Abstract

Spatial metadata is a vital tool for spatial data management, retrieval and distribution. It is also a critical component for any spatial data sharing platform which provides users with information about the purpose, quality, actuality and accuracy of spatial datasets. With the amount of exchanging spatial data through the web environment, the demand for spatial metadata automatic creation and update to describe such resources is increasing. However, spatial metadata automatic update is still in its infancy and automatic approaches are being explored by researchers. With this in mind, this paper aims at exploring a new synchronisation approach to automate spatial metadata update process, by which dataset properties are read from the dataset file and written into its metadata file automatically. The paper firstly discusses the important role of metadata in Spatial Data Infrastructure (SDI) as an enabling platform and proposes architecture to manage spatial metadata. It then compares different methods of spatial metadata generation and presents a spatial metadata automation framework. Based on this framework, the paper finally introduces a synchronisation approach to achieve the spatial metadata automatic update.
