Résumé(disponible en anglais seulement)
Geographic reference grids are used to organize many types of spatially referenced information, including information about oil and gas exploration, development activities and lease holdings. As grid systems differ among jurisdictions, digital reference grids have been computed for British Columbia (BC Land grid); Manitoba, Saskatchewan, Alberta and the Peace River area of British Columbia (Dominion Land Survey grid); and Yukon, Nunavut and the Northwest Territories as well as Canada's offshore regions in the Atlantic, Arctic and Pacific Oceans (Canada Land grid). In addition a National Topographic System (NTS grid) has been computed for all of Canada that extends well into the offshore (40 to 84 degrees North, and 48 to 144 degrees West). Theoretically derived grids are presented as a single collection on DVD in geographic coordinates (i.e. not projected) in a commonly used data format, ESRI SHAPE files.
The NTv2 National transformation is used to convert between NAD27 and NAD83 datums. The 2 Delphi NTv2 components extend the Geomatics Canada NTv2 Developer's kit, written in FORTRAN, to Delphi developers as components that can be dropped on a form to provide conversions using the Geomatics Canada NTV2 0.GSB or MAY76V20.GSB grid shift data. Note the latter is used in some Ontario basemaps. Executables use the NTV2.bpl or MAY76.bpl run-time library.
