he is the only one in many cases who can bring to bear the local knowledge,
expertise and experience that is so vital to the successful application of
these special tools of management.
Despite the lack of success with ERTS data in this project, its poten
tial capability in the near future should not be overlooked. It should be
emphasized again that its applicability was tested under only one set of con
ditions and only the most rudimentary techniques of data handling, enhancement
and analysis. This method of approach was in part unavoidable due to the lack
of funds and facilities to accomplish more sophisticated forms of data analysis
and in part intentional in that we wished to determine the lowest common denom
inator in terms of ERTS data analysis equipment and techniques which might
make it possible for a relatively large number of resource management people to
utilize it successfully at a reasonable cost.
ACKNOWLEDGEMENTS
This project was financed jointly by the Montana State Office of the
Bureau of Land Management and the University of Minnesota College of Forestry.
The authors wish to thank the BLM personnel in Montana (and there were many)
whose interest, enthusiasm, ideas and unselfish effort made possible any suc
cesses this effort will enjoy. In particular, we wish to express our apprecia
tion to Montana State Director Edwin Zaidlicz and Mr. James Linne of the
Washington Office, BLM.
We drew very heavily both for encouragement and technical guidance from
both the literature of, and contacts with, a number of investigators in related
areas. We wish particularly to acknowledge the following persons in this re
gard: Mr. Robert C. Heller and his staff at the USDA - Forest Service Remote
Sensing Laboratory in California; Dr. Richard S. Driscoll, Principal Plant
Ecologist, USDA - Forest Service in Colorado; and Mr. Victor Zsilinszky,
Ontario Centre for Remote Sensing, Canada.
