.. 1\ Q 4.4
Proposal No.: SR-273)
b. GSFC ID No.: IN-084
c. Statement and explanation of impedance:
Imagery has been received for only a few test sites for which data
was requested, these being San Francisco, Phoenix and Tucson. Large
quantities of imagery have been received for areas not part of any
specified test sites while available data for most mandatory and
desirable test areas have not been received. This discrepancy
between receipt of non-requested coverage and no receipt of requested
coverage has been due to programming errors for data requirements in
the computer system at NDPF. This problem has been brought to their
attention and a new listing of data requirements and test site co-
ordinates has been submitted for reprogramming. Imagery for remaining
test sites has been back-ordered.
In addition, the work statement of ERTS Experiment 273 (GSFC ID No.
IN-084) is still on record as that appearing in the Memorandum of
Understanding between NASA and USGS which is based on the initial
proposal but which was subsequently ievised. The revised work state-
ment omits certain tasks in keeping with the reduced budget and
suggested time frame. An Ammendment of the new work statement is in
preparation.
d. Accomplishments during the reporting period and those planned for
the next periodt
Pursue acquisition of reproduction of 1972 aircraft ERTS underf1ight
photography which has already been flown, plus acquisition of air-
craft,ERTS underf1ight photography for additional urban test sites.
This photography is essential for the change detection aspect of
. .
the experiment as well as for the evaluation of the ERTS imagery
itself. Pursue acquisition of ERTS imagery over urban test sites.
Meanwhile, analyses of 1970 urban land use from 1970 census contem-
poraneous aircraft photography is progressing. Land use maps,
mosaics, and census overlays for the two largest urban test sites
are nearing pub1~cation readiness. Area analyses are underway for
San Francisco, Washirigt6n, Phoenix and Tucson.
One set of Computer Compatible Tapes for one ERTS frame of San
Franc·:L,sco was ordered and del ivered.
e. Scientific results and practic'a1 app1 ications (Category 2E).
Oral and written presentations listed under (f) include mention of
likely applications of comparative urban area analyses using remote
sensors aboard aircraft. Some applications and preliminary evaluations
of ERTS imagery are also listed.
Analyses of cost benefits are planned, but none have been undertaken
to date.

po1itan Region," by James R. Wray, presented at a meeting of the
American Society of Mechanical Engineers at Anaheim, September 12-13.

Columbus, 0hio, October 11-13. A similar version of this paper was
presented at the University of Michigan Eighth Symposium on Remote
Sensing, and will appear in the Proceedings, Ann Arbor, October 2-6~
g. Recommendations for improvement:
Recommend (1) collateral reseprch in automatic pattern recognition
of urban land use and land use change; (2) preparation of proce-
dural manual for producing comparative urban analyses from high
altitude photography, and 0) development of urban spatial growth
model from comparative urban land use studies produced by this
experiment. Proposals for these efforts have been submitted to,
and accepted for funding ~y, the EROS Program Manager.
h. Changes in standing order forms:
A change from receipt of RBV imagery to MSS imagery was affected
during the last reporting period. Since,then, changes in the MSS
bulk-processed products have been requested. The following 3 lists
specify the products requested but not received, as specified in the
j
original product order (except for the change from RBV to MSS), those
products received but not requested in the original product order,
and those products requested in the revised product order, already
submitted, for all future shipments of data.
