There was no license available for Microstation, so we did not
install Pro600, but changed the feature extraction exercise for
the available “Feature”-module. As we were not familiar with
this module, we had to learn about it and then adapt the course
material for it. We spent all Saturday and Sunday to help with
the installation of the computer systems, install the
Photogrammetric software and the data needed for the course
and fit the stereo shutters to the monitors.
Due to an error in the license file of the software the
preparations could not e completed by Sunday evening. On
Monday morning help from the software vendor came very
prompt and precise, which allowed us to start the course on
Monday after the lunch break.
Language turned out to be a problem. As half of the member
states supporting RECTAS are francophone, there were some
course participant unfit to follow the course in English language.
It was impossible to translate all the course material to French,
especially as we had to spend a lot of time to adapt the English
material to the local configuration and the different release of
the software. To overcome the language problem the course was
given in the following way:
. Course material was provided only in English;
= Introductory lectures and discussions were bilingual (ie.
everything was said in 2 languages, every contribution of
course participants was first translated to the other
language and then a reaction was given in both
languages);
. Exercise groups were formed such, that there were 2
English groups, one bilingual group and 2 French groups.
Each one of the French groups had one very well bilingual
group member in order to support the non-English
speaking group members.
We managed to stay ahead of the program with the adaptation of
the material, although the assistance of both staff members was
needed throughout all exercises. Many lunch breaks, evening
hours and half the second weekend had to be sacrificed for this
goal.
On the last day a course evaluation by the participants was held
(by Rectas staff in order not to influence the participants with
our presence), then a closing ceremony was held in which the
director and the deputy director of RECTAS together with the
two staff members of ITC handed a bilingual "Certificate of
Participation" to each participant. The directorate of RECTAS
also handed a “Certificate of Appreciation” to each of the staff
members of ITC. The day was concluded with a dinner of all
participants and all involved staff.
Remark
Each part was started with an introduction and/or a small
background lecture. The material (only in English!) was given in
print to the participants and also projected on a screen while
explanations were given in both languages. Hands on exercises
were carried out in groups of three or four course participants,
with assistance by two staff members constantly available. Each
part was concluded with a (bilingual) discussion. Projection of
lecture material was used when appropriate for clarifications in
those discussions. Also during the practical the CCD-projector
was used for support.
During part of one session the local representative of the
software vendor (Mr. Greuter) was available for a discussion
about the software used (SOCET SET from LH-Systems).

6. EVALUATION & RECOMMENDATION (MADE BY
RECTAS & BY ITC STAFF)
6.1. A successful evaluation by *rectas" Nigeria
After an introduction of a refresher course in digital
photogrammetry at RECTAS “Ile-Ife, Nigeria”, a positive
feedback “through an evaluation” [reported to ITC from
RECTAS] has been received “including participant from 8
ECA-member states (mix of Francophone and English speaking
in West Africa: Nigeria, Ghana, Cameroon, Mali, Senegal,
Niger, Burkina Faso and Benin). From RECTAS staff and from
participants evaluation stated that such a refresher course is very
much demanding at their organization. The participants were
extremely motivated and many spent more time on the systems
than allotted. Some even spent part of the weekend to repeat
parts they were not sure enough of. -
6.2 Individual assessment made by RECTAS together with
course participants
Practically all the participants remarked that the course was just
right and that it has helped to open their eyes to new techniques
in photogrammetry through the training they got from this
