PARCEL NETWORKS

摘要

The present invention provides apparatus for defining a parcel network in a control coordinate system. The parcel network is formed from a number of interconnected parcels with each parcel being formed from a number of interconnected boundary lines. The parcels are defined by survey data which specifies the distance and direction between end points of the interconnected boundary lines for each parcel. In use the apparatus operates to join the parcels together to form the parcel network, with the parcel network being defined in terms of network coordinates. The apparatus then maps the coordinates of the network points into the control coordinate system.
