Extractions: 1. INTRODUCTION The Landsat Pathfinder Humid Tropical Forest Inventory Project is a multi-agency effort to acquire high resolution satellite data for the humid tropical forests of the world in an effort to map deforestation rates and provide timely and accurate data to support global change research in the area of carbon cycle models, and related policy efforts including the Intergovernmental Panel on Climate Change and the Framework Convention on Climate Change. The effort also supports and couples to other initiatives including the International Geosphere Biosphere Program, including the Land Use and Land Cover Change Core Project and START. The project focus is tropics-wide and this contributes to that effort by focusing on activities in Southeast Asia. Therefore deliverables are divided into two categories: (a) those focused on continuation of work in Southeast Asia and (b) those expected from the full-up project. 2. OVERVIEW OF RESEARCH OBJECTIVES

Extractions: Advances Deforestation Mapping By Walter Chomentowski, Bill Salas , and David Skole . Chomentowski and Salas are research scientists and Skole is an assistant professor with the University of New Hampshire Complex Systems Research Center, Institute for the Study of Earth, Oceans, and Space, Morse Hall, Durham, NH 03824-3525, USA. The Landsat Pathfinder project is demonstrating the use of Landsat data for global change research and monitoring the world's forest resources. One of the five Pathfinder projects initiated by the U.S. National Aeronautics and Space Administration (NASA), Landsat Pathfinder is a first step toward establishing a global monitoring system using high-resolution satellite imagery. The imagery will be stored, managed and analyzed with a GIS. Pathfinder is part of NASA's response to the requirements of the U.S. Global Change Research Programthe centerpiece of which is the Earth Observing System (EOS) satellite series. Scheduled to begin operation in 1998, EOS will transmit as much as two terabytes (2,000 gigabytes) of Earth data each day. Pathfinder's mission is to explore the data needs of scientists studying global change and prepare for the massive EOS data stream. Some researchers estimate the global deforestation rate has more than doubled since the early 1980's; others say it has increased by only 50 percent. The Landsat Pathfinder project will help scientists better quantify estimates of land use/land cover change in the world's tropical forests. Above, the project's study area is shown in red. The Amazon/Orinoco river basins, central Africa and southeast Asia contain 75 percent of the world's tropical forest.

Salas are research scientists at the Institute for the Study of Earth, Oceans, and Space, University of New Hampshire, Durham, NH 03824. A. D. Nobre is a scientist at the Instituto Nacional de Pesquisas Amazonas, Manaus, Amazonas, Brazil. Tropical deforestation is an important component of global change; it has a large influence on hydrology, climate, and global biogeochemical cycles (Crutzen and Andreae 1990, Houghton 1991, Houghton and Skole 1990, Salati and Vose 1984, Shukla et al. 1990). The Brazilian Amazon region is the largest intact tropical forest in the world. Brazil has the highest deforestation rate in the world, according to some estimates; deforestation rates may be 1.5 - 2.0 x 10(6) ha/yr (FAO 1993, Myers 1991, Skole and Tucker, 1993). Understanding of tropical deforestation, an important aspect of global change, is inadequate for two reasons: a lack of accurate measurements of its rate, geographic extent, and spatial pattern and a lack of insight into its causes (Skole in press). It seems obvious that tropical deforestation is the consequence of a variety of interrelated social, economic, and environmental factors. Yet, interpretations of how these factors interact to stimulate deforestation vary widely. Some interpretations focus chiefly on population growth, whereas others regard institutions as the main determinant (Allen and Barnes 1985, Browder 1988, Bunker 1984b, Meyer and Turner 1992, Moran et al. this issue, Rudel 1989, Sanderson in press).

Extractions: CIESIN Thematic Guides NASA initiated the Landsat Pathfinder data set in 1991, with the intent of reconfiguring selected portions of the global Landsat data archive to optimize use of Landsat data for global change research. The historical archive consists of 21 years of Landsat Multispectral Scanner (MSS) data at a spatial resolution of 80 meters, and 11 years of Landsat Thematic Mapper (TM) data at a spatial resolution of 30 meters. The Landsat Pathfinder Program Definition Phase Report [not yet available] provides a complete description of the Landsat Pathfinder concept and component activities (publication expected late 1994). The Landsat Pathfinder data set currently includes three component efforts. The first is the Humid Tropical Forest Inventory Project , which is associated with developing a complete three-epoch, consistently processed Landsat database for the humid, tropical forests of the Amazon Basin, Central Africa, and Southeast Asia. The three epochs are generally the early- to mid-1970s, mid-1980s, and the early 1990s. For each epoch, a set of Landsat scenes will be selected on the basis of minimal cloud cover and acceptable data quality to provide complete coverage of the humid, tropical forest regions. This data set is intended for evaluation of the rate and extent of tropical deforestation. The second effort is the North American Land Characterization (NALC) Project, which will bring together three epochs of historical Landsat MSS data in a standard configuration for much of the land surface of the North American continent, according to the Environmental Protection Agency research brief (1993)

