RE: Type I Report No. 2 ('"etermination of Species"
Proposal No. 327-Lowe), for the second two month period
"The objective of this study is the determination of specific
spectral signatures for dominant desert scrub plant species (and
their soil surface backgrounds) with use of overf ight coverage
as an intermediate link between permanent ground truth points and
satellite imagery."
Our present status, is as follows:
1. We have changed our photographic equipment from a 35mm to
a 70am film format. Our original instrument package included a
mount of several 35mn cameras which was hand held. All cameras
were triggered simultaneously to produce a multi-spectral image
set. This has proven unsatisfactory for two reasons:
a. At our close working range to the subject plants,,; the
parallax distortion becomes significant.
b. 35mm film proves to be of insufficient size and quality
for analysis with the E.R.T.S. additive viewer.
For these reasons, we have changed to one Hasselblad single lens
reflex camera, mounted on a sturdy tripod. Using interchangeable
camera backs and sliding filters, five different film-filter
combinations are sequentially exposed for each subject. This
provides a set of 70mm multispectral images which avoid parallax
distortion by having all been exposed through the same lens.

This change in format has not necessitated the purchase of additional
cameras, as the Hasselblad equipment involved is in-house property,
on loan to the project. Also, arrangements to process the 70mm
film required only slight modifications of facilities already
available, and can and will proceed on or off campus within the
limitations of the project budget and design.
2. The spectrometer which was to be provided by A.R.E.T.S. (as
indicated in Attachment A, page 2 in our proposal) has been received
by that office, and is now available to us.
3. From the initial analysis of E.R.T.S. imagery for our area, it
appears that it may be necessary to use photo-enhancement techniques
to compensate for the low contrast of the desert. We have begun
developing procedures for doing this.
4. Due to variations in atmospheric conditions and film processing
from overflight to overflight, particularly with U2 intermediate,
a reference area of known spectral reflectance could be included
in the study Site if film densities on the images from different
dates are to be compared. Furthermore, this reference area should
be large enough for its density to be isolated and determined on
the E.R.T.S. image.
We are presently testing the feasibility of doing this with the
tailings of the Silverbell Copper Mine near our Site. The tailings
are a by-product of the mining process in which a gray sand
forming a flat smooth surface of about 800 acres results. We have
begun taking readings off of this surface with the spectrometer
during E.R.T.S. overflight, and hope to be able to use this data
to calibrate the resultant imagery with ground truth values.

C. H. Lowe and D. M. Slaymaker
"The objective of this study is the determination of specific
spectral signatures for dominant desert scrub plant species
(and their soil surface backgrounds) with use of overflight
coverage as an intermediate link between permanent ground truth
points and satellite imagery."
1. We are now into the last phase of our project in which our
results will be analyized and a final report prepared. In order
to extend our funds to cover the revised completion date of
December 15, 1973, the size of our staff has been reduced and
further field work terminated. The analysis of present data is
on schedule and we forsee no problems in meeting our present
deadline.
2. We have been asked to present a paper at the Fourth Annual
Symposium on Remote Sensing at the University of Arizona. Nov.
14 to 16. The outline and visual material will be similar to
those presented for the recent Panel Review.
3. All materials necessary for the completion of this project
have been received and we require nothing further at this time.

RE: Type I'Report No. 1 ("Determination of Species"
Proposal No. 327-Lowe), for first two month period
executed October 4, 1972.
"The objective of this study is the determination of specific
spectral signatures for dominant desert scrub plant species (and
their soil surface backgrounds) with use of overflight coverage as
an intermediate link between permanent ground truth points and sat-
ellite imagery."
1. Mr. Dana M. Slaymaker has been hired as chief administrative
assistant for this project. It is requested that all future cor-
respondence, information, or material from standing orders be sent
directly to him (rather than to the Principal Investigator,. Dr;
Charles Lowe) at the following address:
The University of Arizona

2. Materials to date from standing orders have been received and
catalogued. Work has begun to generate a data analysis plan with
equipment available through the Offices for Arid Lands Studies.
3. Necessary film for ground truth has been ordered from a local
representative of Kodak Corporation, and is expected within one month.

4. Geological andsoil survey maps of the primary test site in
Avra Valley, Arizona, have been ordered; vegetation type and cov-
erage information is being acquired from several sources.
5. Miscellaneous equipment has been secured and arrangements made
for camera and equipment maintenance.
At present, initiation of the spectral signature determination is
impeded by the lack of a portable spectrometer, which was to be
added to our instrument package of two 35mm cameras and a hand-held
radiometer. As indicated in attachment A (2nd page), the spectro-
meter is to be provided by the A. R. E. T. S. through the Office of
Arid Lands Studies at the University of Arizona. O. A. L. S. has
the unit on order, but has not yet received it from the manufacturer.
Dr. Larry K. Lepley, A. R. E. T. S., Project Manager, is constructing
another portable spectrometer as an in-house project. It is antici-
pated that one or the other will be ready by January or February of
1973 forthcoming.
