In the case of # overlapping coverage, the program selects the data file with # the smallest grid cell in the region of the conversion. If # the grid cell sizes are the same, the program selects the # file which appears first in this file. Check the Help # file for more options. # # Order the list of files as appropriate for your application. # You can add additional files as they become available. While # the name, letter case, and location of the file name is not # importantant, the extension must be ".gsb" if the file is in # the Canadian National Transformation, Version 2 format. Each # line may be a full path name. The ".\" sequence used here is # a relative folder/directory reference, relative to the folder # (directory) in which this file resides. # # The file referenced by the following line of text is not part # of the distribution. The fact that it doesn't exist will # cause an error message when a conversion with this datum # is attempted. # # CSRS requires a different grid shift file for every province # in Canada. Each province in Canada produces and maintain # their own file. They must be obtained from the relevant # provincial ministry responsible for geodesy. For web links # on where to obtain these, see: # http://www.geod.nrcan.gc.ca/prov_contact/index_e.php # #.\Canada\CSRS\PQA8398.gsb #.\Canada\CSRS\SK83-98.gsb # Saskatchewan #.\Canada\CSRS\NAD83-98.gsb # Quebec #.\Canada\CSRS\AB_CSRS.DAC # Alberta # # You can add a "Fallback=???" specification below, but since the # shift is so very small 20 - 40 cm), it is unlikely that this will # help any.
