This network is the primary level of the Manitoba Spatial Reference Network (MSRN) with the Manitoba Control Survey Network (MGSN) of the previous GPS, Inertial (ISS), Doppler, Triangulation Aerodist and Traverse Surveys forming the secondary level. The average spacing is on a 40-kilometre grid south of 52 degrees latitude on the West Side of Lake Winnipeg and 51 degrees on the East Side of the Lake. A linear spacing of approximately 40 kilometers is used north of the above mentioned latitudes along Provincial Highways and Public Roads. All horizontal coordinate values will be related to NAD83 (CSRS'98) publication and all Vertical values orthometric heights) will be related to the CGVD28 using GSD Geoid'95 geoid model. Purpose: To provide an accurate and reliable provincial control network of survey monuments that will allow full integration of survey work into the Canadian Spatial Reference System (CSRS).

Attribute_Accuracy: Attribute_Accuracy_Report: Attribute values are measured positions, either geodetic or utm. Station names are assigned based on year surveyed i.e. 95rxxx for 1995. Logical_Consistency_Report: All points are unique and have been checked for duplicates. Completeness_Report: Data has been checked for omissions. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy on co-ordinate values is plus or minus 2cm. The points were measured by GPS and the resulting network was adjusted using least squares. The accepted residuals are usually 1.0cm per point. The network is constrained to a known epoch and datum such as CSRS98. The absolute accuracy is reliant on the adjustment on which the data is constrained. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The vertical data was measured using 2 methods and the accuracy is dependant on method. Spirit elevations are measured by conventional methods using a spirit level and conforming to the specifications and recommendations for control surveys and survey markers (1978). The minimum accepted order is third (+- 24mm * sq. rt. dist.). Gps derived elevations are based on vertical differences measured by GPS using GSD'95 Geoid Model. During the free adjustment 1 or 2 points are fixed to known geodetic values and the values are checked to other known geodetic values. The residuals are usually as good as or better than the minimum accepted third order specifications as described above. A fixed adjustment that holds all known values fixed.

These points were measured by GPS equipment and methods and the resulting data was checked for completeness and accuracy. A free adjustment is run to determine the network accuracy and points that have residuals of greater than 2cm are either dropped or re-measured. The data is then fixed to a known datum and adjustment (CSRS98).

Overview_Description: Entity_and_Attribute_Overview: Point data represents control survey markers that have been measured by Gobal Positioning Systems equipment and referenced to the North American Datum 1983 (NAD83). The attribute data contains 4 distinct attribute fields being the 1. Epoch - The adjustment name representing a dataset based on a fixed point in time. 2.Datum_h - The horizontal geodetic reference datum. 3.Network - The specific sub-network within the dataset each containing their own specific accuracy statements. 4. Station_h - The unique identifier for control points. Entity_and_Attribute_Detail_Citation: Top
