Abstract
A survey monument comprises a conventional water hydrant with survey indicia or markings attached thereto. The survey indicia can be carried for example on a plate mounted on a flange bolt or attached to the operating nut of the hydrant. These survey monuments can be expanded upon and/or maintained in co-ordination with the expansion and maintenance of a municipality'"'"'s water supply system. The hydrants can also be utilized in connection with any geographical information system to provide known reference points. The hydrants can also be utlized in connection with GPS devices to assist in localizing, initializing and calibrating the same.

27. Method of gathering geographical information for a geographical information system with the use of a positioning device, using a hydrant as a reference location for said system, said method including the steps of:
-
(a) placing said positioning device proximate a hydrant monument;
(b) entering the known position of hydrant monument into the positioning device.
-
- 28. A method of using a geographical information system in conducting a survey, said geographical information system comprising a plurality of hydrant monuments having accorded thereto in said geographical information system known locations in at least 2 dimensional space, said method comprising the steps of (a) identifying a hydrant monument (b) accessing said geographical information system to ascertain the location information of said hydrant and (c) conducting a survey operation from said hydrant.
- 31. A method of surveying comprising using a hydrant monument having a known location in at least 2 dimensional space as a survey monument in conducting a survey.
- 34. A method of surveying comprising mounting a survey instrument on a hydrant said hydrant having a known location in at least 2 dimensional space.
-
36. A computer program adapted for generating a visual representation of a section of terrain in the real world, said representation including indicators for a series of computer generated fire hydrants corresponding to fire hydrants in said section of terrain, said fire hydrants in said section of terrain having known co-ordinates for inputting into said computer program as location control points for said computer generated representation, whereby when said known co-ordinates corresponding to said series of fire hydrants in said section of terrain are inputted to said computer program as location control points, said computer program will generate a representation having all features shown in the representation in their true relative positions.

37. A computer program for generating a map or model having a plurality of location control points corresponding to fire hydrants in the real world, each of said fire hydrants having co-ordinates in the real world stored in said computer program.
-
38. A method of creating a map comprising using a plurality of hydrants the location of which is known in the real world as a plurality of control points, and rubber-sheeting a data set with reference to said control points to properly position a plurality of features on said map in a proper position relative to each other.
- 39. A method of surveying including the step of sighting with a survey instrument onto a hydrant monument the location of which is known in at least 2 dimensional space.
- 45. A method of surveying including the step of sighting from a hydrant monument the location of which is known in at least 2 dimensional space, onto a survey target.
