Photogrammetric Engineering & Remote Sensing
is the official journal
of the American Society for Photogrammetry and Remote Sensing. It is
devoted to the exchange of ideas and information about the applications of
photogrammetry, remote sensing, and geographic information systems. The
technical activities of the Society are conducted through the following Technical
Divisions: Geographic Information Systems, Photogrammetric Applications,
Lidar, Primary Data Acquisition, Professional Practice, and Remote Sensing
Applications. Additional information on the functioning of the Technical
Divisions and the Society can be found in the Yearbook issue of
PE&RS
.

SUBSCRIPTION
.
For the 2014 subscription year, ASPRS is offering two op-
tions to our
PE&RS
subscribers -- an e-Subscription and the print edition.
E-subscribers can plus-up their subscriptions with printed copies for a small
additional charge. Print subscriptions are on a calendar-year basis that runs
from January through December. Electronic subscriptions run for twelve
months on an anniversary basis. We recommend that customers who choose
both e-Subscription and print (e-Subscription + Print) renew on a calen-
dar-year basis. The new electronic subscription includes access to ten years’
of digital back issues of
PE&RS
for online subscribers through the same
portal at no additional charge.
Please see the Frequently Asked Questions
about our journal subscriptions.
The rate of the e-Subscription (digital) Site License Only for USA and
Foreign: $899.00; e-Subscription (digital) Site License Only for Canada*:
$944.00;
Special Offers:
e-Subscription (digital) Plus Print for the USA:
$1,160.00; e-Subscription (digital) Plus Print Canada*: $1,224.00; e-Sub-
scription (digital) Plus Print Outside of the USA: $1,175.00; Printed-Sub-
scription Only for USA: $959.00; Printed-Subscription Only for Canada*:
$1,013.00; Printed-Subscription Only for Other Foreign: $974.00. *Note:

MEMBERSHIP
.
Membership is open to any person actively engaged in the
practice of photogrammetry, photointerpretation, remote sensing and geo-
graphic information systems; or who by means of education or profession
is interested in the application or development of these arts and sciences.
Membership is for one year, with renewal based on the anniversary date
of the month joined. Membership Dues include a 12-month subscription to
PE&RS
. Subscription is part of membership benefits and cannot be deducted
from annual dues. Beginning with the January 2014 issue of
PE&RS
, all
members outside of the USA will receive access to the full digital edition of
the journal rather than the printed copy. Dues for ASPRS Members outside
of the U.S. will now be the same as for members residing in the U.S. Annual
dues for Regular members (Active Member) is $150; for Student members it
is $50 for USA and Canada; $60 for Other Foreign (E-Journal – No hard copy
for all Students); for Associate Members it is $100 (member must be under
the age of 35, see description on application in the back of this Journal). A
tax of 5% for Canada’s Goods and Service Tax (GST #135123065) is applied
to all members residing in Canada

LETTER FROM ALAN MIKUNI PE
CP, ASPRS PAST PRESIDENT AND
CO-CHAIR UAS MAPPING 2015 RENO
continued on page 272
Dear Reader,
If you mention the term “Unmanned Aircraft
Systems” or “UAS” in casual conversation
with family, friends, or colleagues, you might
get the reaction of either a puzzled look or
a “what’s that?” (or both). In an immediate
attempt to clarify, you might say “you know,
drones
.” Then, you will probably observe
some level of recognition, likely based on perceptions gleaned
from news reports from foreign military theaters-of-operation,
and less-than-positive.
Of course, for those of us in the geospatial professions, UAS are
rapidly becoming familiar features of how research, applications,
and business are conducted in the imaging and geospatial
technology world. Another term, “disruptive technology,” aptly
describes what effect UAS are having on ASPRS disciplines. The
traditional means by which data are acquired, how the data are
processed, and the array of applications for aerial data have been
altered dramatically. Interest in the fundamentals of ASPRS
disciplines seems to be on the rise, and, as one ASPRS member
recently exclaimed, photogrammetry is alive and well, thank
goodness! Aerial mapping will never be the same.
It gives me great pleasure to introduce two papers devoted to
the topic of UAS in this issue of
PE&RS
. The Highlight Article,
“Testing a Small UAS for Mapping Artisanal Diamond Mining in
Africa”, by Katherine C. Malpeli and Peter G. Chirico, presents
a fascinating look at a particularly unique application for UAS.
Aspects of an adage related to UAS, that they are useful for
work that is “dull, dirty, or dangerous”, are demonstrated by the
authors of this paper. The work of aerial image acquisition of so-
call “blood diamond” mines and mining operations is dangerous
for the human scientists in strife-torn West and Central Africa.
Such activities are similarly dangerous for the quad-copter UAS
as native birds see the aircraft as a territorial threat, much like
the human residents of the region view human intruders. In his
monograph on UAS, “Overview and Current Status of Remote
Sensing Applications Based on Unmanned Aerial Vehicles
(UAVs)”, Gonzalo Pajares provides you an extensive treatise on
available remotely piloted aircraft, in particular, UAS platforms,
associated airborne sensors, their capabilities, and a glimpse at
the variety of applications for them. The author describes the
variety of fixed-winged and rotary-winged UAS, e.g., multi-rotor
“copters”. He also delves into the variety of sensors like RGB,
infrared, multispectral and hyperspectral cameras, LiDAR, and
radar/synthetic-aperture radar. He also describes a variety of
applications for these intriguing systems. The author concludes
by providing hundreds of references to enable the reader to
investigate further. Please enjoy and learn from the perspectives
