Abstract
The Australian Surveying and Land Information Group (AUSLIG) committed itself to the quality validation of GEODATA products. This paper describes
the approach taken by AUSLIG to GEODATA TOPO-250K quality validation and the statistical principles on which the approach is based.

Abstract
This paper reports progress on a multidisciplinary research project at Murdoch University, involving the disciplines of information systems, cartography
and law. The research project is examining how information systems may be best utilised to support the negotiation and arbitration of native title (land)
claims by indigenous Australians. It also addresses important methodological issues relating to the analysis, design and evaluation of information systems
which accommodate users with different cultural backgrounds. It discusses the requirements of relevant spatial information systems and some of the
design considerations for suitable maps and other visualisations. An initial analysis of the GIS needs of the National Native Title Tribunal is provided.
Map Based Information Products: A Multimedia Definition and Some Issues and Opportunities.

Abstract
The Australian Government recently (October 18, 1994) pledged Aus$84 million dollars to a multimedia initiative, embodied in the Creative Nation Cultural Policy Statement. This initiative will aid in the greater acceptance of multimedia in the professional and educational sectors and will assist
multimedia in penetrating the 'general' population markets on a wider scale. Markets for multimedia are being created and cartographers may find it
beneficial to try to exploit the new opportunities these markets present, no matter how limited they are at present. This paper aims to succinctly define a
multimedia 'map based information product' (MBIP) and associated concepts and to discuss some of the major issues of concern to the cartographer in
terms of multimedia and cartography.

Abstract
This paper describes the development of a (semi)automated process for detection of a road network in a forest area near Perth, Western Australia using
SPOT satellite images. Initially, the imagery was processed with specially designed local spatial operators, where the primal sketch was extracted. The
data were then linked and vectorised, and C programs used to extract low-level image features from the spatial domain. The method also utilised
morphological operators to give a geometric description of the linear features. Subsequently, a prototype expert system was implemented to improve the
results. Knowledge was encoded in the form of rules, incorporated into a backward chaining expert system shell, VP-Expert. Based on the attributes of
the low level image features, the knowledge base defines the road network by eliminating extraneous elements from the image. The system utilises only
data derived from the image, without ancillary information from other sources, keeping the process 'autonomous'. Results showed good correlation
between the road network extracted from the SPOT data and the structure of the ground features. Application of the system to a second test area
confirmed these results.

Abstract
Computer Assisted Learning (CAL) has received significant attention in the educational arena for some time, with acceptance in schools, tertiary
institutions and continuing professional development. Due to the relatively low demand in the mapping sciences area, resources have not previously been
directed towards the development of CAL packages.
The receipt of two research grants in 1989/90 and 1993/94 provided the opportunity to formulate two projects with the aim of developing CAL materials
on remote sensing. This paper examines two facets: (1) the motivation behind the development of CAL software; and (2) some of the design
considerations and challenges associated with the development of CAL modules. These aspects are examined from the perspective of the authors who
have experience in using and creating CAL software for remote sensing instruction.
An Evaluative Approach for Colour Printing Technology in Cartography

Abstract
The automation of map production methods has increased the importance and relevance of electronic output. This paper outlines an experiment that was
carried out to identify the most suitable technologies for short run map production and general graphics. For cartographic firms intending to buy an
electronic output device, the methodology serves as a guide to the design of a test map and the objective and subjective testing of map elements. Ten
different printers incorporating electrostatic, bubble jet, ink jet, thermal wax, dye sublimation, colour laser and film recorder technologies are tested in
this experiment. The evaluation of the suitability of a printing device for map reproduction was based on objective density and line weight measurements,
and subjective ranking.
Terrain Modelling as an Aid to Historic Visualisation

Abstract
This investigation was born out of an interest in military history and the desire to develop cartographic visualisation through digital terrain models
(DTMs). The project set about creating a digital terrain model of an artillery site and the associated tunnel network in the vicinity. The site, named
Buckland Hill, is located near Fremantle, Western Australia. The project was completed using the Intergraph MSM (MGE) Terrain Modeller package, in
conjunction with Microstation 4. Windows Paintshop was used to enhance the final images.
This paper provides a brief outline of the Buckland Hill history and details of the application of MGE Terrain Modeller. It also describes the stages
involved in completing the project and provides brief conclusions.
