation Interactive Network for Discovery (FIND): Mercury and GCMD
This workshop will provide instructions in making full use of the Federation search capabilities. www.esipfed.org/find  Presentation

GIS for Observation Networks
Geospatial Databases and Geographic Information Systems (GIS) have become valuable tools for integrating data from disparate sources and for accessing and monitoring climate and weather observing systems. Two systems under development at NOAA are discussed. One of the systems was developed to address the National Research Council's recommendations for monitoring observation network performance and is known as the Health of the Networks project. Currently, the "health" of two NOAA observing networks is monitored using various performance indicators. While the suite of indicators varies from network to network, special attention is paid to changes in baseline performance and to the detection of undocumented observation changes. Examples of performance indicators are provided and a simple framework permitting feedback between the monitoring system and network managers is discussed. In 2003, NOAA initiated its first-ever comprehensive review of all its observing systems and their interrelationships. This second example is called the baseline NOAA Observing System Architecture (NOSA). NOAA owns and operates just under 100 observing systems and the geospatial locations of these observing systems have been incorporated into an ArcIMS interactive map portal. The interactive map allows users to locate observing systems in a particular area and do queries with other observing systems.

IDL/Macromedia Client Visualization: Putting Earth Data on Users' Desktops
The Data Discovery Toolkit and Foundry, led by members of the Earth Data Discovery Consortium ESIP, offers an end-to-end solution for earth data access and visualization on the student's desktop. The application development environment is based on a combination of IDL (a commercial data-use software, for data access and manipulation) and Macromedia Director (a widely used authoring environment, for interactive user interface development). The result is a capability to put research level tools into simple, interactive user applications. This workshop will show how you can join the Foundry as a member and use the free tools to build your own custom application. This workshop is for anyone interested in bringing real data to the desktop. For beginners, this workshop explains the data pathway from the earth data archive, to the scientist, to the application builder, and finally the classroom or museum kiosk. For application developers (or those who might like to try their hand) this workshop will also outline the use of the plug-in technology that moves data from IDL to Director. A sample software product will be distributed. This product, the World Ocean Atlas 1998 Viewer, was the result of the Ocean strand of the 2002 DLESE meeting, and was created by The New Media Studio and Bill Prothero at UCSB. Both the working cross-platform application and the source code will be distributed.

Magic Planet...We Need Your Data!
This workshop will be focused on identifying datasets available to display on Magic Planet on a regular basis. Dave is interested in identifying technologies, data sources and collaborative opportunities to distribute earth and space science content to Magic Planet on a consistent basis.

MapServer-WCS
This workshop presents a recent MapServer extension to support OGC Web Coverage Services (WCS), work funded as a SEEDS prototype. The WCS specification allows exchange of spatio-temporal data between applications as opposed to generating static maps for visualization over the web. In parallel with OGC's Web Mapping Services (WMS) and Web Feature Services (WFS), the WCS specification defines three fundamental operations: GetCapabilities, GetCoverage, and DescribeCoverage. These operations will be briefly described; examples will be given of how MapServer (and its underlying components including GDAL) has been extended to facilitate data discovery and spatial data product (coverage) generation in a web environment. A spatio-temporal query engine was added to support range queries using a new spatio-temporal tile index. Along with the fundamental WCS operations, the query engine and temporal tile indexing will be presented through a hands-on tutorial focusing on a demonstration server for MODIS data. This workshop will benefit all Web GIS application developers and users who are interested in providing/using WCS-based services. Web Site

NEXRAD: Access and Visualization of Doppler Radar Data
NCDC developed free access to the NEXRAD Radar Data (WSR-88D) it now receives electronically in near realtime from all NOAA National Weather Service sites. NCDC also developed a visualization tool for the radar data using Java based GIS applications capable of viewing NEXRAD Level-3 Radar Data directly from disk. The viewer uses Java Web Start, a new feature that launches Java applications over the web.

NOMADS
To address a growing need for remote access to high volume numerical weather prediction and global climate models and data, NCDC, along with NCEP and GFDL, initiated the NOAA Operational Model Archive and Distribution System (NOMADS) project. NOMADS addresses model data access needs as outlined in the U.S. Weather Research Program (USWRP) "Implementation Plan for Research in Quantitative Precipitation Forecasting" and Data Assimilation to "redeem practical value of research findings and facilitate their transfer into operations." The NOMADS framework was also developed to facilitate climate model and observational data inter-comparison issues as discussed in documents such as the Intergovernmental Panel on Climate Change and the U.S. National Assessment. NOMADS is being developed as "A Unified Climate and Weather Archive" so that users can make decisions about their specific needs on time scales from days (weather), to months (El Nino), to decades (global warming).

Reuse Strategies
This session, by the SEEDS Reuse Working Gropu, will provide a brief introduction to some of the concepts of software reuse and look at the opportunities for reuse in earth science community. The session will review the work to date of the NASA Reuse Working Group including the results of a reuse survey conducted by the group, identifying the needs of a reuse catalog, and proposals for a community reuse portal. The session will also discuss ways that Federation members can become involved in the project.

Science Tools
This presentation outlines The BigSur System, a High-Performance Computing system designed for managing the scientific enterprise from end-to-end. BigSur was developed at U.C. Berkeley in the early 1990s, and commercialized in 1997 by Science Tools with NASA funding This presentation briefly discusses the original project goals for BigSur as well as later developments. Other technologies surrounding the BigSur system are also covered, leading to a discussion appropriate uses of these technologies. The architecture is reviewed and strategies for automation and collaboration are discussed. Following the presentation, participants will be invited to view the technologies on a lap-top provided by the author.

SciFlow & Grid Computing
SciFlo is a system for Scientific Knowledge Creation on the Grid using a Semantically-Enabled Dataflow Execution Environment. SciFlo leverages SOAP web services and the Grid Computing standards and enables scientists to do multi-instrument Earth Science by assembling reusable web services and executable operators into distributed computing flows. The SciFlo client & server engines optimize the execution of such distributed data flows and allow the user to transparently find and use data and operators without worrying about the actual location of the Grid resources. The scientist injects a dataflow computation into the Grid by authoring an XML document or filling out an HTML form, and results are returned directly to the scientist's desktop.
Both SciFlo and Grid Computing technologies (Globus Alliance) will be discussed. To illustrate the SciFlo concepts, an example dataflow will be presented in which atmospheric temperature and water vapor profiles from the AIRS, GPS, and MODIS instruments are retrieved using SOAP services, co-registered, and compared on the fly.
