Abstract
This study quantitatively and qualitatively compares new annual mean precipitation and temperature surfaces for China produced using neurointerpolation (Bryan and Adams, submitted) with Gestalt climate maps (Editorial Committee of the Physical Geography of China, 1995) at a variety of scales. The new mean precipitation and temperature maps display good broad scale correspondence with the Gestalt maps. However, correspondence decreases at increasingly finer scales. The new climate maps capture substantial fine-scale spatial variation seemingly driven by topographic influences and continentality that is not present on the Gestalt maps. The precipitation map however, lacks important subregional scale variation in several areas. It is concluded that whilst improved climate maps may quite readily be produced by neurointerpolation, it is still imperative to validate the new maps with Gestalt maps which consider a more complex set of indicators than climate station and topographic data alone.

Abstract
Spatial and temporal variation in water quality was investigated for the Upper Talbot Brook catchment, Western Australia, during the period of June to August, 1998. Data from water samples, land use questionnaires, GIS analysis and remote sensing were used to provide an inclusive view of water quality variability and investigate possible causes of the variations. This investigation makes particular use of spatial data and GIS functionality to facilitate the selection of sampling sites, the mapping of remnant vegetation and land use, and an analysis of variability in water quality through time.

Abstract
For more than 100 years the Geological Survey of Western Australia (GSWA) has acquired, enhanced, archived and disseminated regional geological, geophysical, geochemical, mineral and petroleum data as a fundamental component of its work program. Geoscientific Database of Western Australia (GeoBASE.WA) signifies a change in GSWA's approach to the management and distribution of these geoscientific data. GeoBASE.WA moves away from the standard map-centric structure, to a data-centric approach, thereby providing improved access to a single source of data for a variety of needs including quality hardcopy maps and remote access to seamless geoscientific datasets. By making the geoscientific information readily available within GeoBASE.WA, these data can be incorporated into decision-making processes thereby promoting mineral and petroleum exploration in Western Australia.

Abstract
Having spanned a quarter of a century, the Broken Hill Mapping Project represents a powerful example of the discipline of cartography adapting to the impact of changing technology. The Broken Hill mapping series saw the transition from manual cartographic methods such as scribing, masking, rub-down lettering, to the use of computers with basic graphics software, and currently, to the more sophisticated use of GIS technology. This paper presents an overview of the evolving methodology devised and developed by the staff of the Cartographic Section, Department of Mineral Resources (New South Wales), to produce the complex maps of today.

Abstract
MapLibrarian is a digital and online solution for interactive spatial querying and management of map and spatial data collections. MapLibrarian opens access to map collections to a global audience and offers searching services twenty-four hours a day. The MapLibrarian software solution removes the burden of paper-based index maintenance and improves the accuracy of collection inventory data. Built using industry standards and an open-architecture design, MapLibrarian is a unique application of spatial information technology in the traditional world of map collection management.
