Digital Photogrammetry refresher course. All of the participants
said the programme is worth mentioning to their colleagues and
would advise them to participate in similar training in the future.
Some even suggested that decision makers should be sensitised
so as to draw their attention to this new technology in
photogrammetry.
According to the assessment of some of the participants, some
shortcomings were apparent, these were:
(a) Short time of the course duration as many believed that
such programme should have lasted for a little longer - say
4 weeks at least, for them to be able to master it very well.
(b) Cost (in 2001) of the software - $70,000.00! an amount
which they think may be rather high for the African
environment. The suggestion offered is that software less
costly may encourage many buyers.
(c) Ratio of participants to computer system is reduced to say,
| system to 2 trainees.
(d) Training materials for practical should be from the
immediate environment to make participants familiar with
the terrain thereby making the training more real than
virtual.
(e) Software written in French also is solicited for the
francophone.
6.3 Assessment made by ITC staff members
For the evaluation of the course by the participants English and
a French version of a questionnaire was given to the participants
to be filled in. All participants took part in the evaluation and
there were 7 English and 9 French forms handed in. In total the
result was very positive. In the annex the English form is
included as well as a summary of the answers
Giving the course was very demanding, (a lot of free time had to
be sacrificed to do it properly), but also very rewarding. 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. It is
highly recommendable to give such a course to different groups
(in different parts of the world or perhaps at the ITC, where
occasionally up to 50 participants could be accommodated), as
there is definitely a need for it. Bilingual groups should however
be avoided. The need and the feasibility of translating the
material and giving the course in other languages than English
(e.g. French or Spanish) should be investigated.
7. CONCLUSION
As mentioned about a refresher course ran at RECTAS Nigeria,
the course was a very useful and very successful one; to be able
to support mapping techniques and/or operations (at various
organizations and/or institution), this type of support should be
organized. Many participants urged ITC to contribute to the
awareness of this technology at the political level (only then
sufficient funds will be available to make the switch in near
future). Basically this course could be used for this purpose with
some modifications, such that the duration is reduced to a single
week and hands on practices are reduced considerably and/or
substituted by demonstrations. Background lectures and
discussions will have to occupy more time for this scenario.
