    2. Abstract (Hidden Slide) Using FME SpatialDirect to Deliver NOAA Electronic Charts for Use in GIS Applications The National Oceanic and Atmospheric Administration’s (NOAA) Electronic Navigational Charts (ENC®) were developed to support marine transportation infrastructure and coastal management in the U.S. These ENC’s are available in the S-57 format, a data standard developed by the International Hydrographic Organization (IHO) for exchanging digital hydrographic data. To enable broad public access to their ENC’s by GIS applications, most of which cannot read S-57 data, NOAA built the “NOAA ENC Direct to GIS” web portal. This presentation discusses the role of FME SpatialDirect in enabling the public to access, display, query, and download all NOAA ENC data in a variety of GIS/CAD formats for non-navigational purposes. Specifically, I will discuss how FME is used to translate and transform ENC’s from S-57 to ESRI ArcSDE. I will also demonstrate the application to illustrate how FME SpatialDirect enables end users to specify the output format, coordinate system and the spatial extent of the data they wish to download. This session will benefit attendees who would like to see a real-world application of FME's data transformation and distribution capabilities. 2

    4. Today’s Agenda Background - Nautical Charts, ENCs, S-57 Product - ENC Direct to GIS FME data translation Spatial Direct Integration Benefits Looking forward Conclusion

    5. What is a Nautical Chart? A graphic depiction of the marine environment Nautical Charts are created with a specific purpose of being used as a tool for providing safe marine navigation.

    6. Navigation Product: Electronic Navigational Charts Electronic Navigational Charts (ENC) Databases of chart features used by navigation systems to produce a chart-like display ENCs the digital equivalent of paper or raster nautical chartsENCs the digital equivalent of paper or raster nautical charts

    7. What is S-57? International Hydrographic Organization (IHO) for Transfer Standard for Digital Hydrographic Data Uses International Standard Organization (ISO) 8211 file format Platform independent structure Provides a standard catalog for chart features ENC is a product specification for S-57

    8. S-57 Object Catalog Chart features belong to object classes Over 180 object classes defined Each object has set of descriptive attributes Object classes encoded as acronyms Attributes encoded as acronyms and enumeration Includes attribute data types and value domains

    9. Using ENCs in GIS Rich structure of the object catalog requires the use of data decoders to make sense of information contained in S-57 Off the shelf GIS software packages do not support ENC in native S-57 format S-57 standard is complex and hard to fully integrate in GIS

    10. ENC Direct: The GIS Solution

    11. ENC Direct Provides NOAA ENC data as online GIS data Uses ESRI ArcIMS internet mapping service Provides data for download in multiple GIS formats through FME SpatialDirect online data transformation Enables downloads to be customized to fit user requirements All ENCs currently available Updated monthly to include new coverage and ENC updates

    12. ENC Direct data flow FME Workbench workspace is used to convert S-57 to Shapefiles Attributes are decoded and irrelevant attributes are removed from output Chart features are merged together to create seamless GIS layers from NOAA ENCs Output shapefiles are loaded into ArcSDE ArcIMS is used to create a web based mapping interface Spatial Direct is used for Data Delivery

    13. NOAA ENC Direct to GIS A vast amount of information Over 1.5 million soundings 7,000 shipwrecks Over 10,000 marine geographic place names Bays, Channels, Rivers, Harbors, Shoals, Reefs, Coves, Inlets Over 1,000 restricted areas National Marine Sanctuaries, National Wildlife Refuges, Nature Preserves, National Parks, Military areas, Whale Critical Habitats

    14. GIS Layers Nautical Features Covering US Waters Contiguous information about Nautical Chart features available in GIS layers Example ENC Direct coastline layer contains data from 581 ENCs of the same scale that have been merged together

    21. Data Download Layers must be visible in ArcIMS. If layers are not visible then the user must zoom to the extent that they are visible. They then must manually adjust the spatial extent to what they desireLayers must be visible in ArcIMS. If layers are not visible then the user must zoom to the extent that they are visible. They then must manually adjust the spatial extent to what they desire

    22. Data Download

    23. ENC Direct without Scale Dependent layers A version of ENC Direct without scale dependency has been developed. This allows users to view and download only one layer at a time. They do not have to adjust the spatial extent for download.A version of ENC Direct without scale dependency has been developed. This allows users to view and download only one layer at a time.

    24. FME SpatialDirect Out of the box configuration Integration code available for download from fmepedia Easy integration with ESRI HTML Viewer WFS Service WFS Service can be read as a source for FME Workbench

    25. Benefits Streamlines and expands access to NOAA ENC data for non-navigational use Visualization of NOAA ENCs online Access to multiple cohesive chart features Soundings, Shipwrecks, Harbors, Marine Sanctuaries, Coastline, Vegetation, Landmarks, etc. Allows users to get the data that they want, how they want it

    26. Using Java Server Faces to access Spatial Direct Sometimes users do not need or want a map interface. Spatial Direct can interface with non GIS applications. This slide shows an Spatial Direct Integration with an Enterprise Java application.Sometimes users do not need or want a map interface. Spatial Direct can interface with non GIS applications.
