Most companies or governmental agencies in the Earth Science industry advocate a web interface to facilitate user access to their valuable data. However those interfaces are all different and make it difficult for any user willing to discover, search, access and use this data in an easy and standardised manner. Those needs are particularly evident in the recent field of geothermal exploration in Australia where no such workflow is currently available. This paper presents the Western Australian Geothermal Centre of Excellence (WAGCoE) data catalogue, an application of recent geo-referenced web service technologies to address the challenges of locating, querying, and accessing data in standard formats for geothermal exploration. Practical uses of this catalogue for knowledge sharing and decision making within WAGCoE and the geothermal industry are also presented.
