SECTION I
INTRODUCTION
During the year of 1977, the Brazilian Institute for
Space Research (INPE) is continuing its active participation in the
LANDSAT Program. The Image Production Center is regularly acquiring,
processing and disseminating LANDSAT 2 data besides keeping its
production for LANDSAT 1 data.
The whole system is favorably adapting itself to the
changes mentioned in the system status report presented during the last
LGSOWG meeting at Ottawa, Canada.
In fact this report is to be considered as an updating of
the last report, now for the period from October 1976 to February, 1977.

2.3 - OPERATIONAL STATUS OF FACILITIES
2.3.1 - CUTABA TRACKING AND RECEIVING STATION
Recorded LANDSAT-1 MSS data (from May 1973 to February 1977)
= 1544 orbits.
Recorded LANDSAT-2 MSS data (from January 1975 to February 1977
= 317 orbits.
. Quick-Look imagery production reassumed at the end of February 1977.
Data acquisition of LANDSAT-2 (MSS data) is being normal from
20/Oct/1976 on, after the discontinuation of transmission of MSS
LANDSAT-1 data.
The improvements to be made at the Quick-Look Formatter are
tentatively scheduled for the middle of 1977. The manufacturer has
contacted us and no further delays are being expected after placing the
order.

2.3.2 - ELECTRONIC IMAGE PROCESSING LABORATORY
Processed LANDSAT-I MSS data (up to February 28, 1977) = 405
orbits.
. Processed LANDSAT-2 MSS data (up to February 28, 1977) = 19
orbits.
. No deliverable RBV data processed yet.
. Gen rated CCT scenes (from October 1976 to February 28, 1977) =
= 75.
During the last five months the Electronic Laboratory
produced a net number of 143 new orbits (approximately 3.100 scenes)
besides 90 orbits regenerated for the Photographic Laboratory master
archive. In the past, the Photographic Laboratory did not have second
generation negative film to produce products to users. The procedure was
to use the first generation that now needed to be regenerated. So, the
production rate for films (orbits) increased from 13,4 orbits/month
to 28,6 orbits/month.
NOTE: a - 281 orbits - Jan/75 to Sep 30/76 - 21 months
b - 143 orbits - Oct/76 to Feb 28/77 - 5 months.

number of 28,6 new orbits/month could not be higher
only due to the reduced quantity of acceptable quality 70 mm film
(SO	 219) rolls.
Concerning RBV data, we are presently testing our
operational software to generate film imagery, calibrated under computer
control.
On August/September of this year we expect the delivery
of the additional computer subsystem that will incrcase our processing
I
capabilities, specially with regard to the production support activities,
software development, production control, Photographic Laboratory supppovt
and data dissemination.
The computer subsystem will be a POP 11T/34 with the
following characteristics:
48K words memory
7.5 M Bytes disc memory
2 display terminals
1 hardcopy terminal
I printer (180 characters	 per	 second)
1 bus switch (to allow sharing the Mag Tape Units with the
existing system).

During the months of January and February considerable
changes had affected the Photographic Laboratory production. These changes
were related to the following activities:
establishment of the final parameters for the automated
production line with respect to the B/W 2nd and 3rd generation
film products and 3rd generation paper products;
development of primary tests for color composites which will help
the CCRS adviser (Mr. "Ernest Nagy), that is coning to Brazil, in
the establishment of the final parameters for the color production
line.
It must be mentioned that the former constraints in our
importation channels had forced us to accomodate our production to the
ma'?rial (paper and chemistry) available in Brazil. However this
procedure caused us several problems concerning the quality of our 3rd
generation products, this is, density range, contrast and appropriate
characteristic curve for our typical ground truth (for example, images
of Amazonas region). Thus, we had to adopt the imported paper,
significantly changing our processing parameters, and forcing the automated
system to be extensively used to generate test images. The majority of
production for those months was manual, resulting in a number of images,
about 1000 B/W images,besides 100 color images,for demonstration purposes.
Any gray, there is the fi rm objective to achieve about
,i 30.000 images oy the end of :his year which would require an average rate
of 3.000 images/mcath during the next months.
An evidence of the success concerning the revision of the
operational procedures established in the Photographic Laboratory Quality
Control is that none of the images, provided to external users during the
period from July to December 1976, was returned to the Center.

A policy adopted by INPE for the dissemination of the
LANDSAT data, mainly with the actual prices and reduced delivery times,
continues to contribute for the growth of the number of users engaged on
the researc'	 and exploitation of natural r.-sources. Table below

In the beginning of this year, after revising our user

year of 1976 did not request any kind of data or information. These names
will certainly be again incorporated at any time they show interest in
the products.

SECTION III
FINAL CONSIDERATIONS
The Image Production Center, during January and February
1977 has presented a slight decrease in its overall system throuput due
to the unavoidable effects from the deep changes in the Photographic
Laboratory in switching from a manual to an automated production. Naturally,
the system had its potentiality greatly increased and by the next months
the production level will compensate this situation.
The Cuiaba Tracking and Receiving Station is now performing
_
with an excellent degree of reliability as far as noiseless recording and
1 ￿
tape alignment are concerned. This has improved i-n a special way our CCT
data quality.
The Electronic Laboratory with the additional maintenance
personnel	 's having now opportunity to exercise 	 its production mode for
RBV data under an operational basis.
	 Research and Development personnel
are conducting tests with the purpose of improving the
	 geometric accuracy
of film products.
Concerning the modifications to provide the existing
L
system with the capability to input and procv s the LANDSAT-C IR
	 thermal
band,	 INPE has established a working group to study the feasibility of
implementing the required changes with their own research and development
staff. Any way, the alternative to contact external manufacturers is still
being considered.
