Incremental update and upgrade of Spatial Data

Scheu, Martin ; Effenberg, Wolfgang ; Williamson, Ian P. ( 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.
