A Framework for Update Process in GIS
Data update is a significant stage in the life of a geographical information system (GIS). In many cases, GIS are based on data provided by organizations such as the cadaster. The data transfer between a producer and a user is then often a bulk transfer. We study problems arising from the integration of this new data in the user GIS. To improve this data integration, we propose a two-step process: (1) Altered objects are detected in the transfer dataset. (2) Then, connections between altered reference data and data that replace it are established.
