Utility networks are related to a land base by digitised overlay or off-set measurements. These relations may be of cartographic or survey accurate nature.
Should change to the land base occur, conventional ‘rubber sheeting’ methods are error-prone and labour intensive while conventional GIS techniques to address the problem are very expensive. Changes to the land base will be on-going, so a methodology is required to fix the problem now and in future in the most efficient way.
