OS VECTORMAPTM DISTRICT: AUTOMATED GENERALISATION, TEXT PLACEMENT AND CONFLATION IN SUPPORT OF MAKING PUBIC DATA PUBLIC

摘要

Automatic generalisation has proved to offer a cost-effective solution for creating OS VectorMap District. The project has also proved the value of investing in enhancements to the National Geographic Database, without which the creation of OS VectorMap District would have been impossible. The project has highlighted the importance of conducting long-term research, to prepare the organisation for creating new cartographic products on demand. Ordnance Survey Research continues to investigate technologies to support the creation of new products and replacement of legacy production systems with modern automated vector systems. The development of a single geographic names database has been significantly progressed as a result of the OS VectorMap District project. This database will continue to be enhanced, and as it improves, so too will the quality of the cartographic text placement in automatically derived products. Long-term this will replace the disparate names datasets maintained by Ordnance Survey, reducing data maintenance costs and the new product creation costs.
