Although conceived for the teaching of marine remote sensing BILKO is not inherently
limited either to teaching or to oceanography.  It is a versatile image
processing tool in its own right, with the potential for use in such fields as
geology, agriculture, pollution control and urban planning.  It does not have
all the features of specialist professional programmes but it allows a full
analysis of images of modest size and its analyses are carried out at useful
speed.

Interest in BILKO centres on the possibility that it may be used (i) to
improve the teaching in remote sensing of ocean and coastal waters, (ii) to foster cooperation and the
exchange of experience among teachers, and (iii) to bring the advanced skills of
image processing and analysis to large numbers of students who do not
otherwise have access to specialist facilities.

It is envisaged that the present project  will be advanced in five ways.  These
are: extended circulation of the present module; feedback on existing and future
lessons; writing of additional lessons; networking; and upgrading the available
software.  The rate of development in these different activities is not set: it
will depend on the interest shown and, inevitably, on the availability of funds.

{\bf 1.  Circulation}

Copies of this module are available on request.  They will be supplied at no
cost until supplies are depleted. 

Note that recipients of the module are free to make copies of both text and
discs for students and colleagues, but copies should not be sold.  Note also that disc 4  has a file from which it
is possible to print out a copy of this module.  This file is in \TeX\  format.

{\bf 2. Feedback}

The authors of the first module present their lessons for evaluation and
positive criticism.  Reports on student use of the module will be welcomed as
will be exemplifications of how lessons might be improved or usefully modified.
 For lesson modifications, the preferred medium is the floppy disc with
accompanying text copied as an additional file on the disc.

{\bf 3. Further lessons}

One function of this module is to act as an open invitation to those involved in teaching  marine
science to create new lessons, or lessons similar to those of this module but
with applications in different geographical areas.  It will be of particular
interest to extend the geographical coverage of the lessons to tropical waters.

No specific lesson format is prescribed, indeed the programme will benefit from
variety of exposition.  Intending authors should, however, observe some basic
rules.  In particular, they should:

\begingroup\parindent=20pt

\item{$\bullet$} provide introductory paragraphs which will allow potential users of a lesson
to assess whether it is likely to be of relevance to their work;

\item{$\bullet$} note any particular equipment requirements of the lesson;

\item{$\bullet$} use images which have been geometrically corrrected and radiometrically
calibrated wherever possible;

\item{$\bullet$} clearly identify the author of the work.

\endgroup

The {\bf aims}, {\bf objectives}, {\bf background} format of lessons in the present  module is one way of
covering the first two points.  Authors should note in this connection the
convention that {\bf aims} describe the aspirations of a teacher in setting a
lesson and {\bf objectives} list what a student should be able to do on
completion of the lesson.

Correction and calibration of images is certainly not mandatory but one aim of
this educational project is to demonstrate the quantitative use of remote
sensing so it seems prudent to avoid  the use of {\bf satellite pictures}.  National
remote sensing centres will often be able to provide corrected image data, but
intending authors who have access only to a personal computer and the BILKO
software may obtain help from the authors of this module.

{\bf 4.  Networking}

Lists of those interested in receiving lessons or modules, and of lessons
written in response to this initiative, will be maintained by the Unesco TREDMAR programme.
This programme  will also promote  an informal network for the exchange and dissemination
of new lessons, through  the exchange of floppy discs.

If the project generates a sufficient level of interest, the intention is that
collections of lessons will be circulated in the form of modules similar in
style to the present one.
Articles in such modules will be treated as conventional academic publications,
with the unusual feature that the illustrations - the digital images that is -
will be addressable by readers on a pixel-by-pixel basis.

Even using high density floppy discs, it is unlikely that it will be possible to
circulate large numbers of modules for the number of discs involved will be
formidable.  A long term solution to this problem may be to publish  a number of modules in
the form of a CD-ROM.  Intending authors are invited to give their views on this
possibility.

{\bf 5. Upgrading}



A final point to note is that BILKO runs in the 8-bit, 512 x 512 format of the
EGA display system at a time when 32-bit machines with powerful and
sophisticated display systems are becoming more common.  A policy of system
enhancement to satisfy the requirements of those having enhanced capability, and
of downwards compatibility for those who do not, is essential.

One development, now in hand, is the creation of a version of BILKO for VGA
systems.  Other developments may be expected and, as a cooperative network for teaching marine remote sensing develops, this may provide a suitable forum for the
exchange of information with which to specify the software requirements of more
advanced display systems.
