ItemIncremental update and upgrade of Spatial Data( 2000)This paper examines issues relating to the update and upgrade of the digital cadastral map. Of central interest is the transfer of incremental update and upgrade data from the custodian to the user and possible solutions for the associativity problem. The paper clearly differentiates between spatial update and upgrade and categorises three different methods for the transfer of incremental upgrade information. The impact on both the users and the custodian of the cadastral map are discussed in view of providing the most efficient and timely incremental upgrade information. A strategy that provides the maximum information to the users about the shift in the digital cadastral map and additional serves as input information for any adjustment procedures the user utilise to minimise the associativity problem. While this paper draws on the authors’ experience of maintenance of cadastral maps in the Australian states of Victoria and New South Wales and the German state of Berlin, the efficient delivery of updates and especially upgrades of the spatial cadastral data to users is of interest to users of spatial data.

ItemFacilitating disaster management using SDI( 2004)The role of spatial data and related technologies in disaster management has been well-known worldwide. One of the challenges concerned with such a role is access to and usage of reliable, accurate and up-to-date spatial data for disaster management. This is a very important aspect to disaster response as timely, up-to-date and accurate spatial data describing the current situation is paramount to successfully responding to an emergency. This includes information about available resources, access to roads and damaged areas, required resources, and required disaster response operations that should be available and accessible for use in a short period of time. Sharing this information between involved parties in disaster management is a challenge to facilitate coordinated disaster response operations. This paper aims to address the role of Spatial Data Infrastructures (SDI) as a framework for facilitating disaster management. It is argued that the design and implementation of an SDI model as a framework and consideration of SDI development factors and issues can assist disaster management agencies to improve the quality of their decision-making and increase efficiency and effectiveness in all levels of disaster management activities. The paper is based on an ongoing research project on the development of an SDI conceptual model for disaster management in Iran. This includes the development of a prototype web-based system which can facilitate sharing, access and use of data in disaster management and particularly disaster response.
