ABSTRACT:
Success in imagery understanding and interpretation is greatly dependant on our knowledge of the earth surface geography and
geomorphology as well as all kinds of man-made features and activities, which has changed the nature either positively or negatively
in considerable areas on Earth. It is quite important to know about the components of the earth surface and physico-chemical factors,
which has controlled the development of the surface and configurations of image elements including soil/rocks, vegetation and urban
activity. To achieve a reasonable understanding of an image or map, one should start with knowing or revising relevant scientific
phenomena’s of chemistry, physics, geology/ geomorphology / geography, basic mathematics and statistics, maps and how to use
computers. This introduction to basic scientific concepts will be followed by an introduction to map reading & projections, remote
sensing, image processing, principles of imagery interpretation and an overview of imagery applications with emphasis on the
specific field of application of each user.
Practically oriented education of imagery users is very essential for better utilization of images and enable profitable investments in
remote sensing technology applications.
1. INTRODUCTION
1.1. Motivation and aim
From the fact that I am working as a remote sensing, image
processing & interpretation and maps training advisor in the
United Arab Emirates (UAE), Universal Ground Station
(UGS), for the past five years, and because the majority of the
technical employees are undergraduates; with high school or
diploma certification, it was necessary to implement a practical
& reasonable basic training program. This program is designed
only for new employees or imagery users without any relevant
background on remote sensing & maps. The aim is mainly to
enhance the understanding of scientific phenomena’s related to
remote sensing and maps with emphasis on practical issues to
help building a reasonable imagination and understanding
capability on how various ideas and concepts are interrelated
and integrated, to end up with a person who can correctly read a
map and interpret an image.
One encouraging and success factor is that the training cell of
the UGS is equipped with latest workstations, image processing
& GIS software products, data projection facility and
availability of different kinds of images parallel with qualified
trainers. This trial program intended to simply address the
subject first to imagery users who cares about visual
interpretation of hardcopy prints or just investigating images on
computer monitors, and secondly to those aiming to work as
professional image analysts and image-map production
specialists. The availability of images and software products in
the UGS enabled us to correctly address the subject through
image illustrations.
1.2. UGS overview
UAE was among the first countries to utilize high-resolution
images from all available commercial sources, including
IKONOS, SPOT, Quick Bird, Spin 2 as well as aerial
27
photographs collected by reconnaissance aircrafts and
unmanned aerial vehicles, for UAE territories and the
surrounding countries.
In 1999 H. H. Sheikh Mohammad Bin Zayed Al Nahyan, Chief
of Staff of UAE Armed Forces, patronage the establishment of
a national ground receiving station, and the UGS was
operational in late 2000, with help of Space Imaging, the owner
of IKONOS imaging satellite, a worldwide leading company in
high resolution satellite imaging business. Currently the UGS
directly receive imagery data from three satellite groups;
IKONOS, IRS and KOMPSAT.
During 1999 and up to October 2000, a total of 20 officers and
soldiers were trained by Space Imaging in USA, ITC in
Netherlands and in the Space Reconnaissance in Abu Dhabi, on
basics of remote sensing image processing, map reading and
image map production. Later on, trainees in small patches got
specific training on the application products required for
running a specific operational cell in the UGS; Satellite Tasking
& Controller, IRS Satellite data processing, Radio Frequency
Terminal operations, Requirement Manager, Image Analysis &
Production and Data Base Management.
In year 2001 few experts from Space Imaging came over to
UGS for on the job training and some employees were sent
abroad for specific training at operational level to keep them up
to date with latest system upgrades. In 2002 the UGS was fully
operated by nationals with only limited support by Space
Imaging help-disk and trainers who look after the basic training
and solving some system related problems.
2. METHODOLOGY & REQUIREMENTS
The training process in general consists of four principal
elements; trainees, trainers, materials& procedures and training
requirements. In addition, there will be an objective to achieve
a certain level of command in the real life operational level.
The trainee’s education level, experience and language are the
