GPSMeasurements12. Measurements can be derived by GPS. The survey shall be performedusing proven GPS Techniques with sufficient independent checkmeasurements to eliminate the possibility of gross error in anymeasurement. The control network configuration and survey practicesshall meet the currently adopted guidelines and specifications for GPSSurveys.13. All measured lengths shall be reduced to horizontal at general ground leveland expressed in metres and decimals thereof on the plan of survey.Legal SurveysProceduresCurvesMonuments14. Legal Surveys on Northern Road Right of Ways shall be performed inaccordance with the provisions of PART II of this manual except as notedhereafter.15. Simple curves shall be used except where, in the opinion of the Surveyor,compound curves are required to properly retrace construction curves.Constructed highway spirals shall be surveyed as outlined in PART II, Subsection3. (2).16. (1) Legal survey monuments shall be established at the commencement andend of the survey, beginning and end of curves, deflection points, andadjacent to survey control. The maximum distance betweenmonuments shall not exceed 1000 metres.(2) Where it is impossible or impracticable to establish a monument on anew road right of way limit, the monument shall be established on theright of way limit on either side of the obstruction or at 90 degrees fromthe survey line opposite the point.MonumentExceptionsTopographicalFeaturesGeodeticTolerances17. Monuments cut down to 15 centimetres in length and set 8 centimetres intorock or brass caps cemented into bedrock may be substituted at positionsthat fall in rock.18. Sufficient measurements shall be taken to define the position of all majortopographical features adjacent to the road right of way, i.e., river banks,lake shore, centre thread of named streams. Additional information of thisnature may be added by scaling from aerial photos when available.19. A mathematical closure shall be obtained between the legal surveymeasurements and the Geodetic coordinates obtained at the beginning andend of the survey. The calculations shall include appropriate correctionssuch as distance reduction to ellipsoid or UTM scale factor. The maximumallowable limit of non-closure shall not exceed one part in ten thousand.20
PART IVPublic Improvement SurveysPublic improvements are lands acquired for any public service pursuant to TheHighways and Transportation Act.1. Public Improvements shall be marked on the ground by establishingmonuments at every change in direction, at the intersection of a sectionline, previously surveyed line, and the intersection with the monumentedlimits of a previously registered survey.2. Where a limit of a public improvement intersects a curve, the beginningand end of curve shall be defined as stated in Part I, Sub-section 7. (2) toestablish the curve intersection.3. The monuments marking the limits of a Public Improvement shall not benumbered.4. Where it is impossible or impracticable to establish a monument on thePublic Improvement limit due to a slough, marsh or other obstruction, amonument shall be established referencing the obstructed corner on eitherlimit and measurements shown to the referenced monument.MonumentsCurveIntersectionMonumentNumberingObstructionssloughDist.21
