Some results and implications of performance tests on large nationwide spatial databases

Over the years attempts have been made to develop computer systems which amalgamate spatial data held in individual GIS systems enabling public enquiry facilities. For organisational, technical and data reasons, few such systems have been built and none are operational. Recent improvements in networking technology, spatial systems, and changes in computer architecture, have largely removed the constraints to such integrated systems. Near complete datasets in many organisations, coupled with a more sophisticated GIS and public user community, are leading to a user-led demand for more and easier access to comprehensive digital spatial data. The paper reports on the performance of an object-entity based spatial information system specifically designed for fast search and retrieval from large nationwide spatial databases. A brief description of the data model is provided, the results of single and multiple client tests given and some conclusions drawn.
