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 measuring and evaluating the accuracy of geodetic measurements comprising:

a field survey measuring device; and

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;

store and update a regulation rules database containing a plurality of regulation rules for determining validity of geodetic measurements;

select at least one data point type to be evaluated;

select at least one regulation rule from said plurality of regulation rules;

select at least one regulation calculation method from said regulation rules database;

receive input measured data points from said field survey measuring device corresponding to said at least one data point type;

obtain, from a data source, reference data indicative of a plurality of established reference data points;

co-process the input measured data points and the reference data points according to said at least one data point-type, said at least one regulation rule and said at least one regulation calculation method to determine an indication of validity for the accuracy of the measured data points in real time, said at least one regulation rule comprising an evaluation indicator indicating when said at least one regulation calculation method is to be applied to said input measured data points, said co-process comprising;

evaluating said input measured data points based on said at least one regulation calculation method; and

evaluating said input measured data points and said reference data points based on said at least one regulation rule; and

generate a report indicating the validity of the measured data points in real time,

said plurality of modules further including a method definition module adapted to define at least one regulation method to operate upon a selected data point type, the at least one regulation method including;

at least one rule for the co-processing;

a specification of a textual regulation descriptor; and

coordinate operating functions including;

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.

2. The system of claim 1, wherein the method definition module is further adapted to define at least one regulation method for at least three data points including:

a new horizontal control point (NHC);

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

3. The system of claim 1, wherein the plurality of modules further includes a rule editor module activated by the method definition module, the rule editor module being configured to input, edit, and recall from the regulation rules database at least one regulation rule from the plurality of regulation rules.

4. The system of claim 3, 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 the at least one of the plurality of rules for the co-processing, in the at least one regulation method.

5. The system of claim 4, wherein the rule parameters include generic rule parameters and specific rule parameters.

6. The system of claim 5 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.

7. The system of claim 1, wherein the report indicates a validity status for each point coordinate of the measured data points.

8. The system of claim 7, wherein the validity status includes:

pass, fail, and warning.

9. The system of claim 1 wherein said field survey measuring device and said computer are housed in a common housing.

10. The system of claim 9 wherein said common housing is a portable common housing.

11. The system of claim 1 wherein said evaluation indicator indicates that said evaluating said input measured data points based on said at least one regulation calculation method is to be performed prior to said evaluating said input measured data points and said reference data points based on said at least one regulation rule.

12. The system of claim 1 wherein said evaluation indicator indicates that said evaluating said input measured data points based on said at least one regulation calculation method is to be performed after said evaluating said input measured data points and said reference data points based on said at least one regulation rule.

13. The system of claim 1 wherein said plurality of established reference points include at least one of a permanent global positioning system (GPS) station, a licensed horizontal control point and a licensed horizontal and vertical control point.

14. A method for measuring and evaluating the accuracy of measurements of geodetic data points, the method comprising:

storing and updating a regulation rules database containing a plurality of regulation rules for determining validity of measured geodetic data points;

selecting at least one data point type to be evaluated;

selecting at least one regulation rule from said plurality of regulation rules;

selecting at least one regulation calculation method from said regulation rules database;

receiving measured input data from a field survey measuring device corresponding to said at least one data point type;

obtaining, from a data source, reference data indicative of a plurality of established reference data points;

co-processing the measured input data and the reference data according to said at least one data point type, said at least one regulation rule and said at least one regulation calculation method to determine an indication of validity for the accuracy of the measured input data in real time, said at least one regulation rule comprising an evaluation indicator indicating when said at least one regulation calculation method is to be applied to said input measured data points, said co-processing comprising;

evaluating said input measured data points based on said at least one regulation calculation method; and

evaluating said input measured data points and said reference data points based on said at least one regulation rule;

defining at least one regulation method to operate upon a selected data point type, the at least one regulation method including;

at least one rule for the co-processing;

a specification of a textual regulation descriptor; and

coordinate operating functions including;

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 and

generating a report indicating the validity of the measured input data-in real time.
