FIRST QUARTERLY REPORT, 28 October- 1976

o 	 Progress has been made as shown by the attached list of publications.
> _	 (	 ;^ ►= N Strictly, However, the first quarterly report is not due because magnetic
" °tapes were not received from NASA although re;uested in the original
e	 ^^ v	 iadpllcatlon. Some ,.-here along the litre the request for tapes got lost and(")
	 z a "i removed from the request fer data products. Twelve only film chips ►•;ere
z W LL.	 ``'received in 1976 from Sioux Falls but k . ere unsatisfac t 	for the work.
< U0 o	 Accordingly eleven tapes r ,ere purchas ed from the U	 + after inspect-
ion of the browse file at Technical
	
and Field S.;rveys,	 .nd their cost was
an unexpected budget	 item.	 They arrived on 28 April	 1976 but were on a
new format of 1600 bits/inch	 instead of the expected 800 b.p.i. 	 This
= necessitated ordering and installing new col-puter hardware 	 in order to
read the tapes.	 The purchase and installation tras not completed till
_- August	 1976.
-_ Oy the time we could read the tapes, a significant backlog of processing
x	 -^  had built rrp	 in liineral	 Physics	 Division	 for other investigators	 beside our-
o	 K 
s selves.	 To clear the backlog the installation has been put on shifts.
'= Processing of the New England tapes is underway.
A new problem has emerged in than the film-writing system has to be
matched to the colour compositing system at Aerial 	 Photographs Pty Ltd in
,•	 __, Melbourne.	 Dr.	 Huntington has	 found one solution, % .rhich	 is	 to write 70
- mm positive chips of the 4 banns, inount them in the projection viewer,
obtain a correct colour balance,	 photograph the result in 35 cnr, 	 thus
obtaining a transparency sho:•jing the colour balance required.	 The three
bands required are then re-written from tape onto 9" x 9"	 format and sent
to '.elbourne along with the transparency. 	 This system produces results at
a cost of about 4 hours extra time on the film-writing computer plus pre-
liminary experimentation in the projection viewer, colour 35 mm photography
and processing.
After discussions with Dr. A. Green we have decided to short-circuit
this process in the interests of speed, but we expect the colour balance
to be nasty. The images will be written for maximum contrast in black and
white, as determined by statistical analysis of the ''apes and written as
negatives. The site photographer will produce contact positives of matched
density which r g ill be sent for colour compositing. A permanent solution
seems to require matching the computer processing to the colour processing
and is under investigation by Green, ;iuntington, and Gale Morton of Technical
abd Field Surveys in Sydney.

2In the meantime a lot of other geological work has been completed on the
assembly of existing information (ground-truth). Pri ►its of about 300
geological maps on several different scales, all detailed, were made and
coloured. Structural data were extracted avid compiled on transparencies
to a common scale of 1 to 250,000. The Armidale office of the Ceological
Survey of New South Males has compiled another transparancy sho:4ing over
600 mines and prospects in the New England region. Two student theses on
the Demon Fault have been completed.
The team has been joined by A. ,)ones whose main objective has been the
'	 production of land cover maps from the EROS Data Center images at 1:1,000,000
and 1:250,000. Lithographic film has been used on Elands 5 and 7 to produce
high contras t_ negative and positive images of the same scene. These have
been reproduced cheaply in vari c US col ^ :,!r coma! inatiors on di?_zn 11; :, the
most favourable combination being as follo;.s:-
Band 5	 Positive	 Magenta
Band 5	 Negative	 Yello:i
Band 7	 Positive	 Green
Band 7
	
Negative	 Cyan.
An example of a LANDSAT-1 scene of the Armidale area is attached to
this report. Further details of the method will appear in the Bulletin of
the Remote Sensing Association of Australia and Photogrammetric Encineerinr
and Remote Sensing.
The resolution of the bulk processed scenes makes field checking rather
difficult and this is awaiting the deliv?ry of computer enhanced negatives
from C. S.i.R.ii. I.Ath these it should be possible to analyse each image
pixel by pixel v;hich will make checking of the land cover map more reliable.
As an interim measure a land cover map has been produced for the New
England Region from bulk processed images purchased from the EROS Data Center.
This niap viill be published early in 1977 in a Regional Atlas of New England
being prepared by the University of New England.
The diazo processor has also been used for the production of false colour
composites which compare very favourably with photographically produced colour
prints and transparencies.
Jones is now visiting the University of Wales and his further work will
be in abeyance until August 1977.
Professor R. Green has also joined the team. He and p is students have
built a vehicle-borne magnetometer for the work and are doing magnetic and
gravity surveys across clusters of plutons and across the hlooki, Peel and
Demon faults. Some of the results have been written up in theses but are
not yet published.
