Abstract

A radio frequency identification survey monument system that quickly and easily locates a land survey monument and receives important land survey information relating to land where monument is located which was entered by a land surveyor. Information can be transferred to a computer. Radio frequency identification (RFID) technology is combined with land surveying resulting in a new system for improving current system of locating a monument and retrieving data regarding land survey. This invention improves ability to locate monument with accuracy from current technology which uses a magnetometer to locate monument within three (3) to four (4) feet of magnetometer, to a distance of at least fifteen (15) feet or more with the present invention.

Claims

1. A radio frequency identification survey monument system comprising:

a radio frequency identification transponder tag operative to store information for marking and identifying a location on a region of land and transmit the information to a reader; and

a reader operative to excite the transponder tag and receive and process the signal transmitted by the radio frequency identification transponder tag.

2. The radio frequency identification survey monument system of claim 1 further comprising a survey monument cap that includes the radio frequency identification transponder tag.

3. The radio frequency identification survey monument system of claim 1 wherein the transponder tag is operative to allow the reader to provide location information.

4. The radio frequency identification survey monument system of claim 1 wherein the transponder tag is operative to allow the reader to provide information regarding at least one of a personal identity of a land surveyor and crew members who set monument, date and weather at time monument was set, type of equipment used to set monument, a depth of a monument, a set of land coordinates, Cadd files and field notes or property descriptions, deed and title information regarding region of land and surrounding land, station and offset information relating to construction plans, and any problems incurred when surveying property or right of way.

5. The radio frequency identification survey monument system of claim 1 wherein the reader can read the signal from the transponder tag at a range of at least 15 feet from the reader.

6. The radio frequency identification survey monument system of claim 1 wherein the reader can read the signal from the transponder tag at a range of at least 30 feet from the reader.

7. The radio frequency identification survey monument system of claim 1 wherein the reader can read the signal from the transponder tag for a duration of at least one year.

8. The radio frequency identification survey monument system of claim 1 wherein the reader is operative to transfer information received to a computer.

9. The radio frequency identification survey monument system of claim 2 wherein the survey monument cap is made of a material selected from the group consisting of plastic.

10. The radio frequency identification survey monument system of claim 2 further comprising a survey monument operative to fit within the survey monument cap.

11. The radio frequency identification survey monument system of claim 8 wherein the survey monument is made of a material selected from the group consisting of concrete, metal and plastic.

12. The radio frequency identification survey monument system of claim 8 wherein the information received by the computer is processed by computer software.

13. The radio frequency identification survey monument system of claim 12 wherein the computer software is operative to convert information from the transponder tag to at least one program language.

14. The radio frequency identification survey monument system of claim 1 wherein the transponder tag is operative to continue to transmit the signal to the reader when the transponder tag is buried under ground.

15. The radio frequency identification survey monument system of claim 10 further comprising an external antenna that when above ground and the transponder tag is buried under ground can transmit the signal to the reader.

16. The radio frequency identification survey monument system of claim 11 wherein the antenna is a wire.

17. A method of obtaining information about a location of land including the steps of:

transmitting to a reader with a transponder tag;

receiving a radio frequency signal from a transponder tag located at the location;

processing the radio frequency signal to obtain the information about the location; and

converting the information with computer software into a program language.

18. The method of claim 17 wherein the step of receiving a radio frequency signal includes a step of locating land survey monument system with a reader.

19. The method of claim 18 wherein the step of receiving a radio frequency signal includes the steps of receiving information with a reader and processing the information with the reader.

20. The method of claim 19 including the step of transferring information from the reader to a computer.
