EOGEO Overview and Current Activities (PPT) by Pericles Nacionales — last modified 2005-11-19 16:26

Presenter: Allan Doyle, EOGEO Abstract: The EOGEO Workshops started in 1996 as an outreach activity by the Committee on Earth Observation Satellites (CEOS). The workshops have been held yearly since then and have been a place where developers of leading edge software could meet and talk to each other about their activities related to Earth Observation and Geospatial data and services. In 2003 several individuals who were long term CEOS and EOGEO Workshop participants decided to form a non-profit organization named after the workshop series. Thus EOGEO, the organization, was begun. EOGEO has been in existence for about 2 years as a non-profit now. This talk will provide more details about the history of the workshops as well as more information about what the EOGEO organization is doing.

Data Access Systems from the U.S. Geological Survey (PPT) by Pericles Nacionales — last modified 2005-11-19 16:26

Author: John Faundeen, USGS Abstract: This presentation describes the characteristics of the numerous standards-based systems developed to provide access to the voluminous amounts of earth science data that the U.S. Geological Survey manages for the Public good. Scanned aerial photographs, elevation models, and satellite imagery, some dating from as early as the 1930s, provide researchers and the public with great tools with which to compare current data for purposes as diverse as detecting changes in the landscape and mapping urban development to disaster recovery and real estate planning. The systems designed to provide useful and efficient access to those data rely upon standards, both open-based and de facto. Federal Geographic Data Committee, Open Geospatial Consortium, NASA Directory Interchange Files, and Environmental Systems Research Institute (1) shapefile standards are utilized to serve our large customer base, which includes the international Committee on Earth Observation Satellites and the Nations satellite archive users through the National Satellite Land Remote Sensing Data Archive.

EoGeo: Use Cases and the Information Models for Open SDI (PPT) by Pericles Nacionales — last modified 2005-11-19 16:26

Author: Joshua Lieberman Abstract: An exciting area of development for open-source geospatial components is the configuration and distribution of integrated packages as spatial data infrastructure (SDI) nodes. This has the potential to vastly increase SDI participation among local agencies and NGO's. Consideration of how these nodes may be used and what information needs to be managed by them can guide how best to adapt and integrate available open-source components towards this goal.

An Introduction to the GeoTools Library and the Family of Related Projects (SXI) by Pericles Nacionales — last modified 2005-11-19 16:26

Author: James Macgill, Penn State University Abstract: GeoTools is an open source Java GIS toolkit. It provides the functionality required to support implementation of many key Open Geospatial Consortium (OGC) specifications. This talk will provide an introduction to the GeoTools library, as well as providing an overview of the relationship between the library and three projects which leverage it as a core for their functionality, namely GeoServer, uDIG and GeoVISTA Studio. Geotools maintains an open development process, with public collaboration on new ideas. Project communication is open to all, indeed the developer pool is distributed across universities, government agencies, commercial companies and non-profit organizations around the world, the final part of this presentation will reflect on challenges of running such a distributed project, the strategies which have been employed to keep development moving forwards, in particular it will highlight the role that standards have played in keeping the community focused.

The ICEDS OGC-compliant Server for Interactive Global Mapping and Data Delivery Using SRTM and Landsat Data (PPT) by Pericles Nacionales — last modified 2005-11-19 16:26

Authors: Morley J.G., Muller J.P., Gil N., Willis I., Giovando C., Greening, O. Abstract: The Integrated CEOS European Data Server (ICEDS) has been funded by the British National Space Centre (BNSC) as a prototype within the Committee for Earth Observing Systems (CEOS) CLASP activity. Particular aims have been to: 1. exploit Open Geospatial Consortium (OGC) technologies for interoperable map and data serving; 2. serve datasets, particularly global 3 arc-second (ÿ90m) Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) and for Europe and Africa, 1 arc-second (ÿ30m) Landsat TM data; 3. provide a portal website giving access to the served data along with cascaded maps and images from other Web Map Servers; 4. provide software scripts and a document describing the data processing and software set-up methods developed during the project. ICEDS is publicly accessible both through its Web portal (http://iceds.ge.ucl.ac.uk) and by Web Mapping Service (WMS) and Web Coverage Service (WCS) connections. The SRTM data currently served from ICEDS is the unedited dataset from JPL distributed by USGS. In order to be served on the ICEDS web portal and through a WMS, the SRTM data were colour hill-shaded with oceans and principal inland water bodies masked out. The decision was made not to attempt to fill the gaps in the unedited data but to highlight these regions as a form of qualitative validation. As a result of the hill-shading and masking process, unfilled pixels in the DEM appear as bright red in the final hill-shaded images. The highlighting of unassigned pixels in the SRTM DEM in association with the Landsat TM mosaics has proved of great use in validating the dataset. The ICEDS WCS allows direct connection to the source data – in this case, the unedited SRTM elevations and individual, unstretched but mosaiced Landsat bands (1,2,3) as seamless layers. The WCS can be accessed from links in the Web portal for download of source data as GeoTIFF files. An interactive demonstration of the web site and its utility for data exploration and validation will be given if facilities permit.

GeoNetwork OpenSource (PPT) by Pericles Nacionales — last modified 2005-11-19 16:26

Author: Jeroen Ticheler, Food and Agriculture Organization of the United Nations Abstract: In 2001, the Food and Agriculture Organization of the United nations (FAO) set up FAO GeoNetwork (www.fao.org/geonetwork), a facility that provides various services, such as a global library for geospatial data; a metadata catalogue; a system for searching, editing and publishing geospatial information; as well as information on how to integrate geospatial data from various sources on the Internet. The United Nations World Food Program's Vulnerability Analysis & Mapping branch (WFP-VAM) soon joined FAO in the further development of GeoNetwork through formulation of additional requirements and through co-funding. Early 2004 the United Nations Environment Program (UNEP) joined FAO and WFP in the development, further strengthening the GeoNetwork OpenSource software and improving standardized access to spatial data and information. GeoNetwork OpenSource is released as a standards based Free Open Source Software, implementing OGC and ISO TC211 standards. This means that users are able to use, modify and redistribute system source code software without significant restrictions, thus benefiting communities and organizations in countries with limited financial resources and often inadequate internet access. Recent work has resulted in GeoNetwork version 2 and has generated interest from other related open source software projects. Efforts are underway to work on effective integration of GeoNetwork with these projects through the OpenSDI initiative. The GeoNetwork opensource software is maintained at http://sourceforge.net/projects/geonetwork.

Development of OGC Compliant Prototype Systems to Promote Application of EO Satellite Data by Pericles Nacionales — last modified 2005-11-19 16:26

Presenter: Shinobu Kawahito, JAXA/RESTEC Abstract: It is often the case that, for practical applications, a given type of Earth Observation satellite data needs to be combined with other types of Earth Observation satellite data, as well as with non-satellite geospatial data such as administrative thematic maps and statistical maps. Those data resources are generally owned and archived separately. JAXA (Japan Aerospace Exploration Agency), together with other data holders, the agricultural ministry and universities in Japan, are developing OGC compliant prototype systems to cultivate services which use EO satellite data and to develop methods to utilize archived geospatial data. In this presentation, the prototype systems, which are (1) a land condition information providing system for environmental change and disaster mitigation purposes for local areas in Japan, (2) a (fire) hotspot, vegetation, and inundation monitoring system for agricultural purposes for the Asian region, will be described.
