A. Overall S;tatus
1. Atlanta, Georgia - forest inventory site (512)
No SL-2 or SL-3. overflights have been accomplished over this site.
We are making preparations to man this site and use the silicon vidicon
airborne system as soon as we can determine the expected dates of SL-4
overpasses.
2. Black Hills, South. Dakota - forest stress site (312)
All of the requested photographic products from SL-2 have now been
received, with the final shipment of 9 1/2-inch color enlarged transparen-
cies rrom the earth terrain mapping camera (S-190B) arriving during mid-
November.
A photographic image analysis plan has been formulated based on
the coverage received over the Black Hills on June 9, 1973. This plan in-
cludes the creation of color composites (in negative form) from the S-190A
imagery. The color negatives will in turn be enlarged for human photo in-
terpretation. Preanalysis viewing of all photographic imagery indicates
some of the proposal objectives can be attained even though the imagery
was obtained at a poor time of year. Had SL-3 performed as planned during
September, we believe the proposal objectives would have been achieved
with great success.
Our requirements for processing 24-channel scanner data (Mission
247) were submitted to the Data Management Section. Although we will not
receive some of the products requested, subsequent negotiations provided
a satisfactory solution for our needs. Based on our negotiations, we will
actually receive one copy of each of the channels imaged [for three flight
2Lines) on 9 1/2-inch black-and-white transparency film. A separate copy
of the same imagery in negative form woulld have been helpful. In addition,
the Dats. Management Secti.on has agreed to provide two 3-color enhancements
of the MSS da.ta. This will be undertaken as a one-time joint study so as
to uti.ize some of the quantitative target radiance data we collected at
the time of the C-130 flight on September 1.7, 1973.
3. Manitou, Colorado - range inventory site (313)
All aircraft support data, Missions 238, 239, and 248, have been
received and indexed. Photographic imagery from Missions 239 and 248
(RB-57) representing selected subsets of detailed analysis and interpreta-
tion have been chosen and preliminary interpretations made.
No SL-3 data, the data-take pass August 4, 1973, has been received.
Preliminary linear regression models have been developed to relate
ground-measured plant community parameters, i.e., percent live foliage
cover, percent bare ground, and percent plant litter, to those same
parameters measured photogrammetrically in large-scale (1:600) color and
color infrared aerial photographs. Correlation coefficients using the
color infrared photographs are higher than those derived using the color
photographs. We need to increase measurement precision on the photographs
to improve the correlation coefficients before a sampling model for smaller
scale photographs and the Skylab photographs is developed.
B. Recommendations Concerning Decisions Required to Ensure Attainment
of' Experiment's Scientific Objectives
1. Black Hills, South Dakota - forest stress site (312)
We are still waiting word from the PIMO on the status of the SL-2,
S-192 MSS tapes. We would like to receive the MSS tapes as soon as pos-
sible so that we may begin processing the data through our subcontract with
the University of Kansas. Further delays beyond January 1 will necessitate
subcontract amendments and also will likely result in a request for a time
extension on our contract expiration date.
2. Manitou, Colorado - range inventory site (313)
Until we have opportunity to examine and compare SL-3 data with
SL-2 data, and until we have definite knowledge of the kinds and quality
of SL-3 data, we have no specific recommendations for the Skylab range
inventory experiment.
3C. Expected Accomplishments
Manitou, Colorado - range inventory site (313)
We should be able to make preliminary statements regarding pla.nt com-
munity classification by stereoscopic interpretation of SL-2 photographic
products compared to the same kind of interpretation using the support
aircraft data from Mission 239. If SL-3 products are received, we will
make preliminary statements on temporal changes in plant communities
interpretable using SL-2 and SL-3 products.
D. Significant Results, Practi;al Applications, and Operational Problems.
All sites - none at present.
E. Summary Outlook
Ali. sites - no changes in our statement of work at present.
P. Travel PLans - November 16 to December 15, 1973
1. Manitou, Colorado - range inventory Site (313)
Drisco11 plans to go to 'erkeley, CA, during the period. 11/26-
11/30/73 to do work on the I2S system using the black-and-white SL-2 S-190A
products and to do enlargements of the color and color infrared SL-2 S-190A
products .
