| With more and more applications of multimedia data emerging in geospatial contexts, researchers have recognized that the combined use of multimedia data and geospatial data can offer good solutions to solve problems in both social and physical science domains. A new concept "cybercartography" has been proposed in the geography community to integrate digital cartographic products with multimedia data such as photographs, videos, still images, audios, texts, virtual reality and even multisensory data on the Internet. This study will present research methodology and key findings on profiling metadata for georeferenced multimedia data in a geospatial context.; The Cybercartography and New Economy project is developing two atlases based on the concept of "cybercartography". An OpenGIS compliant catalog will be developed to enable the access, sharing and reuse of large amounts of multimedia data, through metadata. Since multimedia data is a relatively new scientific data type in the geography community, there is no metadata standard that is readily available for describing it. This paper will introduce a new approach of developing a metadata profile by a combined use of different metadata standards for the purpose of making multimedia data more manageable, accessible, shareable and reusable in a geospatial context. Metadata information visualization of a geospatial web portal will also be discussed as an efficient means of facilitating efficient data access and retrieval. |
