come to know that one PC to two trainees is quite
preferable after all. The two can help each other and
result in better understanding than using it. alone.
4.1 Curriculum
Due to limitation of budget, schedules of the participants,
etc., the time period of the training within the seminar
was set to three days. The schedule was as follows.
Day 1:
(1) Introduction to the hands-on-training
(2) Remote Sensing
(a) Introduction to remote sensing
(b) Image enhancement
(c) Geometric correction
Day 2:
(d) Multispectral classification
(e) Change detection
(3) GIS
(a) Introduction to GIS
(b) Land resource allocation« part 1»
Day 3:
(c) Land resource allocation< part 2>
(d) Digital terrain model
(4) Discussion
4.2 Software Packages
There are very good un-expensive training software such
as IDRISI or ILWIS. They charge only minimum cost to
maintain and improve their software. This is quite
practical way to maintain a training software, and is
accepted by many users. However, there are still strong
needs for good public domain software for training.
[n order to allow beginners to use remote sensing and GIS
software freely at their offices, the authors have decided
to prepare public domain software for remote sensing and
3IS. Actually, within the frame work of the seminar,
some of the authors and others have developed several
software for training under the support of NASDA,
UNCRD, etc. The main software packages are
WinASEAN for remote sensing and GIWIN for GIS. The
both software packages run on IBM PC compatible
machines with MS-Windows. The software are
carefully developed for the beginner's use. But at the
same time, it can also be used for professional use. The
user can easily step up from training to their daily work
by using the same system.
The software are released through the frame work of the
seminar as a public domain software for training. The
ISPRS Commission VI working group 2 “Computer
Assisted Teaching” is providing the software to users
upon request on voluntary basis. The essence of the two
26
packages are summarizes as follows.
4.2.1 WinASEAN
(Outline
WinASEAN is an image processing software for remote
sensing developed by one of the authors Nguyen Duong
and others of the National Centre for Natural Science and
technologyof Vietnum under the technical cooperation
with the Remote Sensing Technology Center of Japan
(RESTEC) and the financial support from NASDA.
(2) Functions
The main functions of the WinASEAN are as follows.
- Preprocessing: Data conversion, histogram calculation,
image enhancement, filtering etc.
- Image display
- Classification: Training area selection,
training data statistic calculation,
maximum likelihood classification, etc.
- Geometric correction
- Change analysis
- Bird eye view generation
(3)Hardware Requirement
- CPU: 386, 486 or above
- Math coprocessor
- Base memory: 640KB
- Extended memory: 3MB or more
- Floppy disk drive : 5.25 or 3.5 inches
- Hard disk memory : 80MB or more
- Super VGA color monitor
- 24 bits graphic accelerator for Windows environment
- CD-ROM drive
- Mouse
- Printer
- Microsoft Windows 3.1 or latter version pre-installed
4.2.2 GIWIN
(1)Outline
GIWIN is a GIS software package developed by one of the
authors Fuhu Ren to facilitate the GIS overlay functions
in land use suitability assessment and feasible resource
allocation. By giving certain constraint, criterion scores
and weights to each land related factor, automated
allocation of land resource for competitive multiple
objectives can be performed.
(2)Functions
- Data Management: file I/O, map display, image, etc.
- GIS Transforms:map category extraction, map overlay,
image algebra and spatial statistics.
- LRA Model: map coding, relevant factor weighting,
multiple criteria assessment and land
resource allocation.
- Graphic Editor: map legend generator, graphic tools,
drawing options.
