587908 Disclosed is a system for creating the boundaries of a number of subdivision lots (12). The system comprises a computer and stored instructions for defining the boundaries of a selected parent lot (10), within which the subdivision lots (12) are to be provided. The instructions include stored instructions for creating a software model of the parent block (10) including the establishment of the external boundaries of the parent block (10) on the existing Cadastral framework. The instructions also include stored instructions for connection of the external boundaries of the parent lot (10) to the geodetic framework and stored instructions for converting the boundaries of the parent lot (10) to a local coordinate system. There are also provided stored instructions for converting the local coordinates to establish coordinates consistent with the geodetic network and stored instructions for creating a number of subdivision lots (12). The subdivision lots (12) are all within the parent lot (10) and are created by electronically generating data which creates the boundaries of each of the subdivision lots (12) such that the subdivision lots (12) are created so that the boundaries of each subdivision lot (12) are spaced apart from and within the boundaries of the parent lot (10). The location of each subdivision lot (12) is defined by the coordinates on the geodetic network to survey accuracy.
