(5) Aerial imagery should be considered for use in obtaining subsample data extending the available "ground sample" information for some parameters. These data can be very valuable for building models to stratify satellite remote sensing data into classes of interest, to verify the accuracy of those strata, and for direct use in the estimation of area and other forest parameters. (6) Pursue change detection and labelling research, especially to support classification of more subtle change (c.g., thinning, certain types of forest damage) using remote sensing data. Key topics include band calibration methodology, forest canopy/spectral reflectance modelling, image segmentation for change, simultaneous use of different sources of data for the same location, ground measurements related to change phenomena seen in images, and efficient procedures for producing forest parameter change estimates with a remote sensing-aided system. This work should improve performance and understanding in all areas of the system. (7) It will be important to join with the Canadians and others in evaluating the added information content and practical applicability of radar data. (8) The utility of all data and information is likely to be enhanced through the use of geographic information systems. For example, cover type or damage assessment results derived through the Swedish NFI could be improved in identification detail and/or spatial accuracy when combined with National Board of Forestry compartment map data, or when combined with private company stand management data. (9) A significant field data set will be required to support this work. In this context, the existing NFI data set represents an extremely valuable and rare resource. It should be supplemented in a properly designed way, if possible through field data collected by other organizations in order to minimize cost. (10) It will be important to listen to, cooperate with, and, in some cases form well-coordinated partnerships with other groups in order to develop a flexible and effective remote sensing-aided Swedish NFI. CONCLUDING REMARKS The program to incorporate remote sensing in the Swedish NFI is scheduled to begin during the summer of 1990. A project will be initiated to evaluate clear-felling monitoring techniques for NFI use based on satellite data. The project will also prepare a program for the longer term effort to implement remote sensing for the fuller range of topics discussed above. It is expected that the complete program will be implemented in stages, and will take at least 10 or more years to be realized. AKNOWLEDGEMENIS The authors would like to thank the faculty and staff of the the Swedish Faculty of Forestry, Departments of Forest Survey and Biometry and Forest Management for their review and input during the Project. Similar thanks also goes those at the Swedish Committee on Forest Remote Sensing, the Swedish Space Corporation, the University of Helsinki Department of Forest Mensuration and Management, the Finnish Forest Research Institute, the Danish Bureau of Land Survey, and the Danish Technical University of 415
