Otjec*_ive/Scope: The ohiective of this investigation is to evaluate Landsat-4
Thematic Mapper (TM) data performance and utility characteristics from an
energy research and technology perspective. The program focuses on evaluating
appiicational implications of using such data, in combination with other
digital data, for current and future energy research and technology activi-
ties. Prime interest is in using TM data for siting, developing and operating
federal energy facilities. Seconuary interests involve the use of such data
for resource exploration, environmental monitoring and basic scientific
? n7 *_` 3t1 ve5 such as in su pport Of the Continental     ^C i eiit i f i C Dr i i i i ng r r ograim.
Approach: The basic approach is to utilize digital remote sensing/image
processing and data integration techniques developed at the U.S. Department of
S.ner3Y's Pacific Northwest Laboratory for processing, analyzing and evaluating
Landsat-4 Thematic Mapper data. Data analysis and evaluation emphasis is on
Landsa t--4 TM data use in studies of the Columbia Plateau region in eastern
Washington in general and the Hanford site in specific. However, Landsat TM
ca to for other representative energy research and production sites are being
analyzed and evaluated as well. Table 1 identifies the main image data
.;i,ality characterization areas of investigation and the prime application
areas of interest.
data Status: To date, no Landsat-4 TM data have been received for our prime !
s*..udy sit: in the Columbia Plateau region of eastern Washington state.
Excellent data were acquired for the Har 4crd site during the TORS test on
w,^ust 12, 1983, but CCTs have not as yet been received. Table 2 summarizes
Landsat-4 TM data available to date and ancillary data sets being utilized.
Accomoiishments/Preliminary Results:
_. Oeveioprrent of TM Image Analysis Programs. In anticipation of the 7-band
Landsat-4 TM data, two special programs were developed for simultaneously
using a vector scope and a color raster display. The first (Figure 1) is
both a multiband or multisource program that provides for rapid,
; +'era-tive enhancement and generation of multiband color composites
containing the optimum combination of TM bands to highlight features of

prime interest. The second program (Figure 2) emphasizes quantitative
single-band analysis for determining the digital counts (radiometric
values) associated with a specific pixel (so called pixel-level) or as an
integrated (multipixel -level) value for larger features or areas of
interest.
2. TMS Data Anal ysis. Prior to the receipt J Landsat-4 TM data, NASA ERL
pro— v- ided PNL with Thematic Mapper Simulator (TMS) data for a nuclear
power plant (Virginia Electric Power Company-North Ar.na Plant) to test
the previously developed image processing algorithms. Princip,l compo-
nent analyses of this data set clearly indicated that thermal plumes in
surface waters used for reactor cooling would be discernible on Landsat-4
TM data.
3. TRl Data Analysis. Because of TM data availability constraints to date,
data quality and utility analysis efforts have been limited to the
analysis and evaluation of TM day and night imagery acquired for DOE's
Savannah River Laboratory in Aiken, S.C. on August 28, 1982 and
December 24, 1982, respectively. Moreover, beca usE
 
of the uniqueness of
the thermal band data, major emphasis was given to analyzing this band.
The results of analysis efforts to date are described and graphically
demonstrated in the two publications cited below. Basically, qualitative
effort;. indicate that the geometric and radiometric characteristics of
the TM (CCT-PT) data are adequate to support most of our requirements for
generating specialized enhancements, multiband composites and data
integration (multisource) products. Quantitative findings, associated
with TM thermal band analyses, although very preliminary indicate several
potentialities for providing quantitative thermal data of the type
required for basic research, modeling and energy facility monitoring
functions. However, much more information and user experience are
required relating to limitations imposed by calibration, data processing,
atmospheric and sub-pixel or mixed-pixel effects.
