Thesis (MA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: At a social, ecological and biological level it is important tha t we gain a better understanding
of species distribution and the constraints to species distribution. Various modelling tools and
approaches are available to provide this type of functionality. The GARP (Genetic Algorithm
for Rule set Production) Modelling System (GMS) was selected because of its strong predictive
modelling abilities and its ability to represent the results of model iterations in both a tabular
and cartographic manner. A shortcoming in this system was identified in tha t it requires strong
information technology skills in order to carry out the modelling process. This can be attributed
to the lack of a user-friendly interface to the system. In order to address this a loosely coupled
system was developed that provides an easy to use web-based front end to the GMS. This
Integrated Modelling System extends the core functionality of the GMS by providing a system
that provides detailed history for each analysis, allows fine tuning of the modelling process,
integrates directly with a biodiversity database containing specimen observations, and provides
a simple ‘wizard’ interface to the modelling process. / AFRIKAANSE OPSOMMING: Van ’n sosiale, ekologiese en biologiese standpunt is dit belangrik dat ons spesies verspreiding
en die beperkings daarvan verstaan. ’n Verskeidenheid sagteware pakkette en metodologiee
is beskikbaar om spesies verspreiding te modelleer. Die GARP (Genetic Algorithm for Rule
set Production) sagteware was gebruik vir sy sterk voorspellingsvermoe, en sy kapasiteit vir
kartografiese en tubulere tentoonstelling van model resultate. ’n Tekortkoming met hierdie
stelsel was gei'dentifiseer - dit is nie gebruikersvriendelik nie en gebruikers het sterk informasie
tegnologie vermoens nodig. Om hierdie tekortkominge aan te spreek was ’n sagteware program
ontwerp wat van GARP gebruik maak deur middel van ’n webblaaier.
Hierdie ge'integreerde stelsel bou op die basiese funksionaliteit van GARP om ’n werk omgewing
te skep wat ’n gedetailleerde geskiedenis van elke model stoor, fyn beheer oor die model toelaat,
direk met ’n bio diver siteits databasis koppel, en van ’n eenvoudige ’wizard’ stelsel gebruik maak
om gebruikers opsies te bepaal.
