Programs and their control cards in current use by the Office for
Remote Sensing of Earth Resources (ORSER) at Penn State are described.
These include programs of the following types: 1) a program to obtain
information about the contents of a tape from the tape internal label,
2) a subsetting program, 3) programs for creating brightness and
uniformity maps, 4) a program to obtain basic statistics for user-
defined small blocks of data, 5) supervised classifiers which classify
data from a set of user-specified spectral signatures according to the
angle or distance of separation, 6) unsupervised classifiers which
develop their own set of spectral signatures using a clustering algo-
rithm, 7) a program using the method of canonical analysis to derive
an orthogonal transformation which maximizes category separability on
as few axes as possible, 8) a classification and mapping program based
on the ratio of two selected channels of data, 9) a program which merges
data from two different passes of ERTS over the same area, 10) a program
which compares, elementby element, two digital classification maps of
the same ground area, 11) a series of classifiers employing the linear
discriminant function, and 12) a series of classifiers employing the
quadratic discriminant function. The digital aircraft multispectral
scanner data tape format used by ORSER is also described. Instructions
and examples of computer processing of both ERTS and aircraft multispectral
scanner data, using cards or the Remote Job Entry terminal, are included;