Sadowski Norm Roller John E. Colwell Environmental Research Institute of Michigan (ERIM) Consortium for International Earth Science Information Network (CIESIN) ABSTRACT Successful implementation of studies addressing the human dimensions of global change will pose major conceptual and methodological challenges for the social sciences. The Landsat Pathfinder Program will offer significant benefits for meeting the challenges facing social scientists studying global change. The benefits include: (1) assisting the development and implementation of a global perspective for research; (2) aiding the coordination of interdisciplinary research; and (3) aiding the longitudinal studies of global environmental change. INTRODUCTION There is increasing awareness that the collective actions of humanity are capable of affecting the Earth system and its processes. Humanity, in turn, is capable of being affected by changes in the Earth system induced by these effects. The nature of humanity's actions at different levels in society (local, national, and international) and in the fabric of society (for example, its social, economic, and political structures and institutions) comprise what are commonly referred to as the human dimensions of global change.

It's primary goals were to determine how the boreal forest interacts with the atmosphere (via the transfer of gases and energy), how much carbon is stored in the forest ecosystem, how climate change will affect the forest, and how changes in the forest affects weather and climate. The BOREAS Follow-on is a collection of data sets containing additional information from the BOREAS Project. Forest Ecosystem Dynamics - The Forest Ecosystem Dynamics Program (FEDS) is concerned with modeling and monitoring ecosystem processes and patterns in response to natural and anthropogenic effects. The overall objective of the FED project is to link and use models of forest dynamics, soil processes and canopy energetics to understand how ecosystem response to change affects patterns and processes in northern and boreal forests and to assess the implications for global change.

Extractions: LANDSAT MSS Mosaicking Although remote sensing satellite imagery has been widely available for over 20 years, the steps toward operational use of it have been slow. In the case of preprocessing, operational systems still address only scene-based correction issues. Geometric rectification has matured to the state where sophisticated spacecraft modelling and control point acquisition techniques are sufficient to ensure routine, sub-pixel correction accuracy for imagery from high resolution sensors such as those carried on the LANDSAT and SPOT platforms. In the case of scene radiometry, sensor-related corrections are routine; however, atmospheric correction is still viewed as a complex post-processing step. Current applications requirements, particularly in the area of environment monitoring, necessitate an expansion of our operational preprocessing systems. Monitoring in many instances requires integrated data sets of large geographic coverage which in turn can span many conventional remote sensing scenes. Preprocessing must therefore be broadened to encompass multi-scene fusion issues. In the case of imagery from the

October 1997 The Committee on Earth Observation Satellites (CEOS) was established to provide a forum for communication, cooperation, and coordination of earth-observation programs. Besides its member space agencies, CEOS also includes a number of officially recognized affiliates - organizations whose primary interest is the use of earth-observation data, or the information derived from earth-observation data. CCRS is a CEOS affiliate, while the Canadian Space Agency (CSA) is a CEOS member. At the plenary meeting in Canberra, Australia in November, 1996, CEOS decided that the job of coordinating earth-observation programs could best be accomplished by establishing a small number of pilot projects to address issues of great concern to the majority of CEOS members and affiliates. CEOS established a Strategic Implementation Team (SIT) to oversee the establishment of pilot projects. In February, 1997, Canada was honoured to be chosen to lead a pilot project (one of six) called Global Observations of Forest Cover (GOFC). Reasons for this choice included the important role RADARSAT can play in monitoring forests worldwide, Canada's excellent track record in the application of remote sensing to forest land management, and the importance of forests to Canada and Canadians. Several international efforts have provided valuable data for forest monitoring, some of which are listed in Table 1. The global forest pilot project will bolster these efforts by providing an environment under which
