Data for seismic surveys prior to 1999 were obtained from National Energy Board (NEB) as points data (end points and bends) in Excel file format with basic information only. The NEB dataset was not comprehensive. Seismic lines coordinates' data for some of the earliest surveys recorded during 1960s and 1970s were recorded in NAD27 and contained location errors. In addition some data were not converted to NAD83 datum currently in use therefore resulting in even larger error. Starting at 1999 seismic lines location data are provided to the Government of Yukon by exploration companies as part of their statutory reporting requirements.
