IDAO Screen shots
The difficulty encountered by
non-botanists when identifying species using standard flora is centered around
three major constraints, namely:
- The ability to identify the
species without its flowers or before it flowers;
- The use of dichotomous key,
which cannot tolerate any error and imposes the choice as well as the order
of questions; and
- The use of technical terms not
understood by the non-specialists.
ADVANTAGES OF IDAO
As part of an open-source
software initiative, OSCAR web version was developed for Web standards
It was successfully tested with Mozilla Firefox 1.5 (& above) and Opera 9 (&
The web version is not yet Internet Explorer compatible due to technical
problems of IE.
In order to minimize and resolve these
constraints, the identification
system uses a graphical system which reconstitutes the plants using images.
This method has several advantages:
- It only uses drawings instead of technical
- It provides users the freedom to choose the
character that needs to
- Missing information or data are permitted,
thus allowing for the
- Certain level of observational errors are also
- At each step of the identification process, a
probability of resemblance is calculated for each species.
Thus species are sorted by decreasing order of similarity.
- At each step and moment, users could access
the photos, the description, and the botanical illustrations of the species.
- In case users encounter doubt in the choice of
characters (for description), they could ask the program for the most
- If the probability of a species identified is
less than 100 percent, the program indicates the characters that contain bad
- Descriptions of the species can be available
through Internet Website with any type of browser.
- The program being multilingual, it caters to a
larger section of people.
- All the technical terms used are highlighted
and at a click, an hypertext illustrated definition is accessible.
