Hydrographic Survey Management Guidelines

8 Data rendering and submission

Once the field survey is completed and the survey party has returned to the office, the steps and methods outlined in the regional Hydrographic Survey QMS procedures must be followed in order to complete the survey project. These could include the following:

  • file numbers should be obtained from Hydrographic Data Center (HDC) / Data management in order to properly identify and store the various information collected and produced in the field (digital files, observation notes, computation notes, descriptions, field sheets etc.),
  • all source data such as observations, computations, forms, etc. should be assembled, grouped, labelled, and submitted to the HDC. Make sure that everything is verified and approved,
  • the revisory report and Sailing Directions report should be completed including a list of the information which is to be replaced,
  • all sounding notes should be assembled, sorted and properly identified including date, name of launch or vessel, survey party, etc.,
  • all documents taken out of the HDC must be returned,
  • tidal information, water level records (digital or analogue), levelling notes, bench mark descriptions, photographs, comparison forms, vertical datum determination, location of water level staffs and gauges, etc.) must be assembled and properly labelled.

The various products and other information collected must be forwarded to the appropriate sections, groups or authorities, in order that the various databases, files, products, etc. may be updated. More specifically:

  • all products requested by external clients should be completed and sent in the most expedient fashion possible – a copy should be retained in HDC/regional database,
  • once verified, the data should be forwarded to the regional data manager,
  • data in the datasets used to generate field sheets, if required, should be coded according to the PSCG,
  • all raw data should be properly labelled and archived,
  • the revisory report including the list of charting actions should be forwarded to the regional data manager,
  • the Sailing Directions report and marina information should be forwarded to the regional data manager,
  • the horizontal control point data (descriptions and calculations) should be submitted to the federal, provincial or local authorities in charge of updating the horizontal control point databases. Copies must be sent to the regional data manager,
  • the Fixed Aid Tabulation forms, describing the fixed aid and listing the observed position should be sent to the appropriate regional Coast Guard office in order to update their database. Copies must be sent to the regional data manager,
  • all field notes pertaining to the establishment of bench marks and water level gauges should be submitted to the regional Tides and Water Level unit,
  • all physical sounding rolls and other bathymetric records must be forwarded to HDC and stored in a safe environment.
