Specialized Courses 
These courses are specialized either in one technique 
of remote sensing (photography, photo interpretation, 
digital image processing, etc) or in one special applica- 
tion of remote sensing (agricultural statistics, water 
resources managements, rangeland inventories, census 
cartography, human settlements, etc.). 
Duration : One month to five months. 
Entry Qualification : The minimum entry qualification 
for the course depends on the course being 
offered, and may be at the technician or 
engineer's level. 
Research and Study Courses 
High level scientists working in any field of remote 
sensing applications can find at CRTO technical and 
material aids appropriate to their research or study course. 
Duration : Depends on the background and progress of the 
student. 
Refresher Courses 
Objective : To develop exchange of information between 
CRTO and its former trainees. For partici- 
pants, the aim is to update their knowledge 
of remote sensing techniques, methodologies 
and available products of remote sensing. 
For CRTO, the aim is to continually re- 
evaluate the needs of users. 
Duration : Eight weeks. 
Outreach Seminars 
CRTO has initiated an oureach programme in the sub- 
region to inform both member and non member-states of the 
role and importance of remote sensing as a management 
tool and to advertise the services offered by the Centre. 
Duration : One week. 
Workshops 
CRTO's experts offer special practically oriented
