MANITOBA CONTROL DATA ARCHIVE – MARCH 2019 -------------------------------------------------------------------------------- Last revised 2016 The files in this directory refer to coordinates for the Manitoba control networks developed and maintained by GeoManitoba, Sustainable Development. All 3D coordinate values are NAD83(CSRS) Epoch 2010.0 (ITRF2008) with CGVD2013 heights. All 1D spirit levelled elevations are referenced to Canadian Geodetic Vertical Datum of 1928 (CGVD28) and Canadian Geodetic Vertical Datum 2013 (CGVD2013). DIRECTORY CONTENTS ------------------ README.TXT * This file. 3rd-order spirit levelling descriptions 2017-09-30.xlsx * Excel spreadsheet of textual monument descriptions for 3rd-order spirit levelling done by Surveys and Mapping Branch, Natural Resources prior to 1992. MCSM DISCLAIMER.txt MSRN2014 station listing 2018-07-13.xlsx * Excel spreadsheet of textual monument descriptions for the Manitoba Spatial Reference Network (MSRN) control monuments. OFFICIAL 3rd-order Spirit Levelling CGVD28 & CGVD2013 Elevations 2017-08-30.xlsx * Excel spreadsheet of 3rd-order spirit levelling done by Surveys and Mapping Branch, Natural Resources prior to 1992. The CGVD2013 heights were determined by a readjustment of the provincial CGVD28 spirit levelling networks constraining Canadian Geodetic Survey database values for the national 1st-order benchmark network. Official CGVD2013 heights are determined by applying the CGG2013 geoid model to NAD83(CSRS) Epoch 2010.0 ellipsoid heights through GNSS occupation. OFFICIAL MSRN2014 CBN 6.0 (Epoch 2010.0) Coordinates 2018-07-13.xlsx * Excel spreadsheet of the official NAD83(CSRS) Epoch 2010.0 coordinates derived from 2006 GPS observations on the MSRN. OFFICIAL SuperNet2014 CBN 6.0 (Epoch 2010.0) Coordinates 2018-07-13.xlsx * Excel spreadsheet of the official NAD83(CSRS) Epoch 2010.0 coordinates for various survey monuments occupied during GPS survey projects conducted between 1989 and 2014. These projects form a subset network within the MSRN, known as the SuperNet. SuperNet2014 station listing 2018-07-13.xlsx * Excel spreadsheet of textual monument descriptions for the Manitoba SuperNet control monuments.
