Type I Progress Report
ERTS-1
a. Title: Appraising Changes in Continental Migratory Bird Habitat
ERTS-A Proposal No.: SR 255
b. GSFC ID No. of P.I.: IN 051
c. Statement and explanation of any problems that are impeding the
progress of the investigation:
Delays in the receipt of imagery and digital tapes is
seriously threatening the timely conclusion of this program.
Our previous Type I Progress Report (dated 1 September 1973)
has discussed this problem. The following is a summary of
the situation.
We have had in effect a standing order for black and white
MS) imagery f r data centered approximately at coordinates
47'40'N by 99U40'W. When instituted this standing order
was effective for the period May through 6 October 1973.
Throughout this period our requirements for imagery should
have been satisfied.on the 18 day cyclic schedule of 15
May, 2 June, 20 June, 8 July, 26 July, 13.,August, 31 August,
18 September, and 6 October. To date we can account for
imagery for 15 May, 2 June, 20 June, and 8 July. (Imagery
for these dates has either been received or it has been
excluded due to an excess of cloud cover.) Data which should
have been collected on either 26 July or 13 August is very
significant to this program because it documents conditions
at the peak of the waterfowl brooding season. Our current
information indicates that no site data for these dates has
been entered into the NDPF User Services system. As a
result we are unable to evaluate the quality of that data
let alone order the CCT's for subsequent machine processing.
We have now recognized that it may be necessary to utilize an
alternative data set and therefore on 1 October we placed
an order with User Services for data of 7 July 73. This
data will not be centered on our site and the data will
temporally two to three weeks premature. However,
the data will suffice in view of the protracted delays
apparent with regards to data of either 26 July or 13
August. It is also significant to note that CCT's for
site coverage of 15 May were ordered in mid June but
were not received until 13 September- approximately a
three month turn-around time. Processing of this May
data was deferred until receipt of the July data so that
the two sets could be processed in tandem for reasons
of economy and efficiency.
d. Discussion of the accomplishments during the reporting period
and those planned for the next reporting period:
Progress on the program was suspended pending avail-
ability of a comprehensive May and July (or August)
data set. The CCT's for 7 July 1973 have just been
received and processing will commence at once. Pro-
cessing and analysis is expected to require three
months of effort. As a result, we realize that a
contract extension will be necessary and action for
requesting such an extension will be initiated. We
anticipate a contract extension of three months or
through 31 March 1974.
e. Discussion of significant scientific results and their rela-
tionship to practical applications or operational problems
including estimates of the cost benefits of any significant
results (to be prepared in scientific abstract form of 200
words or less):
None
f. Listinlg of published articles, and/or papers, pre-prints, in-
house reports, abstracts of talks, that were released during
the reporting period:
None
g. Recommendations concerning practical changes in operations,
additional investigative effort and/or results as related
to a maximum utilization of the ERTS system:
We recommend a no cost contract extension for this
task and for the subcontract with the Environmental
Research Institute of Michigan.
h. A listing by date of any changes in Standing Order Forms:
None
i. ERTS Image Descriptor forms:
None
j. Listing by date of any changed Data Request forms submitted
to Goddard Space Flight Center/NDPF during the reporting
period:
None
k. Status of Data Collection Platforms (if applicable):
