Thesis (MSc)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: The recognition and description of relief features from their contour patterns is recognized as
the main challenge in topographic map education. Conducting field exercises can solve this
problem, but can be very time consuming. Modern technology, however, provides an
alternative teaching technique by creating depictions of terrain. Important issues raised by this
new approach include questions such as what these depictions should look like and how it
should be presented to the user.
Research presented here aims to address these issues by constructing design guidelines for
terrain depiction. These design guidelines were derived from previous research and case
studies. The guidelines focussed on research about how people perceive different
representations of terrain and how these representations should optimally be presented. The
design guidelines were constructed from research done in diverse fields such as cognitive
psychology, cartography and engineering. Results of this research revealed that in order to
develop an effective terrain visualization tool, it is crucial to incorporate different fields of
expertise.
The design guidelines were implemented with ArcView GIS and its 3D Analyst extension,
which has the ability to display spatial data in three dimensions. The final product is called
Terrain Visualization Tool 1.1 (TVT) and was created by customizing an ArcView GIS project
(TV BUILDER) and constructing a Website (TV VIEWER). TV BUILDER creates the
visualization data in the form of 20 web pages per topographic area and links them to TV
VIEWER that serves as a platform to view the data. The design guidelines were implemented
successfully and show the advantages of using Geographical Information Systems (GIS) in
related research. / AFRIKAANSE OPSOMMING: Die identifisering en beskrywing van landskapelemente vanaf hul kontoere is geidentifiseer as
die primere uitdaging in topografiese kaartonderrig. Hierdie probleem kan oorkom word deur
kaartleesoefeninge in die veld te onderneem, maar dit neem baie tyd in beslag. Modeme
tegnologie maak ‘n alternatiewe onderrigmedium moontlik deur die skep van verskillende
landskapsuitbeeldings. Hierdie alternatief laat die vraag ontstaan hoe die uitbeeldings moet
lyk en hoe dit aan die gebruiker aangebied moet word.
Die doel van hierdie navorsing spreek hierdie vrae aan deur ontwerpriglyne vir landskap
uitbeelding daar te stel. Die ontwerpriglyne is saamgestel deur bestudering van vorige
navorsing en studies wat op hierdie gebied gedoen is. Die riglyne fokus veral op navorsing
wat mense se reaksie op verskillende landskapuitbeeldings ondersoek. Die ontwerpriglyne is
egter saamgestel deur navorsing wat gedoen is in velde soos kognitiewe sielkunde, kartografie
en ingenieurswese. Hierdie navorsing het bewys dat inkorporasie van verskillende studievelde
in die ontwikkeling van terrein visualiseringstoepassings essensieel is.
Die riglyne is geimplementeer deur gebruik te maak van ArcView GIS en die 3D Analyst
uitbreiding wat die vermoe het om data in drie dimensies uit te beeld. Die finale produk
genaamd Terrain Visualization Tool 1.1 (TVT) bestaan uit twee komponente, naamlik ‘n
aangepaste ArcView GIS projek (TV BUILDER) en ‘n webwerf (TV VIEWER). TV
BUILDER skep die landskapsuitbeeldings van een topografiese area in die vorm van 20 web
bladsye en verbind dit met TV VIEWER, wat as ‘n platform dien om die landskap
uitbeeldings te beskou. Die ontwerpriglyne is suksesvol geimplementeer, wat die voordele
van Geografiese Inligtingstelsels (GIS) in hierdie en soortgelyke toekomstige navorsing
demonstreer.
