Land surveying apparatus and method of use thereof
First Claim
1. A land surveying apparatus for real-time acquisition of earth position data and land distance data, the apparatus comprising:
- a distance measuring instrument coupled to a land vehicle, the distance measuring instrument configured to receive input regarding a distance the land vehicle travels on the land and to output land distance data regarding the distance;
a GPS receiver coupled to the land vehicle, the GPS receiver configured to receive GPS signals and to output earth position data regarding a position of the GPS receiver on the surface of the earth as a function of the received GPS signals;
a controller which generates a plurality of sample intervals, which for each sample interval acquires the earth position data output by the GPS receiver and the land distance data output by the distance measuring instrument, and which relates the land distance data and the earth position data as a function of the corresponding sample interval; and
a memory coupled to the controller for storing for each sample interval the corresponding earth position data and land distance data.

Abstract
A land surveying apparatus for real-time acquisition of earth position data and land distance data includes a distance measuring instrument, a GPS receiver, a controller and a memory coupled to a land vehicle. The distance measuring instrument receives input regarding a distance the land vehicle travels on the land and outputs land distance data regarding the distance. The GPS receiver receives GPS signals and outputs earth position data regarding a position of the GPS receiver on the surface of the earth as a function of the received GPS signals. The controller generates a plurality of sample intervals, and acquires for each sample interval the earth position data output by the GPS receiver and the land distance data output by the distance measuring instrument. The controller relates the land distance data and the earth position data as a function of the corresponding sample interval and stores in a memory for each sample interval the corresponding earth position data and land distance data.

11. A land surveying apparatus for real-time acquisition of earth position data and land distance data, the apparatus comprising:
-
a distance measuring instrument coupled to a land vehicle, with the distance measuring instrument determining a distance the land vehicle travels on the land and outputing land distance data corresponding to the distance;
a GPS receiver coupled to the land vehicle, the GPS receiver configured to receive GPS signals and to output as a function of the GPS signals received for each of a plurality of positions of the land vehicle on the land waypoint data, wherein each waypoint data includes at least two of a longitude, a latitude and an altitude of the land vehicle on the land;
a controller which generates a plurality of sample intervals, which acquires for each sample interval the waypoint data output by the GPS receiver and the land distance data output by the distance measuring instrument, and which relates for each sample interval the acquired waypoint data and land distance data; and
a memory coupled to the controller for storing for each sample interval the acquired waypoint data and land distance data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of land surveying comprising the steps of:
-
(a) providing a system including a distance measuring instrument (DMI) and a global positioning system (GPS) receiver connected to a controller;
(b) traveling along a path with the system;
(c) causing the controller to generate a plurality of sample intervals;
(d) acquiring for each sample interval earth position data output by the GPS receiver and land distance data output by the DMI;
(e) relating for each sample interval the acquired earth position data and acquired land distance data;
(f) storing in a memory coupled to the controller for each sample interval the acquired earth position data and the acquired land distance data; and
(g) displaying the stored earth position data and/or the stored land distance data output on a display coupled to the controller, wherein the controller causes the display to display a map that includes, for each of one or more sample intervals, indicia corresponding to at least one of the earth position data and land distance data for the sample interval, where each indicia displayed on the map is located at a map coordinate position corresponding to an earth coordinate position determined from the earth position data for the sample interval.
