PHOTOGRAMMETRIC ENGINEERING & REMOTE SENSING
BOOK
REVIEW
reader wanting. Part 1’s perspective seemed singular for such
a broad text. Although the preface billed the text possibly suit-
able as a textbook for undergraduate or graduate students this
reviewer feels that the preface was more correct in encourag-
ing this to be a supplement to a textbook or as a reference book
for researchers.
Part 3—Image Processing
includes Chapter 9 on ener-
gy-aware video compression; Chapter 10 on rotation and
scale-invariant template matchings and Chapter 11 on 3D-
TV. As I read this sitting at my desk thinking about the im-
age chain,

my heart dropped and my disappointment became
clear and proved my folly in cover/title judging. There was
nothing about image capture at all, nor was encoding or atmo-
sphere or even transmission to be read here. Although the au-
thors do from a perspective address a type of image processing,
I was left wondering about how Remote Sensing got forgotten
in the discussion. But, just like my British friends like to tell
me, “Melissa, the America Revolution only got one paragraph
in our 8th-grade history book, I don’t remember much about
it…” In the broadness of the topic “
Signals and Images
” the
perspectives that come out of Remote Sensing and Photogram-
metry were overlooked or did not register as of much impor-
tance to these authors. Probably, the book review editor at the
time, myself, misjudged the book’s audience and should have
paid closer attention to the Table of Contents.

There is much we in Remote Sensing can learn about signal
capture, signal encoding, signal processing, and signal trans-
mission, first and foremost is to remind ourselves regularly that
every image is a signal encoded for our viewing pleasure and
secondly there is a whole branch of knowledge devoted to under-
standing that better. Although, I learned much from this book
and do recommend it, probably the most important takeaway
today is to encourage our readership to not lose sight of their
image chain. Asking questions like 1) “How / When / Where /
Why was this image captured?” 2) “How / When / Where / Why
has this image been processed?” 3) “How does that effect my
intentioned uses of the image?”
We must stand firm in the collection and maintenance of
metadata. Remembering that time way back when, when
your professor gave you that checklist and you knew that your
“bits“ and “bytes,” and “brooms” had better be in order and
if you had band interleave, band sequential was not going to
load for your viewing pleasure, so pay attention. No matter
how far away we get from those checklists do not forget to re-
member your professor asking you, time and again, how was
this image captured and what has happened to it since then?
