Abstract
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.
Claims29
1) Apparatus for defining a parcel network in a control coordinate system, the parcel network being formed from a number of interconnected parcels, and each parcel being formed from a number of interconnected boundary lines, the apparatus including:
- a) An input for receiving survey data defining the number of parcels, the survey data specifying the distance and direction between end points of the interconnected boundary lines for each parcel;
- b) A store for storing the survey data;
- c) A display;
- and,
- d) A processor adapted to:
- i) Join the parcels together to form the parcel network, the parcel network being defined in terms of network coordinates, the network coordinates defining the relative positions of network points in a network coordinate system, each network point corresponding to the position of a parcel end point within the network;
- and,
- ii) Map the coordinates of the network points into the control coordinate system.
13) Apparatus for defining a parcel network in a control coordinate system, the parcel network being formed from a number of interconnected parcels, and each parcel being formed from a number of interconnected boundary lines, the apparatus being substantially as hereinbefore described with reference to the accompanying drawings.
14) A method of defining a parcel network in a control coordinate system, the parcel network being formed from a number of interconnected parcels, and each parcel being formed from a number of interconnected boundary lines, the method including:
- a) Receiving survey data defining the number of parcels, the survey data specifying the distance and direction between end points of the interconnected boundary lines for each parcel;
- b) Joining the parcels together to form the parcel network, the parcel network being defined in terms of network coordinates, the network coordinates defining the relative positions of network points in a network coordinate system, each network point corresponding to the position of a parcel end point within the network;
- and,
- c) Mapping the coordinates of the network points into the control coordinate system.
25) A method of defining a parcel network in a control coordinate system, the parcel network being formed from a number of interconnected parcels, and each parcel being formed from a number of interconnected boundary lines, the apparatus being substantially as hereinbefore described with reference to the accompanying drawings.
26) A computer program product comprising computer executable code for causing a processor to perform the method of any of claims 14 to 26.
27) A computer program product defining a parcel network in a control coordinate system, the parcel network being formed from a number of interconnected parcels, and each parcel being formed from a number of interconnected boundary lines, the apparatus being substantially as hereinbefore described with reference to the accompanying drawings.
