Abstract

A system for evaluating data points against cadastral regulations to include a plurality of software modules programmed into a computer system with software and hardware configured to store and update a cadastral rule database containing a plurality of rules for determining the validity of the cadastral data (10). The cadastral database obtained from a data source reference data that is indicative of a plurality of established reference data points wherein the received input data corresponds to a plurality of measured data points with steps to co-process the input data and the referenced data according to the plurality of cadastral rules to determine an indication for the plurality of data points (20).

Claims

1. A system for evaluating data points against at least one cadastral regulation comprising a plurality of software modules programmed into a computer, the computer having a CPU, a memory, and I/O hardware, the plurality of modules being configured to:

(a) store and update a cadastral rule database containing a plurality of rules for determining validity of cadastral data;

(b) obtain from a data source reference data indicative of a plurality of established reference data points;

(c) receive input data corresponding to a plurality of measured data points; and

(d) co-process the input data and the reference data according to the plurality of rules to determine an indication of validity for the plurality of data points.

2. The system of claim 1, wherein the plurality of modules further includes a method definition module adapted to define at least one regulation method to operate upon a data point type, the at least one regulation method including:

at least one of the plurality of rules for the co-processing;

a specification of a textual regulation descriptor.

3. The system of claim 2, wherein the method definition module is further adapted define at least one regulation method for at least three data points including:

a new horizontal point (NHP);

a new vertical control point (NVC) and a new boundary point (NBP).

4. The system of claim 2, wherein the coordinate operating functions include:

a calculation method to adjust data point coordinate values to allow closure of the data points; and

a transformation method to transform an internal coordinate network associated with the input data to another coordinate network associated with at least one reference point.

5. The system of claim 4, wherein the plurality of modules further includes a rule editor module activated by the method definition module, the rule editor module configured to input, edit, and recall from the cadastral rule database at least one regulation rule of the plurality of rules.

6. The system of claim 5, wherein the rule editor module is further configured to edit rule parameters of the at least one regulation rule and to update and include the at least one regulation rule, along with at least one of the plurality of rules for the co-processing, in the at least one regulation method.

7. The system of claim 6, wherein the rule parameters include generic rule parameters and specific rule parameters.

8. The system of claim 7 wherein the generic rule parameters include:

a specification to apply or not to apply the coordinate operating functions during co-processing and an indication of a rule category, including at least;

point, measurement, and structure.

9. The system of claim 2, wherein the plurality of modules further includes a co-processing and reporting module adapted to co-process the input data and the reference data according to the at least one regulation method, and the co-processing and reporting module is further adapted to output a report indicating a validity status for each point of the plurality of data points.

10. The system of claim 9, wherein the validity status includes:

pass, fail, and warning.

11. A method for evaluating data points against at least one cadastral regulation comprising the steps of:

(a) storing and updating a cadastral rule database containing a plurality of rules for determining validity of cadastral data;

(b) obtaining from a data source reference data indicative of a plurality of established reference data points;

(c) receiving input data corresponding to a plurality of measured data points; and

(d) co-processing the input data and the reference data according to the plurality of rules to determine an indication of validity for the plurality of data points.

12. A system for providing validation information during recording of data points for a cadastral survey, the system comprising:

(a) a field survey measuring device for measuring data points relative to a measurement network; and

(b) a validation subsystem in data communication with the field surveyor measuring device, the validation subsystem being configured to;

(i) receive data point measurement information from the measuring device,

(ii) process the information according to a plurality of rules to determine an indication of validity of the data point, and

(iii) output the indication of validity to the operator of the measuring device.

13. The system of claim 12, wherein the validation subsystem includes a plurality of software modules programmed into a computer, the plurality of modules being configured to:

(a) store and update a cadastral rule database containing a plurality of rules for determining validity of cadastral data; and

(b) obtain from a data source reference data indicative of a plurality of established reference data points, the cadastral rule database and the plurality of established reference data points being used in processing the information.

14. The system of claim 12, wherein the field survey measuring device and the validation subsystem are incorporated into a common housing.

15. The system of claim 12, wherein the field survey measuring device and the validation subsystem are in data communication via a wide area communication network.

16. The system of claim 12, wherein the field survey measuring device and the validation subsystem are in data communication via wireless communication.
