This layer provides the extents of influence that the work to integrate survey information has on the surrounding Cadastre.

All cadastral surveys must be integrated into the Cadastre. As part of this process the new information 'upgrades' the existing information. This is controlled by a mathematical adjustment process using a Least Squares methodology.

The adjustment/Integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extend of the change largely depends upon the size of the new survey, the difference in accuracy between new and old data and the number of linkages to other Surveys.

In general, where the underlying surveys are older or in a rural location the greater the extent of the adjustment.
