Streamlining the Process

• NOAA Hydrographers are required to verify and
  revise the depiction of shoreline portrayed on
  nautical charts
• H-Cell implemented by processing branches to
  expedite the application of new survey data to
  the ENC
• Retaining the positional integrity of the data
  collected in the field and producing the end
  product early in the process to obtain as much
  S-57 attribution while viewing the features in
  the field

3
Initial Goals of the Project

• Reduce ping-to-chart time
• Deliver a field product to the Office of Coast
  Survey which most easily enables the revision of
  ENC feature object information
• Display both acquired and reference data in an
  editable form in Notebook, with full S-57
  attribution
• Minimize data conversions

Pre-Acquisition

• Mapinfo
• Numerous source files of various formats reviewed
  compiled for field verification
• GeoTiff image (TIF/TFW) produced from source data
  
• GPS PathFinder
• (for use in Trimble TerraSync software)
• Configuration parameters setup in a config file
• Data Dictionary produced
• Trimble TerraSync
• GeoTiff image imported into software for display

6
Acquisition

• Trimble TerraSync
• Data collection
• User defined data dictionary
• Can be programmed to attribute in S-57
• Allows for in-Field S-57 attribution
• Challenges
• Does not display .000
• Only one background file can be viewed at time

Acquisition Processing Transition

• TerraSync produces a .ssf file
• GPS Pathfinder processes the .ssf file to
  create shape files separated by S-57 object type
• Pydro generic data parser used to import shape
  files

10
Processing Pydro

• Tide Correction via
  CARIS HIPS
• - Pydro creates PVDL in HDCS_Data
• S-57 attribution capability, (object type can
  be changed)
• Feature Management
• Automatic report functions
• Export of XML to CARIS
  Notebook
• Pydro is a NOAA in house software program

11
Processing CARIS HIPS Tide Correction
12
Processing CARIS Notebook

• Import of tide corrected managed features
  from Pydro XML files
• Import of source data via OIU
• Creation of line/area features
• Modification of source data, attribution and
  geographic extents
• Review of multibeam BASE surfaces shoreline
  features simultaneously
• Deliverables produced - .hob format containing
  S-57 attributed features for H-cell production

13
CARIS Notebook Object Import Utility

• Import
• Text Files
• Shape Files
• Database

• Mapping of fields
• retain/assign S-57 attribution

Processing Notebook - Editing

• Necessary Editing functions are
• changing of S-57 object type
• multiple node deletion
• splitting lines, node deletion/cutting
  from middle of line

16
GOALS - Revisited

• Deliver field product to Coast Survey which
  streamlines ENC update
• ACCOMPLISHED
• Display both acquired and reference data in an
  editable form in Notebook, with full S-57
  attribution
• ACCOMPLISHED
• Reduce ping-to-chart time
• PARTIALLY ACCOMPLISHED
• Minimize data conversions
• NOT ACCOMPLISHED

17
Future Streamlining
Pre-Acquisition eliminate use of Mapinfo,
duplicate work Acquisition .000 files viewed
directly in acquisition software,
both shoreline (TerraSync) and multibeam
(Isis) Batch processing of acquired
files or multiple files into one spreadsheet
for importation Processing Tide correction
alternatives Editing capabilities

The on going success of this project is
attributed to the hard work of the survey
personnel aboard the NOAA Ship FAIRWEATHER,
Physical Scientists Kaitlyn VanSant Megan
Palmer from the Pacific Hydrographic Branch, the
Pydro team at NOAAs HSTP division-especially
Jack Riley, and the CARIS Notebook team.
